M76.50

Clinical Causes: Repeated stress or overuse during activities like jumping, running, or cycling Sudden increases in physical activity level Poor athletic technique or biomechanics Inadequate warm-up before exercise Muscle imbalances around the knee Inappropriate or worn-out sports equipment Previous knee injuries or weaknesses

Key Symptoms: Pain localized at the front of the knee, just below the kneecap Tenderness upon touching the affected area Swelling around the patellar tendon Stiffness in the knee, especially after periods of rest Pain that worsens with activity, such as jumping or running Possible weakness or a feeling of instability in the knee Discomfort during kneeling or direct pressure on the knee

Diagnosis Path: Diagnosis typically involves a healthcare professional conducting a physical examination to assess tenderness, swelling, and range of motion. They may perform specific tests, such as pressing on the tendon or having the patient perform bending motions, to identify tender areas. Imaging studies like X-rays can rule out other conditions but usually are not necessary for tendinitis. In some cases, MRI scans are used to evaluate the extent of inflammation or injury in the tendon tissue.

Treatment Protocols: Management of patellar tendinitis focuses on reducing inflammation and allowing the tendon to heal. Common approaches include: - Rest and activity modification to prevent aggravation - Applying ice packs to decrease swelling and pain - Nonsteroidal anti-inflammatory drugs (NSAIDs) as recommended by a healthcare provider - Physical therapy exercises to strengthen surrounding muscles and improve flexibility - Stretching routines targeting the quadriceps, hamstrings, and calf muscles - Using knee brace or strap to offload stress from the tendon - Gradual return to sports or activity once symptoms improve In chronic cases or severe injuries, more advanced interventions like corticosteroid injections or, rarely, surgical procedures may be considered under medical supervision.
