Mandell JC, et al. - This study was performed to offer information on patient demographic characteristics and intra-articular injury seen at arthroscopy after traumatic hip dislocation. In addition, this work entails a description of the literature reported computed tomography (CT) and magnetic resonance findings with arthroscopic correlation and reported arthroscopic treatments performed with complications and outcomes. It was demonstrated in heterogeneously reported previously published cases that a broad spectrum of intra-articular damage amenable to arthroscopic intervention was revealed by arthroscopy. For the detection of intra-articular bodies in all cases, CT was not found to be a sensitive diagnostic modality. Data reported no serious periprocedural adverse events but only 49.7% of patients had reported follow-up data.

Methods

• Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for assessment of arthroscopy after hip dislocation, a systematic review was conducted.
• Researchers searched 3 databases.
• Study screening and data abstraction were performed in duplicate

Results

• This analysis included 31 heterogeneous case series and case reports from the initial search yielding 780 results, including reports of 151 patients who underwent arthroscopy after traumatic hip dislocation.
• Data reported a wide spectrum of intra-articular injury.
• The reported prevalence of labral tears, intra-articular bodies, ligamentum teres injuries, and chondral damage was high.
• Researchers found that CT displayed a sensitivity of 87.3% for detecting intra-articular fragments; however, arthroscopy revealed fragments in 43.3% of patients who had a preoperative CT scan with negative findings for intra-articular fragments.
• For detecting labral tears, a sensitivity of 95.0% was demonstrated by magnetic resonance.
• Findings did not demonstrate any major complications directly attributed to arthroscopic surgery.
• In addition, data revealed osteoarthritis in 4.0% and avascular necrosis in 2.7% of a total of 75 of 151 patients followed up for a median of 2 years after surgery.
