Background: Arthroscopic biceps tenodesis (ABT) high in the groove can be achieved using an inlay or an onlay technique. However, there is little information comparing outcomes between the 2. Purpose: To compare postoperative healing and functional outcomes of ABT high in the groove performed using either an onlay or an inlay technique. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective study was performed on patients undergoing ABT at the articular margin (high in the groove) at a single center over a 2-year period. An inlay technique using an interference screw was performed during the first year, followed by an onlay technique using a knotless suture anchor during the second. Tendon healing, elbow flexion strength, functional outcome, and complications were evaluated at a postoperative minimum of 1 year. Results: A total of 37 patients with inlay and 53 with onlay ABTs were available for follow-up. There was no difference in range of motion, functional outcome scores, or elbow flexion strength between the groups. A postoperative popeye deformity was noted in 27% of patients in the inlay group as compared with 9.4% of the onlay group (P= .028). Four patients (10.8%) in the inlay group required revision surgery (2 of which were biceps tenodesis related) as compared with 0% in the onlay group (P= .015). Conclusion: An onlay technique using a knotless suture anchor for ABT at the top of the articular margin is an acceptable alternative to an inlay technique using an interference screw. The onlay technique was associated with lower rates of postoperative popeye deformity and revision surgery as compared with the inlay technique.
