ICD-10: M17.32

Unilateral post-traumatic osteoarthritis of the left knee, classified under ICD-10 code M17.32, is a specific diagnosis that pertains to the degenerative joint disease that develops following an injury to the knee. This condition is characterized by the deterioration of cartilage and changes in the bone structure, leading to pain, stiffness, and reduced mobility in the affected knee.

Clinical Description

Definition

Unilateral post-traumatic osteoarthritis refers to the development of osteoarthritis in one knee joint as a direct consequence of a previous traumatic injury. This can include fractures, ligament tears, or other significant injuries that disrupt the normal anatomy and function of the knee joint. The left knee is specifically indicated in this code, highlighting that the condition is not present in the right knee.

Pathophysiology

The pathophysiology of post-traumatic osteoarthritis involves several processes:
- Cartilage Damage: Following trauma, the cartilage may be damaged or eroded, leading to increased friction between the bones during movement.
- Bone Changes: The underlying bone may undergo changes, such as sclerosis (hardening) or the formation of osteophytes (bone spurs), which can contribute to joint pain and stiffness.
- Inflammation: The injury can trigger an inflammatory response, which may exacerbate the degeneration of cartilage and lead to further joint damage over time.

Symptoms

Patients with unilateral post-traumatic osteoarthritis of the left knee typically experience:
- Pain: Often worsens with activity and improves with rest.
- Stiffness: Particularly noticeable after periods of inactivity or in the morning.
- Swelling: May occur due to inflammation or fluid accumulation in the joint.
- Decreased Range of Motion: Difficulty in fully bending or straightening the knee.
- Crepitus: A grating sensation or sound during movement of the knee.

Diagnosis

Diagnosis of M17.32 involves a combination of:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and functional limitations.
- Imaging Studies: X-rays are commonly used to identify joint space narrowing, osteophyte formation, and other degenerative changes. MRI may be utilized for a more detailed view of soft tissue structures.
- Patient History: A history of knee trauma or injury is crucial in establishing the diagnosis.

Treatment Options

Conservative Management

Initial treatment often includes:
- Physical Therapy: To strengthen the muscles around the knee and improve flexibility.
