Reattachment of the SPR Versus the Bone Block Procedure for Recurrent Peroneal Tendon Dislocation
Study Details
Study Description
Brief Summary
Clinical outcomes between reattachment of the superior peroneal retinaculum (SPR) and the bone block procedure were compared in this study to elucidate which procedure was safer and more effective.

Detailed Description
From 2012 to 2016, 25 patients with recurrent peroneal tendon dislocation underwent the bone block procedure(group A), and another 22 patients underwent reattachment of the SPR (group B). American Orthopaedic Foot and Ankle society (AOFAS) ankle-hindfoot score, Ankle Activity Score (AAS), time to return to sports activity, rate of return to sports level, range of motion (ROM) of the ankle, rate of recurrence, and overall patient satisfaction were collected to evaluate outcomes between the two groups.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Bone block procedure patients with recurrent peroneal tendon dislocation underwent the bone block procedure |
Procedure: bone block procedure
a 20 × 15 × 3 mm3 bone block was cut from the lateral malleolus, rotated backwards 45°, and sutured back to the periosteum of the lateral malleolus using non-absorbable sutures.

| Reattachment of the superior peroneal retinaculum patients with recurrent peroneal tendon dislocation underwent reattachment of the superior peroneal retinaculum |
Procedure: Reattachment of the superior peroneal retinaculum
two suture anchors (Mini Quickanchor,DePuy Mitek) were inserted into the postero-lateral ridge of the lateral malleolus without damaging the cartilaginous ridge, after which the SPR was reattached to the lateral malleolus with the anchored suture. The inner layer of the false pouch was incised, and the outer layer (periosteum) was sutured with the SPR in a pants-over-vest style.

Outcome Measures
Primary Outcome Measures
- AOFAS [2 years after operation]
The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score combines subjective scores of pain and function provided by the patient with objective scores based on the surgeon's physical examination of the patient (to assess sagittal motion, hindfoot motion, ankle-hindfoot stability and alignment of the ankle-hindfoot). The scale includes nine items that can be divided into three subscales (pain, function and alignment). The minimum and maximum values of AOFAS are 100 and 0, respectively. And higher scores mean a better outcome.
Secondary Outcome Measures
- VAS [2 years after operation]
The Visual Analogue Scale (VAS) is designed to present to the respondent a rating scale with minimum constraints. Respondents mark the location on the 10-centimeter line corresponding to the amount of pain they experienced. This gives them the greatest freedom to choose their pain's exact intensity. It also gives the maximum opportunity for each respondent to express a personal response style. The minimum and maximum values of VAS are 10 and 0, respectively. And higher scores mean a worse outcome.
- time to return to sports activity [up to 2 years]
time to return to sports activity after surgery at each group
