Standard library functions. The standard library functions are built-in functions in C programming to handle tasks such as mathematical computations, I/O processing, string handling etc. These functions are defined in the header file. When you include the header file, these functions are available for use.
Knee replacement. Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis,[1] and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis.
Knee Replacement Approaches. What exactly happens during a total knee replacement surgery? How does the surgeon remove the existing knee joint components and replace them with a prosthetic implant? The surgery begins with an incision into the tissue to allow access to the patella (kneecap) and quadriceps muscle (on top of the upper leg).
