Abstract:
Objective:To investigate the early effect of repairing acetabular cartilage delamination with absorbable anchor under hip arthroscopy compared with conventional non-intervention.Methods:Retrospective cohort study was adopted. There were 24 Femoroacetabular Impingment (FAI) patients with acetabular cartilage delamination (ACD) receiving hip arthroscopy surgery in Peking University Third Hospital from May 2021 to August 2021. There were 14 males and 10 females with an average age of 36.3±7.2 years (range 23-53 years). There were 12 patients receiving acetabular cartilage repair with absorbable anchor (absorbable anchor group), and 12 patients in non-intervention group. The X-ray film indicators, α angle, lateral center edge angle (LCEA) and MRI measurement (acetabular cartilage gap, CG) were compared between the two groups. The pre- and post-operative hip functions were assessed by modified Harris Hip Score (mHHS), 12-item international hip outcome tool (iHOT12), hip outcome score-activities of daily living subscale (HOS-ADL), and hip outcome score-sports subscale (HOS-SS), along with visual analogue scale (VAS). The complications (infection, lower extremity deep venous thrombosis) were followed up, as well as the revisional hip arthroscopy surgery and total hip replacement surgery.Results:A total of 24 patients were followed up for 12.0±1.2 months (range 10-14 months). There was no significant difference between the two groups for age, BMI, and symptom onset time ( P>0.05). There was no significant difference between the two groups for the pre-operative α angle, LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, and VAS scores ( P>0.05). At the last follow-up, there was no significant difference between the two groups for the α angle, LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, VAS and satisfaction ( P>0.05). In the absorbable anchor group, the α angle was 47.2°±2.6° vs. 63.4°±3.3°, CG was 3.0±0.7 mm vs. 3.3±0.6 mm; mHHS was 73.6±16.0 vs. 57.7±15.4; iHOT12 was 67.6±22.5 vs. 50.6±15.0 after and before the surgery, with significant improvement ( P<0.05). As for the non-intervention group, there was significant decrease of post-operative α angle of 47.4°±2.6° compared to the pre-operative angle of 58.4°±8.1° ( P<0.05). There was no significant difference in LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, and VAS scores before and after the surgery in non-intervention group comparison ( P>0.05). No complications, revision hip arthroscopy surgery or total hip replacement surgery occurred during the follow up. Conclusion:Good effect was yielded for absorbable anchor repairing acetabular cartilage delamination under hip arthroscopy, without additional risk of complications or revision surgery.
