Abstract
This is a retrospective study of 46 patients who underwent arthroscopic glenoid labral
debridement from June 1988 to June 1990. All patients complained of pain in the involved
shoulder and all were active in sports involving overhead use of the shoulder, including
30 baseball players (16 professional, 14 collegiate/high school). The average age
was 22 years (range 16 to 45) and the average follow-up was 2.7 years (range 18 to
50 months). At operation, 35 patients had posterior glenoid lesions, 9 had anterior-superior
lesions, and 2 had anterior-inferior lesions. The posterior lesions were further divided
into those that involved a horizontal flap tear (n = 19), and those that involved
fraying (n = 16). Overall, at an average of 31 months follow-up, 54% (25 of 46) of
patients had good to excellent results. Professional baseball players had a statistically
significant enhanced outcome with 75% (12 of 16) good-excellent compared with the
remaining nonprofessional group, with 43% (13 of 30) good-excellent results. Outcome
did not correlate with shoulder laxity, labral lesion location, mechanism of injury,
or the presence of a rotator cuff lesion. Conclusions: Arthroscopic debridement of
glenoid labral lesions does not yield consistent long-term results. Aggressive, supervised
physical therapy in highly motivated individuals may be the most important factors
in influencing outcome in patients having arthroscopic labral debridement in the absence
of overt shoulder instability.
