[Objective] To explore the clinical outcomes of hip arthroscopy for mere pincer- type femoroacetabular impingement. [Methods] A retrospective study was conducted on a total of 24 patients who underwent hip arthroscopy for mere pincer-type femoroacetab- ular impingement in our department from June 2017 to July 2019. The patients included 14 females and 10 males, aged (33.52±11.42) years on average, and received arthroscopic acetabuloplasty for the pincer-type femoroacetabular impingement. [Results] All the patients were successfully operated on under arthroscope, and were confirmed to have pincer-type impingement only without femoral head- neck junction cam-like osteophytes. All patients got incisions healing primarily without complications such as intraarticular infection, necrosis of femoral head, deep vein embolism and nerve injury of lower limb. All the 24 patients were followed up for more than 12 months. The flex- ion, adduction and internal rotation (FADIR) test, as well as the flexion, abduction and external rotation (FABER) tests significantly im- proved in the 24 patients at 6 months postoperatively and at the last follow-up compared with those preoperatively (P＜0.05) . In addition, the VAS scores significantly decreased (P＜0.05) , while the mHHS and iHOT-12 scores significantly increased postoperatively compared with those before operation (P＜0.05) . Radiographically, the lateral center edge angle (LCEA) significantly reduced (P＜0.05) , the acetabu- lar index (AI) increased significantly (P＜0.05) , whereas the positive rates of cross sign and posterior wall sign significantly decreased at 6 months postoperatively and at the latest follow-up compared with those preoperatively (P＜0.05) . However, there were no significant chang- es in terms of T?nnis osteoarthritis grades and the positive rate of deep acetabular sign at 6 months postoperatively, or at the last follow-up compared with that preoperatively (P＞0.05) . [Conclusion] Acetabuloplasty under hip arthroscopy does significantly relieve the pain, im- prove function and achieve sound short-term clinical outcomes for mere pincer-type femoroacetabular impingement.
