Patellar Tendon Repair

What Is a Patellar Tendon Tear?

The patellar tendon connects your kneecap (patella) to your shinbone (tibia). It plays a crucial role in straightening the knee and enabling movement like walking, jumping, or climbing stairs.
A tear or rupture of this tendon can occur from trauma, sports injuries, or overuse—often resulting in pain, swelling, and the inability to straighten the leg.

When Is Surgery Needed?

While small or partial tears may be treated with bracing and physical therapy, surgical repair is usually required for complete tendon ruptures.
Surgery restores function by reattaching the torn tendon to the kneecap using strong sutures, anchors, or surgical hardware.

Common Signs You May Need Patellar Tendon Repair

• Sudden pain at the front of the knee after a fall or jumping

• Swelling and bruising around the kneecap

• Difficulty walking or inability to extend the leg

• A noticeable indentation just below the kneecap

• A high-riding patella (patella alta)

What to Expect from Surgery

Patellar tendon repair is typically an outpatient procedure done under regional or general anesthesia. Here’s a general overview:

1. Surgical Procedure

• An incision is made at the front of the knee.

• Torn ends of the tendon are sutured and reattached to the patella.

• Sometimes augmentation with grafts is needed for chronic tears.

2. Recovery Timeline

• Weeks 1–6: Knee is immobilized in a brace; limited weight-bearing.

• Weeks 6–12: Gradual increase in motion and strength through physical therapy.

• 3–6 months: Return to light activity.

• 6–12 months: Full recovery and return to sports or high-demand activities.

Benefits of Timely Treatment

• Prevents long-term weakness or limited knee function

• Reduces pain and instability

• Restores mobility and strength

• Enables return to work, sports, or daily life

Risks and Considerations

As with any surgery, risks include:

• Infection

• Re-tear or failed healing

• Knee stiffness or weakness

• Blood clots

Choosing a skilled orthopedic surgeon and adhering to rehab instructions can greatly reduce complications.
