Juvenile osteochondrosis of patella, left knee

Clinical Classification Guidelines

Medical Intelligence & Overview

Juvenile osteochondrosis of the patella is a condition that affects children and adolescents, involving abnormal development and degeneration of the cartilage and underlying bone in the kneecap (patella). Specifically impacting the left knee in this case, the condition can cause pain, swelling, and mobility issues. It is part of a group of disorders known as osteochondroses, which typically result from disrupted blood supply to the growing bones and cartilage during puberty.

Causes & Symptoms

Clinical Causes: Impaired blood circulation to the patellar growth plate during development Repetitive stress or overuse of the knee joint, especially in active children Trauma or injury to the knee, such as falls or direct blows Genetic predisposition affecting bone and cartilage development Rapid growth spurts that can strain the developing knee structures Biomechanical factors, like malalignment or abnormal gait patterns

Key Symptoms: Localized pain in the front of the knee, especially during activity or kneeling Swelling around the kneecap Tenderness upon palpation of the patella Limited range of motion in the knee joint A sense of instability or weakness in the knee Pain that worsens with physical activity and improves with rest Possible crepitus or grinding sensation during knee movement

Diagnostic & Treatment

Diagnosis Path: Physical examination to assess swelling, tenderness, and mobility X-ray imaging to visualize changes in the cartilage, bone development, and joint space Magnetic Resonance Imaging (MRI) for detailed images of cartilage and soft tissues Assessment of the patient’s medical history, activity level, and symptoms

Treatment Protocols: Rest and activity modification to minimize stress on the knee Application of ice packs to reduce swelling and pain Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief Physical therapy to strengthen surrounding muscles and improve joint stability Use of knee braces or supports to offload the affected area Gradual return to activities as symptoms improve In severe or persistent cases, surgical intervention may be considered to remove damaged tissue or realign the patella

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
