Quadriceps Tendon Tear

A quadriceps tendon tear is a significant injury that involves a rupture of the tendon connecting the quadriceps muscles to the patella (kneecap). This injury typically requires prompt medical attention and can be debilitating, affecting mobility and knee function. Here’s an overview of quadriceps tendon tears, including causes, symptoms, diagnosis, treatment, and rehabilitation.

Common Symptoms

  • Sudden Pain: Acute, severe pain in the front of the knee or upper shin, often following a jumping or landing motion.
  • Swelling: Immediate swelling around the knee joint.
  • Difficulty Straightening the Knee: Inability to straighten the knee against resistance (active extension).
  • Gap or Divot: Sometimes a visible gap or depression above the kneecap where the torn tendon has retracted.

Cause & Anatomy

  • Sudden Force: Direct trauma to the knee, such as a fall or impact.
  • Degenerative Changes: Tendon degeneration over time, often seen in older adults or athletes with chronic overuse.
  • Steroid Injections: Long-term use of corticosteroid injections near the tendon can weaken it, increasing the risk of tears.


  • Quadriceps Tendon: A strong, thick tendon that connects the quadriceps muscles (front thigh muscles) to the patella.
  • Function: The quadriceps tendon allows the quadriceps muscles to extend the knee, essential for activities such as walking, running, and jumping.


  • Physical Examination: Assessment of symptoms, range of motion, and strength of the knee.
  • Imaging Tests: X-rays to evaluate for any associated fractures and MRI (Magnetic Resonance Imaging) to confirm the diagnosis and assess the extent of tendon tear.

Non-Surgical Treatment

  • Partial Tears: Partial tears may be managed non-surgically with immobilization in a knee brace, followed by physical therapy to regain strength and function.

Surgical Treatments

  • Complete Tears: Complete tears usually require surgical repair to reattach the torn tendon to the patella.
  • Procedure: Surgery typically involves reattaching the torn tendon using sutures or anchors, and sometimes reinforcing with additional tissues or grafts.


  • Post-Surgery: Initially, the knee may be immobilized in a brace to protect the repair.
  • Physical Therapy: Gradual progression of exercises to restore range of motion, strengthen the quadriceps muscles, and improve knee function.
  • Return to Activity: Full recovery and return to sports or activities can take several months, with gradual reintroduction of activities under the guidance of a healthcare provider.


  • Re-rupture: Risk of the tendon tearing again, especially if rehabilitation guidelines are not followed.
  • Stiffness: Loss of knee range of motion if rehabilitation is inadequate.
  • Infection: Possible risk following surgery, requiring careful wound care and monitoring.

Long-Term Outlook:

  • Prognosis: With appropriate treatment and rehabilitation, many individuals can regain near-normal function of the knee.
  • Follow-Up: Regular follow-up visits with a healthcare provider to monitor progress and address any concerns during recovery.


A quadriceps tendon tear is a serious injury that requires timely diagnosis and appropriate treatment to optimize outcomes. Early medical evaluation, including imaging studies, is crucial for determining the extent of the tear and planning the most effective course of treatment, whether surgical or non-surgical. Rehabilitation plays a vital role in restoring knee function and preventing complications. Consulting with an orthopedic specialist is recommended for personalized evaluation and management.
