This prospect i ve study compared 30 patients r and omly assigned to either a home exercise program or supervised outpatient physical therapy following arthroscopic partial medial meniscectomy . Their knee functions were assessed at 2 , 4 , and 8 weeks postoperatively using isokinetic analysis and subjective question naires . At each evaluation , the home exercise group performed as well or better than the supervised physical therapy group . There were no statistically significant differences between the two groups . At 4 weeks postoperation , the mean percent deficit in torque ( strength ) between the affected and unaffected limbs was 22.1 % in the supervised rehabilitation group and 22.0 % in the home exercise . The percent deficit in terms of endurance was 7.7 % in the supervised group and 3.6 % in the home group . Similar results were noted with regard to the patients ' subjective evaluations of their knee function and ability to resume work and recreational activities . We conclude that a well-planned , unsupervised home exercise knee rehabilitation program can produce equally good postoperative recovery as compared to a supervised outpatient physical therapy regimen in properly selected patients following arthroscopic partial meniscectomy of the knee Background : There have been no long-term follow-up studies comparing a predominantly home-based rehabilitation program with a st and ard physical therapy program  after anterior cruciate ligament ( ACL ) reconstruction . Demonstrating the long-term success of such a cost-effective program would be beneficial to guide future rehabilitation practice . Purpose : To determine whether there were any differences in long-term outcome between recreational athletes who performed a physical therapy-supervised rehabilitation program  and those who performed a primarily home-based rehabilitation program  in the first 3 months after ACL reconstruction . Study Design : R and omized clinical trial ; Level of evidence , 1 . Methods : Patients were r and omized before ACL reconstruction surgery to either the physical therapy-supervised ( 17 physical therapy sessions ) or home-based ( 4 physical therapy sessions ) program . Eighty-eight of the original 129 patients returned 2 to 4 years after surgery to assess their long-term clinical outcomes . Primary outcome was the ACL quality of life question naire ( ACL QOL ) . Secondary outcomes were bilateral difference in knee extension and flexion range of motion , sagittal plane knee laxity , relative quadriceps and hamstring strength , and objective International Knee Documentation Committee score . Unpaired t tests and a chi-square test were used for the comparisons . Results : The home-based group had a significantly higher mean ACL QOL score ( 80.0 ± 16.2 ) than the physical therapy-supervised group ( 69.9 ± 22.0 ) a mean of 38 months after surgery ( P = .02 , 95 % confidence interval [ CI ] : 1.7 , 18.4 ) . The mean change in ACL QOL score from before surgery to follow-up was not significantly different between the groups ( physical therapy = 40.0 , home = 45.8 , P = .26 , 95 % CI : −15.8 , 4.4 ) . There were no significant differences in the secondary outcome measures . Conclusion : This long-term study upholds the short-term findings of the original r and omized clinical trial by demonstrating that patients who participate in a predominantly home-based rehabilitation program in the first 3 months after ACL reconstruction have similar 2- to 4-year outcomes compared with those patients who participate in a more clinical ly supervised program BACKGROUND AND PURPOSE Manual therapy and exercise have not previously been compared with a home exercise program for patients with osteoarthritis ( OA ) of the knee . The purpose of this study was to compare outcomes between a home-based physical therapy program and a clinical ly based physical therapy program . SUBJECTS One hundred thirty-four subjects with OA of the knee were r and omly assigned to a  clinic treatment group ( n=66 ; 61 % female , 39 % male ; mean age [+/-SD]=64+/-10 years ) or a home exercise group ( n=68 , 71 % female , 29 % male ; mean age [+/-SD]=62+/-9 years ) . METHODS Subjects in the clinic treatment group received supervised exercise , individualized manual therapy , and a home exercise program over a 4-week period . Subjects in the home exercise group received the same home exercise program initially , reinforced at a clinic visit 2 weeks later . Measured outcomes were the distance walked in 6 minutes and the Western Ontario and McMaster Universities Osteoarthritis Index ( WOMAC ) . RESULTS Both groups showed clinical ly and statistically significant improvements in 6-minute walk distances and WOMAC scores at 4 weeks ; improvements were still evident in both groups at 8 weeks . By 4 weeks , WOMAC scores had improved by 52 % in the clinic treatment group and by 26 % in the home exercise group . Average 6-minute walk distances had improved about 10 % in both groups . At 1 year , both groups were substantially and about equally improved over baseline measurements . Subjects in the clinic treatment group were less likely to be taking medications for their arthritis and were more satisfied with the overall outcome of their rehabilitative treatment compared with subjects in the home exercise group . DISCUSSION AND CONCLUSION Although both groups improved by 1 month , subjects in the clinic treatment group achieved about twice as much improvement in WOMAC scores than subjects who performed similar unsupervised exercises at home . Equivalent maintenance of improvements at 1 year was presumably due to both groups continuing the identical home exercise program . The results indicate that a home exercise program for patients with OA of the knee provides important benefit . Adding a small number of additional clinical visits for the application of manual therapy and supervised exercise adds greater symptomatic relief Arthritis has been identified as the most common cause of disability in the United States ( 1 , 2 ) . Thirty-three percent of persons 63 to 94 years of age are affected by osteoarthritis of the knee , which often limits the ability to rise from a chair , st and comfortably , walk , and use stairs ( 3 , 4 ) . Acetaminophen and nonsteroidal anti-inflammatory drugs ( NSAIDs ) are commonly used to treat osteoarthritis . Use of NSAIDs can lead to gastric complications , increased risk for hospitalization , and death ( 5 ) . Other treatment options for persons with osteoarthritis of the knee include physical therapy exercise and treatment programs , cortisone injections , and joint replacement surgery . Puett and Griffin ( 6 ) review ed 15 controlled trials of nonmedicinal , noninvasive therapies for hip and knee osteoarthritis from 1966 through 1993 ( 6 ) . The authors concluded that exercise reduces pain and improves function in patients with osteoarthritis of the knee , but the optimal exercise regimen has not been determined . Fitness walking , aerobic exercise , and strength training have all been reported to result in functional improvement in patients with osteoarthritis of the knee ( 6 - 12 ) . Unweighted treadmill walking has not been shown to decrease pain associated with osteoarthritis of the knee ( 13 ) . Other research ers ( 14 , 15 ) have concluded that exercise may benefit patients with osteoarthritis but advise that long-term studies are required to determine the appropriate amounts of exercise to avoid accelerating the underlying process of arthritis . Active and passive range-of-motion exercise is considered an important part of rehabilitation programs for patients with osteoarthritis ( 16 - 18 ) . Physical therapists frequently use manual therapy procedures as part of comprehensive rehabilitation programs to help patients regain joint mobility and function ( 19 ) . We evaluated the effectiveness of manual physical therapy for osteoarthritis of the knee , as applied by physical therapists with formal training in such an approach ( 20 ) . Our hypothesis was that physical therapy consisting of manual therapy to the knee , hip , ankle , and lumbar spine combined with range-of-motion , strengthening , and cardiovascular exercises would be more effective than placebo for improving function , decreasing pain and stiffness , and increasing the distance walked in 6 minutes . Methods Patients Eighty-three patients with osteoarthritis of the knee were r and omly assigned to receive treatment ( n=42 ; 15 men and 27 women [ mean age , 60 11 years ] ) or placebo ( n=41 ; 19 men and 22 women [ mean age , 62 10 years ] ) . All patients were referred by physicians to physical therapy for osteoarthritis of the knee . Physicians at the various clinics in the medical center who normally see patients with osteoarthritis of the knee were informed of the study so that appropriate referrals could be made . If the patients met our inclusion criteria , they were offered the opportunity to participate . The main inclusion criterion was a diagnosis of osteoarthritis of the knee based on fulfillment of one of the following clinical criteria developed by Altman and colleagues [ 21 ] : 1 ) knee pain , age 38 years or younger , and bony enlargement ; 2 ) knee pain , age 39 years or older , morning stiffness for more than 30 minutes , and bony enlargement ; 3 ) knee pain , crepitus on active motion , morning stiffness for more than 30 minutes , and bony enlargement ; or 4 ) knee pain , crepitus on active motion , morning stiffness for more than 30 minutes , and age 38 years or older . Altman and colleagues found this criteria to be 89 % sensitive and 88 % specific ( 21 - 23 ) . Patients were required to be eligible for military health care , have had no surgical procedure on either lower extremity in the past 6 months , and have no physical impairment unrelated to the knee that would prevent safe participation in a timed 6-minute walk test or any other aspect of the study . Patients had to have sufficient English- language skills to comprehend all explanations and to complete the assessment tools . They were also required to live within a 1-hour drive of the physical therapy clinic . Patients who could not attend the required number of visits or had received a cortisone injection to the knee joint within the previous 30 days were not enrolled . Patients were instructed to keep taking any current medications and not to start taking new medications for osteoarthritis during the clinical treatment and 8-week follow-up . Therapy with any osteoarthritis medication must have been initiated at least 30 days before participation in the study . The study was approved by the institutional review board of Brooke Army Medical Center , Fort Sam Houston , Texas . All patients completed an informed consent form and were advised of the risks of the study , including increased symptoms , injuries from falls , and cardiovascular events . No external funding was received for this study . Procedure Patients who met the inclusion criteria were r and omly assigned to one of two groups . Blank folders were numbered from 1 to 100 and were given concealed codes for the group of assignment , determined by a r and om-number generator . When a patient was eligible and gave consent to participate , the treating therapist drew the next folder from the file , which determined the group of assignment . The treatment group received a combination of manual physical therapy and supervised exercise . The placebo group received ultrasound at a subtherapeutic intensity . Neither group was aware of the treatment that the other group was receiving . Demographic data collected for each patient included age , sex , occupation , height , weight , duration of symptoms , presence of symptoms in one or both knees , previous knee surgery , medications , and present activity level . Knee radiographs were obtained and read by a radiologist who assigned a radiographic severity rating for osteoarthritis ( 24 ) . Dependent variables measured in this study were the Western Ontario and McMaster Universities Osteoarthritis Index ( WOMAC ) score ( 25 ) and distance covered during a timed 6-minute walk test . The WOMAC Osteoarthritis Index consists of 24 questions , each corresponding to a visual analogue scale . This test has been shown to be a reliable , valid , and responsive multidimensional outcome measure for evaluation of patients with osteoarthritis of the hip or knee ( 26 ) . The timed 6-minute walk test measures the distance a patient walks in 6 minutes and has been demonstrated to be a reliable measurement of functional exercise capacity ( 27 ) . All measurements of dependent variables were obtained by a trained research assistant who was blinded to group assignment . After research assistants obtained pretreatment values for the dependent variables , patients returned to the treating physical therapist for thorough st and ardized clinical examination of the knee , hip , ankle , and lumbar spine . Treatment was initiated according to group assignment . The treatment group received manual physical therapy as indicated by the results of the examination . The manual therapy treatment techniques , consisting of passive physiologic and accessory joint movements , muscle stretching , and soft-tissue mobilization , were applied primarily to the knee . The same treatments were also administered to the lumbar spine , hip , or ankle if these areas showed limitation in active or passive movement , were symptomatic , or were contributing to overall lower limb dysfunction ( 28 - 31 ) . A minimal pain level was not exceeded in any treatment . The treatment group also performed a closely supervised st and ardized knee exercise program at each of the eight treatment sessions . This program consisted of active range-of-motion exercises for the knee , muscle strengthening exercises for the hip and knee , muscle stretching for the lower limbs , and riding a stationary bike . All of the activities were mutually reinforcing , with repeated gentle challenges to the end ranges of movement . An outline of the exercise program is shown in the Appendix Figure . The physical therapist increased the number of strengthening exercise bouts and the stationary bike riding time on the basis of patient tolerance . The current literature provides efficient methods to produce the desired effects of increasing strength , flexibility , and range of motion ( 32 - 35 ) . At each session , the physical therapist examined the patient for adverse signs and symptoms , such as increased pain , joint effusion , and increased skin temperature over knee joints . These signs and symptoms of osteoarthritis had to be stable or decreasing before manual therapy or exercise was progressed . Patients exercised in a painless or minimally painful manner . If any post-treatment or exercise soreness lasted more than a few hours , the regimen was decreased accordingly for that patient . The placebo group received treatment by the physical therapist that consisted of subtherapeutic ultrasound for 10 minutes at an intensity of 0.1 W/cm2 and 10 % pulsed mode ( lowest setting and greatest cycle interruption ) to the area of knee symptoms . The placebo group received the same subjective and h and s-on objective reevaluation before and after each session as the treatment group . The amount of time directly spent with the treating therapist was approximately 30 minutes for both groups . The treatment group required an additional 30 to 45 minutes to perform their exercises in the clinic . Both groups were treated twice weekly for 4 weeks , for a total of eight clinic treatments . Patients in the treatment group also performed the same exercises at home , except for the closed-chain strengthening exercises , on the days on which they were not treated in the physical therapy clinic . They also walked at home each day at a comfortable pace and distance . The treating physical therapist instructed each patient in the performance of the exercises and provided a detailed h and out containing instructions and photographs of the exercises . Each patient maintained a home exercise BACKGROUND Development of this guideline was undertaken by the Exercise for People with Cancer Guideline Development Group , a group organized by Cancer Care Ontario 's Program in Evidence -Based Care ( pebc ) . The purpose of the guideline was to provide guidance for clinicians with respect to exercise for patients living with cancer , focusing on the benefits of specific types of exercise , recommendations about screening requirements for new referrals , and safety concerns . METHODS Consistent with the pebc 's st and ardized approach , a systematic search was conducted for existing guidelines , and systematic literature search es were performed in medline and embase for both systematic review s and primary literature . Content and methodology experts performed an internal review , which was followed by an external review by targeted experts and intended users . RESULTS The search identified three guidelines , eighteen systematic review s , and twenty-nine r and omized controlled trials with relevance to the topic . The present guideline provides recommendations for the duration , frequency , and intensity of exercise appropriate for people living with cancer . It also provides recommendations for pre-exercise assessment , safety concerns , and delivery models . CONCLUSIONS There is sufficient evidence to show that exercise provides benefits in quality of life and muscular and aerobic fitness for people with cancer both during and after treatment , and that it does not cause harm . The present guideline is intended to support the Canadian Society for Exercise Physiology 's Canadian physical activity guidelines . The recommendations are intended for clinicians and institutions treating cancer patients in Ontario , and for policymakers and program planners involved in the delivery of exercise programs for cancer patients BACKGROUND AND PURPOSE Controversy exists about the effectiveness of physical therapy after arthroscopic partial meniscectomy . This r and omized controlled trial evaluated the effectiveness of supervised physical therapy with a home program versus a home program alone . SUBJECTS Eighty-four patients ( 86 % males ; overall mean age=39 years , SD=9 , range=21 - 58 ; female mean age=39 years , SD=9 , range=24 - 58 ; male mean age=40 , SD=9 , range=21 - 58 ) who underwent an uncomplicated arthroscopic partial meniscectomy participated . METHODS Subjects were r and omly assigned to either a group who received 6 weeks of supervised physical therapy with a home program or a group who received only a home program . Blinded test sessions were conducted 5 and 50 days after surgery . Outcome measures were : ( 1 ) Hughston Clinic question naire , ( 2 ) Medical Outcomes Study 36-Item Short-Form Health Survey ( SF-36 ) and EuroQol EQ-5D ( EQ-5D ) question naires , ( 3 ) number of days to return to work after surgery divided by the Factor Occupational Rating System score , ( 4 ) kinematic analysis of knee function during level walking and stair use , and ( 5 ) horizontal and vertical hops . RESULTS No differences between groups were found for any of the outcomes measured . DISCUSSION AND CONCLUSION The results indicate that the supervised physical therapy used in this study is not beneficial for patients in the early period after uncomplicated arthroscopic partial meniscectomy Providing physical therapy service on Sundays is a much debated topic among hospital administrators . The purpose of this study was to determine if 7 days per week of physical therapy coverage results in shorter lengths of stay and differing discharge status than 6 days per week . A total of 140 subjects with hip or knee arthroplasty participated ; there were 80 in the 6-day groups and 60 in the 7-day groups . Data on postoperative length of stay , discharge destination , and discharge disposition were collected by retrospective medical record review . The Mann-Whitney U test was used to test for differences in length of stay data , and the chi-squared test was used to test for differences in discharge disposition and discharge destination . No significant differences in postoperative length of stay , discharge destination , nor discharge disposition existed between the 6- and 7-day physical therapy coverage hip or knee arthroplasty groups . However , the power of the statistical tests applied was low . This study provides no evidence that 7-day per week physical therapy results in shortened postoperative length of stay , differing discharge destination , nor differing discharge disposition for patients undergoing hip or knee arthroplasty Background Osteoarthritis ( OA ) is a common cause of pain and disability , and is the most common form of arthritis in the Western world . The most common joint to be affected is the knee . Pain and functional disability are common symptoms , which can lead to reduced quality of life and increase the risk of further morbidity . Current treatment aims to educate patients about the management of OA , reduce pain , improve function , decrease disability and reduce the progression of the disease . Education with clients has been described as a set of planned educational activities design ed to improve patients ' health behaviours and /or health status . The purpose of self‐education is to maintain or improve health , or , in some cases , to slow deterioration by increasing participant 's perception of self efficacy defined as an ability to control or manage various aspects of OA . To date , there is no systematic review of the literature undertaken to identify the effectiveness of self‐management educational activities for osteoarthritis of the knee . Objective The objective of this systematic review is to evaluate the effectiveness of  self‐management educational interventions on function and quality of life for adult subjects with OA of the knee . Search strategy A comprehensive search strategy was undertaken on data bases available from University of South Australia from their inception to January 2007 . Selection criteria R and omised controlled trials or clinical controlled trials were sought which evaluated any self management interventions for osteoarthritis knee . Critical appraisal of study quality was undertaken using Joanna Briggs Institute critical appraisal instruments . Data extraction was via the Joanna Briggs Institute st and ard data extraction form for evidence of effectiveness , and Review Manager Software was used to calculate comparative statistics . Results Thirteen trials were included in the review . Trials were clinical ly and method ologically heterogeneous . Pooled results indicate evidence of a beneficial effect from  self management strategies with reducing pain ( SMD ‐0.25 , 95%CI ‐0.36 to ‐0.13 , 11 trials 1379 participants ) . There was no effect on physical function ( SMD 0.13 , 95%CI ‐0.33 to ‐0.08 , eight trials , 1156 subjects ) . No beneficial effects were found from self management interventions with improving quality of life . We also found the exercise component of self management ( four trials ) demonstrated a benefit with reducing pain , improving function and quality of life . Exercise also offered a benefit over no exercise  . Overall method ological quality was moderate . Discussion Pooled results indicate evidence of a beneficial effect from self management strategies with reducing pain and improving function . Significant heterogeneity was found between trials . This was controlled for in the analysis but may be explained by heterogeneity in both the intervention and control group . The exercise component of self management programmes appears to contribute a significant benefit . Conclusion There is encouraging evidence of a small benefit from exercise in self management programs . Clear guidelines can not be provided for practice regarding the exercise content due to heterogeneity but overall benefit suggests this component should be emphasized and implemented in primary care self management programmes Background Osteoarthritis is the most common reason for pain in older adults , and the individual and economic burden of this disease is immense . The chronic character of osteoarthritis requires a long-term therapeutic treatment . In this regard life-style interventions such as physical exercises that can be carried out by the patient himself are recommended as first line treatment . There is evidence for the short-term benefit of exercise therapy in terms of pain reduction and physical functioning . Nonetheless research agendas highlight the need for multifaceted interventions that incorporate exercise strategies into patient care . Studies should be conducted with appropriate sample sizes and should allow statements on long-term effects as well as cost-utility and safety . These open questions are under the scope of this study . Methods / design This is a controlled study in the context of health services research . The study population consists of n = 1400 subjects with hip or knee osteoarthritis . The  intervention group will be recruited from participants of a country-wide health insurance offer for people with hip or knee osteoarthritis . Potential participants for the control group ( ratio 10:1 ( control vs. intervention ) will be filtered out from the insurance data base according to pre-defined matching criteria and asked by letter for their participation . The final statistical twins from the responders ( 1:1 ) will be determined via propensity score matching . The progressive training intervention comprises 8 supervised group sessions , supplemented by home exercises ( 2/week over 11 weeks ) . Exercises include mobilization , strengthening and training of postural control . Primary outcomes are pain and function measured with the WOMAC Index immediately after the intervention period . Among other things , health related quality of life , self-efficacy , cost utility and safety will be evaluated as secondary outcomes . Participants will be followed up 6 , 12 and 24 month after baseline . Discussion Results of this trial will document the effects of clinical as well as economic outcomes in a regular health care setting on the basis of a large sample size . As such , results of this trial might have great impact on future implementations of group- and home-based exercises in hip or knee osteoarthritis . Trail registration German Clinical Trial Register DRKS00009251 . Registered 10 September 2015 Background The reasoning behind evaluating medical interventions is that a hierarchy of methods exists which successively produce improved and therefore more rigorous evidence based medicine upon which to make clinical decisions . At the foundation of this hierarchy are case studies , retrospective and prospect i ve case series , followed by cohort studies with historical and concomitant non-r and omized controls . Open-label r and omized controlled studies ( RCTs ) , and finally blinded , placebo-controlled RCTs , which offer most internal validity are considered the most reliable evidence . Rigorous RCTs remove bias . Evidence from RCTs forms the basis of meta-analyses and systematic review s. This hierarchy , founded on a pharmacological model of therapy , is generalized to other interventions which may be complex and non-pharmacological ( healing , acupuncture and surgery ) . Discussion The hierarchical model is valid for limited questions of efficacy , for instance for regulatory purpose s and newly devised products and pharmacological preparations . It is inadequate for the evaluation of complex interventions such as physiotherapy , surgery and complementary and alternative medicine ( CAM ) . This has to do with the essential tension between internal validity ( rigor and the removal of bias ) and external validity ( generalizability ) . Summary Instead of an Evidence Hierarchy , we propose a Circular Model . This would imply a multiplicity of methods , using different design s , counterbalancing their individual strengths and weaknesses to arrive at pragmatic but equally rigorous evidence which would provide significant assistance in clinical and health systems innovation . Such evidence would better inform national health care technology assessment agencies and promote evidence based health reform
In select young and healthy population with few co morbidities  supervised physical therapy  is no more beneficial than a  home exercise program  following relatively simple knee surgical procedures ( arthroscopic meniscetomy ) .
Physical therapy is common following a knee surgery .
With rising healthcare costs there is debate as to the appropriateness of outpatient physical therapy following such interventions .
Many of the existing controlled trials have concluded that there is no benefit to subjects that receive supervised physical therapy when compared to subjects that perform their exercises at home .
The purpose of this systematic review was to consider the existing evidence regarding benefit following  knee surgery  and evaluate the quality , internal and external validity of such evidence .
