Definition

Patellar tendinitis is characterized by inflammation or degeneration of the patellar tendon, typically resulting from overuse or repetitive strain. This condition can lead to pain, swelling, and impaired function of the knee joint, particularly during activities that involve jumping, running, or squatting.

Symptoms

Patients with patellar tendinitis may experience the following symptoms:
- Pain: Localized pain just below the kneecap, which may worsen with activity and improve with rest.
- Swelling: Mild swelling around the patellar tendon.
- Stiffness: Stiffness in the knee, especially after prolonged periods of inactivity.
- Tenderness: Tenderness when pressing on the tendon area.
- Weakness: A feeling of weakness in the knee, particularly when attempting to jump or climb stairs.

Causes

The primary causes of patellar tendinitis include:
- Overuse: Repetitive activities that place stress on the knee, such as jumping, running, or heavy lifting.
- Biomechanical Issues: Poor alignment or mechanics during physical activities can increase stress on the patellar tendon.
- Inadequate Conditioning: Lack of proper strength and flexibility training can predispose individuals to tendon injuries.

Diagnosis

Clinical Evaluation

Diagnosis of patellar tendinitis typically involves:
- Patient History: A thorough history of symptoms, activity levels, and any previous knee injuries.
- Physical Examination: Assessment of pain location, swelling, and range of motion in the knee.
- Imaging Studies: While not always necessary, imaging such as ultrasound or MRI may be used to assess tendon integrity and rule out other conditions.

ICD-10 Classification

The ICD-10 code M76.5 specifically refers to "Patellar tendinitis." This classification is essential for accurate medical billing, epidemiological studies, and clinical research.

Treatment Options

Conservative Management

Initial treatment often includes:
