Dashes indicate intervals for which ΔMean could not be calculated due to unavailability of data at either time point

UCLA University of California—Los Angeles Shoulder Score, SANE Single Assessment Numeric Evaluation, SF-12 Short Form Health Survey-12, MCID minimal clinically important difference, n summed pre-operative enrollment for all studies reporting respective measure

^aP < .05 utilized for all statistical comparisons

^bThree-month data utilized in place of 6-week data. (Three-month data was the earliest available for Walch–Duplay.)
