Purpose: To evaluate the clinical results of modified peroneal sulcus deepening combined with superior peroneal retinaculum repair in peroneal tendon subluxation treatment.
Methods: From 2016 to 2020, 18 patients with peroneal tendon subluxation were diagnosed and treated; all patients underwent modified peroneal sulcus deepening combined with superior peroneal retinaculum repair. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society ankle-hindfoot (AOFAS-AH) score, and subjective patient satisfaction were evaluated before surgery and during follow-up.
Results: The operative time was 66.44 ± 5.22 min. All patients' surgical incisions showed grade A healing, and there were no complications. All patients were followed up for 24-48 months; no patients were lost to follow-up. At the last follow-up, the VAS and AOFAS-AH scores were significantly improved compared with those pre-operatively (P < 0.05). There was no significant difference in the activity of the 18 patients between pre- and post-operatively, and all patients recovered their normal gait before injury.
Conclusion: Modified fibular groove deepening combined with superior peroneal retinaculum repair for treating peroneal tendon subluxation may be a simple operation with minimal trauma, rapid recovery, and good clinical efficacy.

Intrasheath Peroneal Tendon Subluxation: A Report of Three Cases with Technical Note.

Peroneal intrasheath instability is a painful popping sensation and audible clicking of the lateral ankle. This condition is not commonly reported, and its exact incidence remains unknown. It consists of a transient retromalleolar subluxation of the peroneal tendons, with an abnormal motion of the peroneal tendons relative to each other, with the superior peroneal retinaculum intact.

Background: Approximately 20% of acute ankle sprains progress to chronic lateral ankle instability (CLAI), requiring surgical intervention. When only the anterior talofibular ligament (ATFL) is ruptured, it is controversial whether to perform arthroscopic inferior extensor retinacular (IER) reinforcement.
Purpose: To assess the postoperative outcomes of IER reinforcement versus nonreinforcement in arthroscopic treatment of CLAI with ATFL-only injury.
Efficacy of cold and cryo-preserved nerve allografts with low-dose FK506 for motor nerve regeneration: a preclinical study.

Department of Orthopaedic Surgery, Dankook University Hospital, Dankook University College of Medicine, 201, Manghyang-ro, Dongnam-gu, Cheonan-si, Republic of Korea.
Background: Despite their ability to regenerate as well as autografts, the use of nerve allografts is limited by the need for immunosuppression and the risk of disease transmission. Further, decellularized allografts lacking Schwann cells limit axonal regeneration in long nerve defects. This study evaluated sciatic nerve regeneration in rats implanted with cold- or cryopreserved allografts, and examined the effects of FK506, an immunosuppressant that targets calcineurin function, on motor recovery.

Article Synopsis
- The reconstruction of lower extremity defects with bone or tendon exposure is challenging, and the peroneal artery perforator flap (PAPF) is an effective surgical option for addressing these issues.
- Accurate identification of the peroneal artery's branches and perforators is essential to optimize the flap design and ensure successful transplantation.
- The study highlights the use of preoperative digital subtraction angiography (DSA) and high-frequency ultrasound to visualize and locate anatomically significant branches, aiding in the precision of flap surgery.

Background: Skin graft is frequently used for donor site closure after osteocutaneous fibula free flap (OCFFF) harvest when primary closure is not possible. Partial skin graft loss requiring wound care is a common complication. The purposes of this prospective study were to investigate the perforator anatomy for local propeller or tonearm flap closure and compare the outcomes to those of skin graft closure.
