Tendoscopic Treatment of Peroneal Intrasheath Subluxation: A New Subgroup With Superior Peroneal Retinaculum Injury

“…The tendoscopic treatment of snapping peroneal tendons has been reported for chronic and intrasheath subluxation. 21,22,32,40,42 The tendoscopic technique is a simple, safe, and reproducible procedure; furthermore, it preserves the SPR in case of intrasheath subluxation with intact SPR. Excision of a PQ or LLPB muscle, groove deepening, and tendon tears can all be managed tendoscopically.…”

Endoscopic Resection of Peroneus Quartus

“…In cases in which the visual field is obscured by the crowding effect of the peroneus quartus or low-lying muscle fibers in the proximal portion of the superior peroneal tunnel, an extra-sheath peroneal tendoscopy can be performed. 12 The muscle is debulked before the surgeon can gain access to the superior peroneal tunnel.…”

“…9 Endoscopic resection of the peroneus quartus has also been reported. 6,11,12 The purpose of this Technical Note was to describe the details of endoscopic resection of the peroneus quartus. This endoscopic approach is indicated for the symptomatic peroneus quartus muscle.…”

Peroneal Tendoscopic Debridement and Endoscopic Groove Deepening in the Prone Position

“…Some orthopaedic surgeons recommend elective resection of a low-lying peroneus brevis muscle belly and peroneus quartus muscle in the retro-malleolar groove, which will allow improved gliding ability of the peroneus brevis and longus tendons as they course around the ankle. This will help to avoid or limit peroneal tendon injury around the ankle 8, 9…”
