knee PATELLAR TENDONITIS
DEFINITION:
- Also known as “Jumper’s Knee”.
- An inflammatory process involving the tendon attaching the patella (knee cap) to the tibia. (See illustration).
- The patella tendon is part of the knee extensor mechanism.
MECHANISM OF INJURY / HOW IT OCCURS:
- A result of repetitive forceful pulling on the tendon, extensive kneeling, or squatting maneuvers.
- Commonly seen in individuals involved in activities requiring a lot of jumping such as basketball. Also seen in runners, volleyball and soccer.
SYMPTOMS:
- Individuals will complain of pain over the patellar tendon which is exacerbated with jumping, kneeling, squatting, as well as climbing or descending stairs.
- May complain of swelling.
DIAGNOSIS:
- Physical examination will reveal tenderness over the tendon.
- Hyperflexion of the knee may exacerbate symptoms.
- Radiographic studies to include plain x-rays and Magnetic resonance imaging (MRI) may be indicated to assist with the diagnosis.
TREATMENT/REHABILITATION:
- Ice to reduce swelling and inflammation.
- Rest – participate in cross training. Anti inflammatory medications (NSAIDs).
- Anti-inflammatory medications (NSAIDS).
- Therapy to work on stretching and strengthening once symptoms have subsided. (See exercises for patellar tendonitis).
- Occasionally a brace/strap may be of benefit.
