[Rehabilitation after total knee arthroplasty of hip and knee]

Numbers of total hip and knee arthroplasties are increasing on a regular basis. Clinical pathways tend to shorten the duration of hospitalization in acute care after surgery. Therefore, the preoperative preparation of the patient and his abilities for postoperative rehabilitation should be carefully addressed. Before the surgical intervention, it is recommended that the patient receives an educational program and a physical preparation. After the surgical intervention, the patient can benefit from a home-based rehabilitation program supervised by a physiotherapist, if there were no preoperative reasons for prolonging the hospital stay and if the surgery took place without complications. Some patients may benefit from postsurgical rehabilitation in a specialized locomotor rehabilitation long-stay care unit. The indications for inpatient multidisciplinary rehabilitation are : two simultaneous arthroplasties, revision of a previous hip or knee arthroplasty, postsurgical complications, advanced age, comorbidities influencing the rehabilitation process, social difficulties, necessity for adaptation of the environment, insufficient or unadapted out-patient (para)medical care. The goals of the rehabilitation treatment depend on the patient's characteristics and environment, on the properties of the prosthesis and on the postsurgical complications. The functional prognosis of a total joint arthroplasty of the knee or hip is excellent, provided that there are no post-surgical complications and that the patient benefits from adequate rehabilitation therapy. The present paper describes the different phases of rehabilitation treatment and the general and specific complications of total hip and knee arthroplasties that may influence the rehabilitation outcome.
