Recurrent peroneal tendon dislocation is a rare and often underrecognized condition. It may result from acute injuries, more commonly seen in athletes, or from untreated ankle sprains leading to chronic ankle instability. The aim of this study is to retrospectively evaluate short- and medium-term functional outcomes of the surgical technique involving deepening of the retromalleolar groove for the management of recurrent peroneal tendon dislocation. Nine patients, one of whom had bilateral dislocation, were enrolled in this study. The study group consisted of six males and three females, with a mean age of 31.2 years. CT scans were used to measure the depth of the neo-grooves, while the EFAS score (European Foot and Ankle Society Score) and AOFAS score (American Orthopedic Foot and Ankle Score) were used to assess functional results. The medium follow-up period was 4.8 years. CT scan data revealed a mean increase of 4.69 mm in the depth of the neo-retromalleolar groove. AOFAS scores improved from a mean preoperative value of 74.4 to 86.9 after surgery, and EFAS scores increased from a mean preoperative score of 19.7 to 31. Statistical analysis of clinical scores yielded significant results with a p-value < 0.005. All patients returned to their previous sports activities within an average time of 7.7 months, reporting no pain or limitations. There were no recurrences observed. The retromalleolar groove deepening technique demonstrated excellent results in the treatment of recurrent peroneal tendon dislocation, evidenced by significant improvements in clinical scores, functional recovery, successful return to sports, and high patient satisfaction.

Abstract

Recurrent peroneal tendon dislocation is a rare and often underrecognized condition. It may result from acute injuries, more commonly seen in athletes, or from untreated ankle sprains leading to chronic ankle instability. The aim of this study is to retrospectively evaluate short- and medium-term functional outcomes of the surgical technique involving deepening of the retromalleolar groove for the management of recurrent peroneal tendon dislocation. Nine patients, one of whom had bilateral dislocation, were enrolled in this study. The study group consisted of six males and three females, with a mean age of 31.2 years. CT scans were used to measure the depth of the neo-grooves, while the EFAS score (European Foot and Ankle Society Score) and AOFAS score (American Orthopedic Foot and Ankle Score) were used to assess functional results. The medium follow-up period was 4.8 years. CT scan data revealed a mean increase of 4.69 mm in the depth of the neo-retromalleolar groove. AOFAS scores improved from a mean preoperative value of 74.4 to 86.9 after surgery, and EFAS scores increased from a mean preoperative score of 19.7 to 31. Statistical analysis of clinical scores yielded significant results with a p-value < 0.005. All patients returned to their previous sports activities within an average time of 7.7 months, reporting no pain or limitations. There were no recurrences observed. The retromalleolar groove deepening technique demonstrated excellent results in the treatment of recurrent peroneal tendon dislocation, evidenced by significant improvements in clinical scores, functional recovery, successful return to sports, and high patient satisfaction.
