Chronic tibialis anterior tendon tear treated with an Achilles tendon allograft technique.

Tibialis anterior tendon tear is an uncommon injury. Nontraumatic or degenerative tears are usually seen in the avascular zone of the tendon. Treatment can be conservative or surgical. Conservative treatment is adequate for low-demand older patients. For active patients, surgical treatment can be challenging for the surgeon because after debridement of degenerative tissue, a gap may be formed that can make side-to-side suture impossible. The authors present allograft Achilles tendon insertion for reconstruction of chronic degenerative tears. Using Achilles tendon allograft has the advantage of bone-to-bone fixation, allowing rapid incorporation and earlier full weight bearing.
