Patellar Tendonitis Rehab

Your patellar tendon attaches your quadriceps muscles at the front of your thigh to your shin bone, or tibia, in your lower leg. The tendon begins just below the kneecap, or patella, and inserts at the tibia tuberosity, a large bump at the top of your shin bone.

Tendons are made of tough fibrous tissue that is continuous with the muscle, attaching it securely to bone. As the muscle shortens, it pulls on the bone to which it is attached, producing movement. The job of the patellar tendon is to straighten the knee by pulling on the tibia.

Patellar Tendonitis is a common athletic overuse injury, although it can occur in non-athletic populations. During physical activity, the patellar tendon is subjected to great force loads as it straightens the knee during walking, running and jumping. Patellar tendon dysfunction is sometimes called jumper’s knee due to its prevalence in sports that involve jumping.

Tendinitis refers to inflammation of the tendon, but the term tendinosis offers a more accurate description of jumper’s knee, because tendon injuries tend to be degenerative rather than inflammatory.

Patellar Tendonitis Causes

Tendinosis occurs when excessive forces cause disruption of the tendon cells, called tenocytes, making them weaker and less able to cope with repetitive load. If not given time to heal, painful degeneration of the entire tendon may occur.

Causes of patellar tendinosis (tendonitis) include:

Sports like basketball that require repetitive jumping and landing
Running
Poor flexibility in the quadriceps and/or hamstrings
An elevated kneecap (patella alta)
Inadequate recovery time between activity sessions

Patellar Tendonitis Symptoms

Sharp pain along the tendon after running or jumping
Persistent pain or aching at the front of the knee
Tenderness to touch
Stiffness and pain in the tendon first thing in the morning

Patellar Tendonitis Diagnosis

Diagnosis is based on symptoms and a physical exam. At NYDNR, we confirm our diagnosis with high resolution diagnostic ultrasound, to rule out other possible causes of knee pain.

Patellar Tendonitis Treatment

Treatment for patellar Tendonitis (Tendinosis) is geared to managing symptoms while the knee recovers and heals. Discontinuing activities that cause pain, applying ice and taking NSAIDs may help. Stretching the muscles of the upper leg can reduce load on the patellar tendon.

At NYDNR, we take an active approach to treating patellar tendinosis (Tendonitis). Some of our treatment methods include:

Patellar Tendonitis Physical Therapy

Jumper’s knee physical therapy may include eccentric loading, knee stability exercises, and strengthening and stretching of the upper leg muscles.

ESWT (Extracorporeal Shock Wave Therapy)

Tendon tissue is not highly vascular, and getting nutrients to the cells is important for healing. ESWT is a non-invasive treatment that stimulates cellular regeneration and increases the flow of blood and nutrients to damaged cells to accelerate healing.

At NYDNR, part of our protocol for patellar tendonitis rehab is biomechanical evaluation and retraining. Making minor corrections in motor skills can improve performance and reduce the risk of injury.

Absence of pain alone is not enough to ensure the patellar tendon has fully healed. We monitor our patients’ progress with ongoing ultrasonography and biomechanical analysis. At NYDNR, we want our athletes to return to sport with confidence, fully recovered, and with a low risk of re-injury.
