Abstract:

The aim of this study was to evaluate the results of repair with the peroneus longus tendon of ruptures which developed in the knee extensor mechanism following trauma or total knee arthroplasty. The results were examined of 9 knees of 7 patients who underwent repair of extensor system ligament injury with peroneus longus tendon autograft. The injuries were of the quadriceps tendon only in 2 knees, quadriceps tendon+ medial retinaculum in 4 knees and patellar tendon in 3 knees. The ipsilateral peroneus longus tendon was harvested and repair was made to the ruptured quadriceps tendon, medial retinaculum and patellar tendon. Technically, the peroneus longus tendon was wrapped around the torn quadriceps tendon and closed with the fan-out technique. In tears of the patellar tendon, repair was applied by opening 2 parallel tunnels lengthwise on the patella, then the two ends of the tendon were passed through the separate tunnels in the patella. All the patients operated on for ruptures of the patellar tendon, quadriceps tendon and/or medial retinaculum, returned to their daily life without any support by the 6th month postoperatively. Reconstruction with peroneus longus tendon can be considered a safe and effective method.
