M94.269
Chondromalacia, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Chondromalacia of the knee, often referred to as patellofemoral pain syndrome, involves damage to the cartilage on the underside of the kneecap (patella). This cartilage acts as a cushion, allowing smooth movement of the knee joint. When it softens or deteriorates, it can cause discomfort, weakness, and problems with knee function. Although it can occur in anyone, it is especially common among young athletes and active individuals. The condition's exact cause can vary, and the severity of cartilage damage can range from mild to more extensive deterioration.
Causes & Symptoms
Clinical Causes: Repetitive stress or overuse, especially from activities like running, jumping, or squatting. Misalignment of the kneecap, leading to uneven pressure on the cartilage. Injury or trauma, such as a fall or blow to the knee. Muscle imbalances, especially weak quadriceps or tight hamstrings. Structural abnormalities of the knee joint or lower limb. Arthritis or other degenerative joint conditions.
Key Symptoms: A dull, aching pain around or behind the kneecap, especially during activity. Pain that worsens when climbing stairs, kneeling, or sitting for prolonged periods. A popping or grinding sensation when moving the knee. Swelling around the kneecap. Weakness or instability in the knee joint. Tenderness when touching the underside of the kneecap.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough clinical examination by a healthcare provider, who may assess knee stability, alignment, and range of motion. Imaging tests can be helpful to confirm cartilage damage or rule out other conditions. Common diagnostic tools include:
Treatment Protocols: Treatment of chondromalacia aims to reduce pain, improve knee function, and prevent further cartilage damage. Approaches can include both conservative measures and, in some cases, surgical options. Typical treatments are:
