Common Conditions of the Knee

As one of the primary load-bearing joints in the body, the knee undergoes constant wear-and-tear stress and is one of the most commonly injured joints in the body. Common causes of knee pain and discomfort include ligament injuries (most commonly the Anterior Cruciate Ligament (ACL) and Medial Collateral Ligament (MCL)), meniscal tears (injury of the shock absorbing knee cartilage), arthritis, disorders of the kneecap (chondromalacia, bursitis, subluxation/dislocation, and tendonitis) and other injuries due to trauma such as bone fractures. Descriptions of some of the most common conditions of the knee that Dr. John Hoffman and Dr. Tuvi Mendel regularly diagnose and treat are listed below.

Physical Therapists

Orthopaedic Specialist’s occupational therapists are specifically trained to rehabilitate patients with knee disorders. You will receive a fully tailored therapy plan to help maximize the results of your recovery period following surgery.

Bracing: Splints and Orthotics

Our physical therapists commonly use custom splints or orthotics for treatment of lower extremity conditions. This type of treatment prevents unwanted movement to allow proper healing, reduce pain, and support a weak joint. Limiting the range of motion relieves stress on the affected area. A splint is a temporary aid commonly used following an injury or surgery and an orthosis is typically designed for long-term use. Depending on the problem, you may require either a soft or rigid orthotic support.
