  • Title: Variability of Arthroscopy Case Volume in Orthopaedic Surgery Residency.
    Author: Gil JA, Waryasz GR, Owens BD, Daniels AH.
    Journal: Arthroscopy; 2016 May; 32(5):892-7. PubMed ID: 26993670.
    Abstract:
    PURPOSE: To examine orthopaedic surgery case logs for arthroscopy case volume during residency training and to evaluate trends in case volume and variability over time. METHODS: Publicly available Accreditation Council for Graduate Medical Education surgical case logs from 2007 to 2013 for orthopaedic surgery residency were assessed for variability and case volume trends in shoulder, elbow, wrist, hip, knee, and ankle arthroscopy. The national average number of procedures performed in each arthroscopy category reported was directly compared from 2009 to 2013. The 10th and 90th percentile arthroscopy case volume was compared between 2007 and 2013 for shoulder and knee arthroscopy procedures. Subsequently, the difference between the 10th and 90th percentile arthroscopy case volume in each category in 2007 was compared with the difference between the 10th and 90th percentile arthroscopy case volume in each category in 2013. RESULTS: From 2007 to 2013, shoulder arthroscopy procedures performed per resident increased by 43.1% (P = .0001); elbow arthroscopy procedures increased by 28.0% (P = .00612); wrist arthroscopy procedures increased by 8.6% (P = .05); hip arthroscopy procedures, which were first reported in 2012, increased by 588.9%; knee arthroscopy procedures increased by 8.5% (P = .0435); ankle arthroscopy increased by 27.6% (P = .00149). The difference in knee and shoulder arthroscopy volume between residents in the 10th and 90th percentile in 2007 and residents in the 10th and 90th percentile in 2013 was not significant (P > .05). There was a 3.66-fold difference in knee arthroscopy volume between residents in the 10th and 90th percentile in 2007, whereas the difference was 3.36-fold in 2013 (P = .70). There was a 5.86-fold difference in shoulder arthroscopy case volume between residents in the 10th and 90th percentile in 2007, whereas the difference was 4.96-fold in 2013 (P = .29). CONCLUSIONS: The volume of arthroscopy cases performed by graduating orthopaedic surgery residents has significantly increased over time. There continues to be substantial variability in knee and shoulder arthroscopy case volume between residents in the 10th and 90th percentile. CLINICAL RELEVANCE: Variability in residency training is notable and may affect knowledge, skill, and practice patterns of surgeons.
