M17.30
Unilateral post-traumatic osteoarthritis, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral post-traumatic osteoarthritis of the knee is a condition characterized by the degeneration of joint cartilage resulting from a previous injury to one knee. This form of osteoarthritis typically develops after trauma, such as a fracture, ligament tear, or other injuries, leading to joint deterioration over time. The condition primarily affects one knee, causing pain and functional limitations that can impact daily activities.
Causes & Symptoms
Clinical Causes: Previous knee injury or trauma, such as fractures, ligament tears (e.g., ACL or MCL injuries) Repetitive stress or overuse of the knee joint Inadequate healing of initial injuries leading to cartilage wear Joint instability following injury Previous knee surgeries that altered joint mechanics
Key Symptoms: Persistent knee pain, especially after activity or prolonged use Swelling and stiffness in the affected knee Reduced range of motion and flexibility A feeling of instability or giving way Crepitus or grinding sensation during knee movement Tenderness around the joint Possible visible deformity or asymmetry over time
Diagnostic & Treatment
Diagnosis Path: The diagnosis of post-traumatic osteoarthritis involves a combination of clinical evaluation and imaging studies. A healthcare provider will review medical history, focusing on prior knee injuries, and conduct a physical examination to assess swelling, point tenderness, and joint function. Imaging tests such as X-rays are essential to visualize cartilage loss, joint space narrowing, bone spurs, and any residual damage from previous trauma. Magnetic resonance imaging (MRI) may also be used for detailed assessment of soft tissues and cartilage health.
Treatment Protocols: Lifestyle modifications: weight management to reduce load on the knee Physical therapy: strengthening surrounding muscles to support knee stability Medications: nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation Corticosteroid injections: to decrease inflammation in the joint Assistive devices: braces, orthotics, or canes to improve mobility and offload stress Activity adjustments: avoiding high-impact activities Surgical interventions: procedures like arthroscopy, osteotomy, or knee replacement in advanced cases
