Magnetic resonance imagination of the peroneus longus tendon after anterior cruciate ligament reconstruction

Abstract

Several studies report that tendons can regenerate after harvesting. These studies have been performed especially in patellar and hamstring tendons. At our institution, 10 cm length of full thickness peroneus longus tendon has been harvested to reconstruct torn anterior cruciate ligament since 1997 as a different graft source. The aim of this study was to investigate whether the peroneus longus tendon used the anterior cruciate ligament reconstruction has a regeneration potential or not. Twelve patients, who had originally undergone harvesting of the peroneus longus tendon for the primary surgery of the anterior cruciate ligament reconstruction, underwent magnetic resonance imaging (MRI). Images of both legs were acquired simultaneously with the use of the scanner's extremity coil, as we aimed to compare harvested peroneus longus tendon with the other leg's peroneus longus tendon (healthy side) for evaluation of the regeneration potential. The average age of the patients was 31 years. There were eight right and four left legs. The average time interval was 52 months between ligament surgery and MRI. In all patients, a varying amount of the regeneration of the peroneus longus tendon was seen on the MRI images. Although the extent of PLT regeneration in proximal sections seemed better than in mid- and distal sections, there was no statistical difference between sections (P = 0.130). These data show that the peroneus longus tendon has a regeneration potential after harvesting for anterior cruciate ligament reconstruction.

“…Similarly, another study reported that PLT could regenerate after harvesting. 14 In 12 patients who had undergone full-thickness PLT harvesting, a varying amount of regeneration was seen on MRI. The mean percentages of regeneration were 59.2%, 49.9%, and 44.5% in the proximal, middle, and distal sections, respectively.…”

Peroneus Longus Tendon Regeneration after Anterior Cruciate Ligament Reconstruction with Magnetic Resonance Imaging Evaluation

“…Peroneus tendons are an alternative to reconstructing ligaments to prevent morbidity from donor sites in another tendon [5]. Kerimoglu studied 12 patients who underwent ACL reconstruction using peroneus longus tendon grafts with follow-up ranging from 18 to 96 months using MRI and found that there was a regeneration of peroneus longus tendons and there was no disturbance in ankle function and exercise [11].…”

“…The purpose of ACL reconstruction is to restore knee stability, relieve pain and instability symptoms, and return the patient to daily activities [1]. There are several graft choices used in ACL reconstruction, one of which is the peroneus longus tendon graft [2]. Peroneus longus autograft is an effective and safe graft as an alternative to ACL reconstruction [3].…”

“…Regeneration in gracilis and semitendinosus tendons also occurs distally from the joint line [9]. Magnetic resonance imagery (MRI) can be a parameter to assess the regeneration of peroneus longus tendon grafts in ACL reconstruction [10], [11]. Accordingly, a deeper study of the regeneration of the peroneus longus graft in ACL reconstruction is needed.…”
