OSTEOARTHRITIS
Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis. However, evidence of combined kinematic chain exercise (CCE) in early-phase rehabilitation after TKA remains lacking. This study investigated the effects of CCE training on physical function, balance ability, and gait in 40 patients who underwent TKA. Participants were randomly assigned to the CCE (Total knee arthroplasty (TKA) is performed to reduce pain and improve physical function and quality of life when daily life is threatened by severe osteoarthritis [Both primary and revised TKA procedures are expected to increase globally with the increasing population of older adults [Currently, rehabilitation exercises for patients who have undergone TKA include balance, proprioceptive sensory increase, preoperative open-kinetic chain (OKCE), and close-kinetic chain exercises (CKCE), which help improve strength, physical function, balance, and walking ability [In early-phase rehabilitation after TKA, postoperative exercise generally involves OKCE, including continuous passive motion (CPM), which improves strength and ROM and can provide a minimal load to the operated joint [Despite the advantages of CCE in knee rehabilitation, limited studies have evaluated the performance of applying CCE to early-phase patients after TKA, and studies verifying the effects of CCE on physical function, balance ability, and gait are insufficient [
