Knotless Tendoscopic Peroneal Retinaculum Repair Technique for Recurrent Peroneal Tendon Dislocation.

ABSTRACT: Peroneal tendon dislocation (PTD) is sometimes diagnosed as a sports-related injury, of which many cases lead to recurrent PTD (RPTD). Superior retinaculum repair is the major operative treatment of RPTD. The technique described herein comprises 8 steps: (1) Standard tendoscopic examination, (2) debridement of the pseudo-pouch base, (3) first anchor insertion, (4) suture relay, (5) second anchor insertion and suture relay, (6) third anchor insertion and suture relay, (7) suture tightening, and (8) suture bridge. Although this tendoscopic peroneal retinaculum repair technique is complicated, expensive, and requires a longer operation time, it incorporates a double-row suture bridge. Therefore, it has a wider contact surface between the superior retinaculum repair and fibula bone and tighter fixation than does a single-row technique. Moreover, our technique is knotless and thereby avoids knot-related complications. Tendoscopy has additional advantages in terms of less postoperative pain, fewer complications, and better cosmesis. In conclusion, this knotless tendoscopic peroneal retinaculum repair technique for RPTD is a patient-friendly surgery compared with previous procedures.

Project description:The peroneus muscles, consisting of the peroneus longus (PL) and peroneus brevis (PB) tendons, are vulnerable to injury at anatomically specific sites or within tendon sheaths. Peroneal tendon dislocation (PTD) is often misdiagnosed as a lateral ankle sprain as it occurs at a lower frequency than a lateral ankle sprain. Anatomical variations in the retromalleolar groove, soft tissue overstuffing, and presence of accessory peroneal muscles contribute to the etiology of PTD. PTD has been classified into four types based on injury patterns involving the superior peroneal retinaculum (SPR) and fibrocartilaginous ridge. Diagnosis involves recognizing tender points and using imaging including magnetic resonance imaging (MRI) and ultrasonography. Conservative treatments, including below-knee plaster casts, have varying success rates, and some patients progress to recurrent PTD (RPTD), prompting consideration of surgical interventions. Diagnosis is easy in patients with RPTD who can reproduce the dislocation by themselves; however, in many cases, this is not possible. In such cases, ultrasonography after intrasheath injection is effective in confirming the presence of a pseudo-pouch. RPTD can be diagnosed if a pseudo-pouch is identified during ultrasonography. Surgical approaches such as osteotomy, soft tissue procedures, and groove deepening techniques are used to stabilize the peroneal tendons. Soft tissue procedures, especially SPR reattachment, have emerged as a preferred option, demonstrating outcomes comparable to those of osteotomy, with fewer complications. Intrasheath subluxation, a unique PTD subtype, is diagnosed using ultrasonography. In this type of subluxation, no damage to the SPR is observed, and the positions of the PL and PB tendons are interchanged. Surgical intervention may involve excision of the synovium and SPR repair. In cases of PTD complicated by a longitudinal rupture of the PB tendon, suturing of the torn area or tubularization of the remaining tendon for partial resection of the degenerated tendon can be performed. The purpose of this article is to describe the methods for diagnoses and management of PTD.
