Medial, lateral arthroscopy may be safe, effective for multidirectional ankle instability
Published results showed combined medial and lateral arthroscopic repair may be a safe and effective treatment for multidirectional ankle instability.
Researchers evaluated 30 ankles in 29 patients with multidirectional instability who underwent ankle arthroscopy with medial and lateral repair between January 2018 and January 2020. Researchers considered function assessed through the American Orthopaedic Foot & Ankle Society Hindfoot Score as the primary outcome, while secondary outcomes included pain using the VAS and complications. Researchers performed assessments preoperatively and at 5-month postoperative follow-up.
Results showed patients had a statistically significant increase in AOFAS Hindfoot Score from a mean of 49.7 at baseline to 91.9 at last assessment. Researchers also noted patients had a significant progression in VAS.
Although 16% of patients experienced complications, most were minor and self-limited, according to results. Researchers found 53.3% of patients had associated procedures, and adjuvant procedures included microfracture for an osteochondral lesion of the talus in 20% of patients, peroneal tendoscopy in 10% of patients, lateral internal bracing in 10% of patients and syndesmosis fixation in 6% of patients.
“In conclusion, multidirectional instability still has a long debate ahead and many aspects to be tested. Its importance and treatment necessity are increasingly gaining attention as the notion that not every ankle behaves the same,” the authors wrote. “Results of this study, grounded in its good results and low complication rate, may establish a strong base for potential case-control studies and clinical trials in a near future.”
