Arthroscopic Treatment of Acetabular Condral Defects Using BST-CarGel

OBJECTIVES: The purpose of this study is to retrospectively analyze prospectively collected data to evaluate the shortterm outcome of patients treated arthroscopically with BSTCarGel for acetabular chondral defect. METHODS: Between November 2014 and December 2015, 22 patients (23 hips) underwent hip arthroscopy for correction of femoroacetabular impingement, labral repair and treatment of acetabular chondral defect. Patient evaluations included general assessment with iHOT33 questionnaire at the time of preoperative consultation, and the postoperative followup at 2 weeks, 6 weeks, 3 months, 6 months, 1 year and 2 year marks. Additionally, preoperative and postoperative plain radiographs and MRarthrogram scans were analyzed for evaluation. RESULTS: 22 patients (23 hips) have been evaluated with a mean age of 33.34 years at the time of the index operation. There were 16 males (17 hips, mean age of 32.00) and 6 female (6 hips, mean age of 37.15). The average followup was 1 year, with a minimum followup of 6 months. The preoperative iHOT33 score was 47.1, the 6 months postoperative score was 54.8, and the 12 month postoperative score was 63.7 (p < 0.05) MRIArthrograms demonstrated a decrease in the size of the chondral defects. No significant adverse outcomes have been reported. CONCLUSION: Arthroscopic treatment of chondral acetabular defect with BSTCarGel demonstrates encouraging signs of cartilage healing as shown on MRarthrograms, without significant adverse outcomes. Longer followup is required to determine if this improvement is maintained.
