Main indications for peroneal tendoscopy and their treatment
| Injury site | Pathology | Proposed treatment |
|---|---|---|
| Zone A | Peroneal tenosynovitis | Tenosynovectomy (shaver) |
| Peroneal tendinopathy | Tendon debridement and excision of the area of tendinosis (shaver, mini-open repair) | |
| Hypertrophy of muscle belly (low-lying peroneus brevis muscle belly) | Resection of the distal muscle fibers (shaver) | |
| Partial tendon tears, longitudinal ruptures | Debridement (shaver, mini-open repair | |
| Postsurgery or postfracture adhesions | Debridement (shaver) | |
| Bony prominences at the posteriori aspect of the fibula (tendon sliding channel) | Excision (burr) | |
| Tendon subluxation (instability) in shallow fibular groove | Groove deepening (burr) | |
| Peroneal impingement and subluxation in the presence of accessory peroneal muscle (peroneus quartus) | Peroneus quartus excision (shaver; mini-open) | |
| Peroneal adhesion-snapping between tendons and their sheath for thickened vinculum | Vinculum release (shaver) | |
| Zone B | Peroneal impingement for hypertrophic or prominent peroneal tubercle | Excision-flattening (burr) |
| Stenosis or degenerative tearing | Resection of the impinging synovium, release of the inferior retinaculum from the peroneal tubercle (shaver; mini-open) | |
| Degenerative tendinopathy/tendon hypertrophy | Mini-open repair |
