M76.52

Clinical Causes: Repeated stress or overuse of the knee joint during activities like jumping, running, or kneeling Sudden increases in physical activity intensity or duration Inadequate warm-up or stretching before sports or exercise Poor conditioning or muscle imbalance around the knee Inappropriate footwear that does not provide proper support Structural anomalies in the knee that increase stress on the patellar tendon Resuming activity too soon after injury or without proper rest

Key Symptoms: Localized pain at the bottom of the kneecap, especially during physical activity Tenderness when pressing on the front of the knee Swelling around the patellar tendon Weakness or stiffness in the knee, especially after rest A burning sensation or throbbing pain during or after activity Difficulty in jumping, running, or climbing stairs Pain that worsens with continued activity and lessens with rest

Diagnosis Path: Diagnosis typically involves a comprehensive physical examination by a healthcare provider, who will assess symptoms and examine the knee for tenderness, swelling, and range of motion. Imaging tests such as X-rays can rule out other conditions like fractures or arthritis, while MRI may be used to evaluate the extent of tendon injury or inflammation. A detailed history of activity levels and symptoms helps in confirming the diagnosis of patellar tendinitis.

Treatment Protocols: Management of patellar tendinitis focuses on reducing inflammation, alleviating pain, and allowing the tendon to heal. Common approaches include: - Rest and activity modification to prevent aggravation - Applying ice packs to reduce swelling - Over-the-counter pain relievers such as NSAIDs, as advised by a healthcare provider - Physical therapy exercises to strengthen and stretch the muscles around the knee - Use of patellar straps or braces to support the tendon - Gradual return to activity, guided by pain levels and healing progress - In severe cases, medical interventions like corticosteroid injections or, rarely, surgery may be considered if conservative treatments do not improve symptoms. Preventive measures involve proper training techniques, adequate warm-up routines, and ensuring appropriate footwear and equipment. Listening to your body and allowing sufficient rest between intense activities can also decrease the risk of developing tendinitis.
