M22.41
Chondromalacia patellae, right knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Chondromalacia patellae, commonly known as runner's knee, involves softening and deterioration of the cartilage on the underside of the kneecap (patella). When it affects the right knee, it can lead to pain and discomfort, especially during movement. This condition often impacts athletes and active individuals but can also occur due to other factors such as injury or abnormal kneecap alignment.
Causes & Symptoms
Clinical Causes: Overuse or repetitive stress on the knee joint Trauma or injury to the kneecap Misalignment of the kneecap (patellar maltracking) Muscle imbalance around the knee Uneven leg length or structural deformities Abnormal wear and tear due to aging Poor biomechanics during activities
Key Symptoms: Dull, aching pain around or behind the kneecap Pain worsened by activities like climbing stairs, squatting, or running A sensation of grinding or popping when moving the knee Swelling or tenderness around the kneecap Feelings of weakness or instability in the knee Increased discomfort after prolonged sitting with knees bent
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination to assess knee movement and pain points. Healthcare providers may use imaging tests such as X-rays or MRI scans to evaluate cartilage health, patellar alignment, and rule out other issues like ligament injuries or arthritis. A detailed patient history and symptom review help inform the diagnosis.
Treatment Protocols: Treatment aims to reduce pain, improve knee function, and prevent further cartilage damage. Common approaches include: - Rest and activity modification to avoid aggravating movements - Ice application to reduce swelling and pain - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy focusing on strengthening the quadriceps and hip muscles to support the kneecap - Stretching exercises to improve flexibility - Use of knee braces or taping techniques to enhance alignment - In advanced cases, surgical options such as cartilage repair or realignment procedures may be considered. Adopting a knee-friendly activity plan and following healthcare advice can assist recovery and minimize the risk of future issues.
