TI  - Outcomes in Patients with Global Pincer Versus Focal Pincer Femoroacetabular 
      Impingement Treated with Hip Arthroscopy: A Retrospective Study with a Minimum 
      2-Year Follow-Up.

AB  - OBJECTIVE: Global pincer is a relatively rare form of pincer deformity and is 
      typically associated with technical challenges during surgery. So far, 
      controversy remains whether patients with global pincer have equivalent surgical 
      outcomes compared to patients with focal pincer. This study compares the clinical 
      outcomes of arthroscopic treatment between patients with global pincer 
      femoroacetabular impingement (FAI) and focal pincer FAI in the Chinese 
      population. METHODS: Data were retrospectively collected from patients with 
      global and focal pincer FAI who underwent hip arthroscopy with a minimum two-year 
      follow-up between April 2016 and December 2018. Radiographic measurements, 
      arthroscopic procedures, preoperative and postoperative patient-reported outcomes 
      (PROs) including modified Harris hip score (mHHS), hip outcome score-activities 
      of daily living (HOS-ADL), international hip outcome tool-12 (iHOT-12), and 
      visual analogue scale (VAS) scores, rates of revision surgery and conversion to 
      total hip arthroplasty (THA) were recorded. Achievement of minimal clinically 
      important difference (MCID) and patient acceptable symptomatic state (PASS) was 
      compared for the VAS, mHHS, HOS-ADL, and iHOT-12 scores between groups. RESULTS: 
      The total of 33 and 167 patients were included in the global and focal group, 
      respectively. There were no intergroup differences in age, gender, body mass 
      index or follow-up times. Lateral center-edge angle (LCEA) was reduced in both 
      groups postoperatively. Both groups demonstrated significant improvements in PROs 
      compared with preoperative levels at the final follow-up. The preoperative scores 
      showed significant differences in terms of mHHS (60.34 vs 62.90, P = 0.031) and 
      HOS-ADL (61.45 vs 64.74, P = 0.022) scores between two groups, and the 
      improvement of HOS-ADL score was significantly higher in global group 
      (P = 0.027). However, the postoperative scores, including VAS, mHHS, HOS-ADL, and 
      iHOT-12 scores, showed no significant differences between two groups. And there 
      were no significant differences in the rate of meeting the PASS and MCID between 
      groups. One (3.0%) in the global group and six (3.6%) patients in the focal group 
      underwent revision arthroscopy respectively, with no significant difference 
      (P = 0.876). There were no conversions to THA in both groups. CONCLUSIONS: 
      Arthroscopic management of global pincer FAI can achieve excellent functional 
      scores at minimum 2-year follow-up. The outcomes were similar to focal pincer FAI 
      patients with a low rate of secondary procedure.
