Immobilization

• A moderate ankle sprain may be treated by immobilizing the ankle and foot in a walking boot for two to six weeks. This allows the peroneal tendon to heal. For minor sprains, the physician may treat the tendon by having the patient wear a ankle brace or something to support the arch of the foot.
  
  

Medication

• To reduce swelling and ease pain, a physician may suggest taking over-the-counter anti-inflammatory medication such as ibuprofen. He may also prescribe an anti-inflammatory for more severe cases.
  
  

Physical Therapy

• The goal of physical therapy treatment is to strengthen and stretch the peroneal tendon. Physical therapy also improves function and coordination of the ankle. This treatment is done for moderate injuries as well as after surgery.
  
  

Tendon Release

• A tendon release is a surgical procedure to remove inflamed tissue from around the tendon. The surgeon opens the sheath that surrounds the tendon and removes the inflamed tissue. The gap in the sheath is left to build up scar tissue. A walking boot may be worn for two to six weeks after surgery followed by physical therapy to restore function and build strength in the ankle.
  
  

Tendon Repair

• A tendon repair is done when the peroneal tendon is torn down the middle of the tendon. The tendon may be sutured together or if the tear is less than one-third of the width of the tendon, the surgeon may remove the portion that is torn. After surgery, the patient will typically have the ankle and foot immobilized. Physical therapy may be ordered after the cast or walking boot is removed to help strengthen the muscles, tendons and ligaments in the ankle.
  
  

Retinaculum Repair

• The retinaculum is what covers the sheath around the peroneal tendons in the ankle. To repair a tear in the retinaculum, the surgeon will make a trough in the fibula bone. He then pulls the torn piece into the trough and sutures it in place. The foot is immobilized for two to six weeks in a splint or cast. Physical therapy may be ordered by the physician after the splint or cast is removed to strengthen and restore function to the ankle.
