HypothesisChondrolysis has been observed after shoulder arthroscopy and results in severe glenohumeral complications.Materials And MethodsTwenty three cases of post-arthroscopic glenohumeral chondrolysis, occurring between 2005-2006, are reported following a variety of arthroscopic shoulder procedures. Presenting complaints, signs and symptoms, associated operative findings, and potential etiological factors are reviewed. Management options are summarized.ResultsOf the 23 cases of chondrolysis identified in our practice over a two year period, 14 occurred in patients following labral repair using a bioabsorbable device. Seventeen of the 23 patients used a high volume intra-articular pain pump for 48 hours after surgery. Seven of the 23 cases had documented use of a thermal probe. Four cases occurred in shoulders with no reported use of fixation anchors, pain pumps, or thermal probes. All cases had at least a 20 cc intra-articular bolus injection of 0.25% bupivicaine with epinephrine.DiscussionThis case series identifies several common factors that could be responsible for post-arthroscopic glenohumeral chondrolysis. No single mechanism can be implicated based on the results of this study. Although strong concerns are raised over the use of intra-articular local anesthetics, glenohumeral chondrolysis appears to be an unfortunate convergence of multiple factors that may initiate rapid dissolution of articular cartilage and degenerative changes.ConclusionChondrolysis is a devastating complication of arthroscopic shoulder surgery that can result in long-term disabling consequences. Further research is required to specifically identify causative factors. Until this is a available, we strongly advise against the use of large doses of intra-articular placement of local anesthetics.
