Arthroscopic Knot Removal for Failed Superior Labrum Anterior-Posterior Repair Secondary to Knot-Induced Pain.

Background:Studies on failed superior labrum anterior-posterior (SLAP) repair are increasing. However, the number of reports on treatment options for failed SLAP repair remains quite low, and the clinical results vary between different study groups.Purpose:To describe the clinical presentation of failed SLAP repair due to knot-induced pain and evaluate the efficacy of arthroscopic knot removal.Study Design:Case series; Level of evidence, 4.Methods:The authors retrospectively reviewed records of 11 patients (mean age, 24.6 ± 8.6 years; range, 17-43 years) with stable, healed SLAP lesions with knot-induced pain after arthroscopic fixation of unstable type II SLAP lesions. All patients demonstrated a positive compression-rotation test before knot removal. The mean follow-up duration after knot removal was 48.0 ± 37.4 months (range, 24-156 months). The mean duration between primary fixation and knot removal was 21.2 ± 14.7 months (range, 8-56 months).Results:Sharp pain (100%) and clicking (64%) were the most ...
