M76.5

Clinical Causes: Repetitive jumping, running, or cycling activities Sudden increase in intensity or duration of physical activity Poor conditioning or muscle imbalances around the knee Inadequate warm-up or stretching before exercise Fatigue of the quadriceps muscle group Poor biomechanics or improper technique during sports Inappropriate training surfaces or equipment

Key Symptoms: Pain just below the kneecap, especially during movement Tenderness or swelling around the patellar tendon Pain that worsens with activity and improves with rest Stiffness or tightness in the front of the knee A feeling of weakness or instability in the knee Potential grinding or crepitus when moving the knee

Diagnosis Path: Diagnosing patellar tendinitis involves a combination of medical history assessment, physical examination, and sometimes imaging tests. The healthcare provider will examine the knee for tenderness, swelling, and range of motion. They may also perform specific tests to elicit pain in the patellar tendon. Imaging studies such as ultrasound or MRI can be used to evaluate the extent of inflammation or any associated tissue damage if the diagnosis is uncertain or if the condition persists despite treatment.

Treatment Protocols: Rest and activity modification to avoid aggravating movements Ice application on the affected area to decrease swelling Non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief Physical therapy aimed at strengthening surrounding muscles and improving flexibility Stretching and strengthening exercises specifically tailored to the knee Use of supportive bracing or taping techniques to reduce stress on the tendon Gradual return to activity based on symptom improvement In severe or persistent cases, additional interventions like corticosteroid injections or, rarely, surgical procedures might be considered
