Diagnosis Code: S86.811A

The patellar tendon is a strong, fibrous cord that connects the bottom of your kneecap (patella) to the top of your shinbone (tibia). It plays a crucial role in extending your knee, allowing you to kick, jump, and walk. A patellar tendon tear occurs when this tendon is partially or completely ruptured, disrupting the connection between the kneecap and shinbone.  

How Does it Occur?

Patellar tendon tears often happen due to sudden forceful contractions of the thigh muscles or direct impact to the knee. Common causes include:  

• Sports Injuries: High-impact activities like basketball and volleyball, where jumping and landing forcefully are common, can lead to tears.  
• Traumatic Injuries: Direct impact to the knee, such as from a fall or a direct blow during contact sports, can also cause tears.  

Treatment

Treatment for a patellar tendon tear depends on the severity of the tear, the individual’s age, and their activity level.  

Conservative Treatment

For partial tears or in cases where surgery is not suitable, non-surgical options may be considered:

• Immobilization: Using a brace or cast to keep the knee straight and allow the tendon to heal.  
• Crutches: To avoid putting weight on the injured leg.  
• Physical Therapy: Exercises to strengthen the muscles around the knee and improve range of motion.  

Surgical Treatment

Complete tears or severe partial tears often require surgery to repair the tendon:

• Open Surgery: The surgeon makes an incision to access the torn tendon and stitches it back together.  
• Minimally Invasive Surgery: Small incisions are used, and the repair is performed with specialized instruments.  

Recovery

Recovery time varies depending on the type of treatment and the individual’s overall health.  

• Non-Surgical Recovery: With proper immobilization and physical therapy, partial tears may heal within several weeks.  
• Post-Surgical Recovery: Recovery from surgery typically involves:
  1. Immediate Post-Op: Keeping the leg immobilized in a brace or cast and using crutches.  
  2. Rehabilitation: Gradually increasing weight-bearing and participating in physical therapy to regain strength and range of motion. This can take several months.  
  3. Return to Activity: Full recovery and return to sports or strenuous activities may take 6 months to a year or longer.
