In recent years, rehabilitation after total knee arthroplasty ( TKA ) has received widespread attention. There are few rehabilitation therapists who can provide rehabilitation guide for the patients receiving TKA in most hospitals of our country. There are some factors that may influence the effects of rehabilitation after TKA, including operation timing, timing of rehabilitation intervention and postoperative rehabilitation exercise. In early postoperative period, neuromuscular electrical stimulation ( NMES ) on the quadriceps femoris can help to improve the strength of quadriceps femoris and the function of apparatus of extention knee, increase the speed of walking and promote the recovery of knee joint function. A study showed that supra-physiological doses of testosterone before TKA could improve the postoperative muscle strength, increase the functional independence measure ( FIM ) score and shorten the hospitalization time. Based on the Lesquesne questionnaire data, the health status of the patients and quality of rehabilitation after TKA can be assessed.
