Abstract

Background: The long head of the biceps tendon (LHBT) is a well-known source of pain in the shoulder, especially in active patients.

Purpose: To evaluate the outcomes and return-to-sports rate after all-arthroscopic suprapectoral tenodesis of the LHBT using a small knotless anchor.

Study design: Case series; Level of evidence, 4.

Methods: In this retrospective study, 27 patients-who underwent all-arthroscopic tenodesis of the LHBT using a 2.7-mm knotless polyether ether ketone anchor-were evaluated. Sports activities, the return-to-sports rate, and other sports-related parameters (eg, pain during sports, level of sports) were examined. Sports-related data, the Constant score with isometric force (at 90° of abduction in the scapular plane), the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST) score, the visual analog scale (VAS) score for satisfaction, range of motion, and the presence of a Popeye deformity were assessed at a mean follow-up of 15.3 ± 8.7 months. The data were initially analyzed using descriptive statistics.

Results: The postoperative ASES, Constant, and SST scores were 81.61, 85.74 and 8.85, respectively. Of the 27 patients, 4 patients (14.8%) showed a Popeye deformity. Preoperatively, 25 patients (92.6%) participated regularly in some type of sports activity. All 25 patients (100.0%) were able to return to sports activities after surgery. 24 (96.0%) returned to the same level preoperatively, with 88.0% (22/25) within 6 months. Patient satisfaction with the outcome was high (VAS score: 2.15 ± 2.78). Neither bicipital groove pain nor cramping was reported. There were no signs of osteolytic bone around the anchor or a fracture of the humeral bone.

Conclusion: Our clinical results after using a 2.7-mm knotless anchor for LHBT tenodesis as well as the return-to-sports rate were satisfying. Using an anchor this size can lower the risk of cortical bone damage and therefore the risk of fractures of the humeral head while still enabling patients to perform at a high level.
