PurposeThis study aimed to compare the clinical outcomes between single on‐lay and double on‐lay subpectoral biceps tenodesis (SPBT) using all‐suture type anchor in patients with concomitant long head of the biceps tendon (LHBT) lesions and rotator cuff tears.
MethodsThe study included 130 patients who underwent SPBT using all‐suture type anchor and arthroscopic rotator cuff repair. Single and double anchor on‐lay fixations were performed in 69 patients (group A) and 61 patients (group B), respectively. In 16 patients of group A and 36 patients of group B, a metallic wire was embedded at tenodesis site and difference of wire location pre‐and postoperatively was measured using simple radiography.
ResultsIn both groups, the mean visual analogue scale (VAS) score during motion, the mean UCLA and constant scores significantly improved at the last follow‐up (all p < 0.001). These scores were not significantly different between two groups. However, postoperatively, a significant difference was observed in the incidence of cosmetic deformity between two groups (p = 0.019). The cosmetic deformity was noted in 9 (13.0%) patients (Popeye deformity 7.2% and biceps softening 5.8%) in group A and 1 (1.6%) patient (Popeye deformity) in group B. In the subgroup analysis on biceps migration after the surgery, the mean migration distance of metal wire was 2.5 ± 3.0 mm in group A and 1.9 ± 2.6 mm in group B (n.s.). No patient had migration of > 10 mm.
ConclusionsSPBT using all‐suture type anchor was a favorable treatment option for lesions of the LHBT with rotator cuff tear. The clinical relevance of this study is the finding that double on‐lay fixation with all‐suture type anchor would result less cosmetic deformity than the single on‐lay fixation for those who need subpectoral biceps tenodesis.
