Internal derangement of the knee may involve injury to muscle, ligament, tendon, meniscus, or bone. Rehabilitation will depend on the nature of the underlying pathology, the extent of injury, type of treatment (i.e., surgical, nonsurgical), and the functional goals of the individual.
The primary focus of rehabilitation for internal derangement of the knee is to control pain and swelling and regain function. Physical therapy may be initiated according to the recommendations of the physician to restore range of motion and strength to the involved knee. Initially, the therapist may use modalities such as electrical stimulation and cold (cryotherapy) to reduce swelling and control edema. Therapists may instruct individuals to use assistive devices (i.e., walker, crutches, cane) according to weight bearing status to promote independent ambulation. Isometrics, followed by open and closed chain strengthening exercises, are progressed as tolerated with emphasis on function. As knee flexibility and strength return, individuals may progress to balance and proprioception activities until full function is achieved.
As part of the rehabilitation program, individuals are instructed in a home exercise program that usually should be continued after discharge to maximize return of knee strength and stability. The treating physician should guide the resumption of heavy work and sports activities. |
