Staged patellar tendon reconstruction using doubled bone-patellar tendon-bone allograft for infected patellar tendon rupture: a rare case report of three years follow-up.

Our technique introduced in this specific case is a relatively simple method to reconstruct chronic patellar tendon defects with limited incision exposing only the patellar tendon areas. We expect it can be less invasively performed on patients who have a soft tissue problem and cannot have extensive surgery.
