Key result
Hip arthroscopies by high-volume surgeons are linked to a lower risk of subsequent surgery.
Why the study?
Does higher surgeon career volume reduce the risk of subsequent surgery after primary hip arthroscopy?
Does higher surgeon career volume reduce the risk of subsequent surgery after primary hip arthroscopy?
Surgeons performing hip arthroscopy reach a learning curve threshold at 519 cases, after which the risk of subsequent surgery is significantly reduced.
Supports volume-outcome link for hip arthroscopy; hypothesis-generating and requires prospective validation before changing practice.
Stratum specific likelihood ratio analysis of 8,041 hip arthroscopies defined 4 strata of surgeon career volume associated with significantly different risks of subsequent surgery after primary hip arthroscopy. Cases performed by surgeons with career volumes over 519 had significantly lower risk of subsequent hip surgery than those performed by lower-volume surgeons.
