Pearls and Pitfalls of the In-Office Needle Arthroscopy Technique
| Pearls | Pitfalls |
|---|---|
| Create portals sites with stab incisions only though skin and follow with blunt dissection | Improper placement of posterolateral portal may place the sural nerve at increased risk of injury |
| Direct the instruments toward the lateral border of third metatarsal while placing the initial portal | Iatrogenic injury to medial neurovascular bundle during instrument insertion may occur if inserting instruments too medially |
| Diligent initial debridement of fatty tissue with direct visualization of instrument and triangulation (place instrument and camera at 90° to facilitate localization and visualization) | Without establishing adequate visualization, debridement may lead to iatrogenic injury |
| Debridement of hypertrophied intermalleolar ligament if the case of posterior ankle impingement warrants it | In cases of posterior ankle impingement, failure to debride intermalleolar ligament may result in residual pain and mechanical symptoms |
| Identification of the flexor hallucis longus tendon using passive flexion/extension of the hallux | Incorrectly identifying the flexor digitorum longus or posterior tibial tendons as the flexor hallucis longus tendon |
| Maintaining awareness of the full working length of shaver while working near the flexor hallucis longus tendon | Damaging the flexor hallucis longus tendon due to length of shaver while working on other structures |
| Calcaneal distraction and ankle dorsiflexion to facilitate entry into the posterior tibiotalar joint | Damaging articular cartilage from aggressive attempts to pass instruments into joint space |
| Inserting a probe into the subtalar joint to assess range of motion in nonosseous coalition followed by resection | Attempting to resect large coalitions or osseous coalitions which are not amenable to arthroscopic treatment |
