Arthroscopic findings associated with the unstable ankle

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Arthroscopy

Background:

• Chronic ankle instability affects a significant patient population, often requiring surgical intervention.
• Arthroscopic techniques offer a minimally invasive approach to address intra-articular pathology.
• Previous research indicates varying incidences of chondral injuries in unstable ankles.

Purpose of the Study:

• To evaluate the outcomes of arthroscopic surgery for chronic ankle instability.
• To identify common intra-articular abnormalities associated with chronic ankle instability.
• To assess the correlation between specific pathologies and surgical results.

Main Methods:

• Retrospective review of 55 ankles in 54 patients undergoing arthroscopic surgery for chronic ankle instability.
• Analysis of patient charts, imaging, operative reports, and surgical videos.
• Postoperative questionnaires assessing patient outcomes and satisfaction.

Main Results:

• 96% of patients reported excellent or good outcomes following arthroscopic surgery.
• 93% of ankles exhibited intra-articular abnormalities, including synovitis, loose bodies, and osteochondral lesions.
• A 25% incidence of chondral injuries was observed, differing from prior studies.
• Worker's compensation status was associated with a lower incidence of excellent results due to persistent pain.

Conclusions:

• Arthroscopic surgery is a highly effective treatment for chronic ankle instability, yielding excellent or good results in most cases.
• A wide range of intra-articular pathologies are frequently encountered and addressed during arthroscopic stabilization.
• Surgical outcomes are generally favorable, though factors like worker's compensation status may influence patient-reported pain levels.
