Purpose: To evaluate the cost-effectiveness of nonoperative management, primary SLAP repair, and primary biceps tenodesis for the treatment of symptomatic isolated type II SLAP tear.

Methods: A microsimulation Markov model was constructed to compare 3 strategies for middle-aged patients with symptomatic type II SLAP tears: SLAP repair, biceps tenodesis, or nonoperative management. A failed 6-month trial of nonoperative treatment was assumed. The principal outcome measure was the incremental cost-effectiveness ratio in 2017 U.S. dollars using a societal perspective over a 10-year time horizon. Treatment effectiveness was expressed in quality-adjusted life-years (QALY). Model results were compared with estimates from the published literature and were subjected to sensitivity analyses to evaluate robustness.

Results: Primary biceps tenodesis compared with SLAP repair conferred an increased effectiveness of 0.06 QALY with cost savings of $1,766. Compared with nonoperative treatment, both biceps tenodesis and SLAP repair were cost-effective (incremental cost-effectiveness ratio values of $3,344/QALY gained and $4,289/QALY gained, respectively). Sensitivity analysis showed that biceps tenodesis was the preferred strategy in most simulations (52%); however, for SLAP repair to become cost-effective over biceps tenodesis, its probability of failure would have to be lower than 2.7% or the cost of biceps tenodesis would have to be higher than $14,644.

Conclusions: When compared with primary SLAP repair and nonoperative treatment, primary biceps tenodesis is the most cost-effective treatment strategy for type II SLAP tears in middle-aged patients. Primary biceps tenodesis offers increased effectiveness when compared with both primary SLAP repair and nonoperative treatment and lower costs than primary SLAP repair.

Level Of Evidence: Level III, economic decision analysis.

Article Synopsis
  • - The study aimed to evaluate the fixation strength and performance of three different devices used for securing the proximal biceps to the humerus in sheep, using a total of 27 tests across three groups: metallic anchors, biocomposite knotless devices, and metallic interference screws.
  • - The results indicated no significant difference in fixation strength or tendon displacement among the three techniques, although each device had distinct failure patterns: metallic anchors ruptured at the myotendinous junction, knotless anchors failed at the wire-screw interface, and interference screws slipped at the tendon.
  • - Overall, all three fixation methods demonstrated substantial resistance to tensile loads, suggesting equivalency in performance; further studies on cyclic load resistance could enhance comparisons between these

Background: The superior labrum and biceps complex is commonly implicated in shoulder pain and there remains discordance regarding the surgical management of superior labrum anterior to posterior (SLAP) tears. The purpose of this study was to establish an expert consensus regarding the management of superior labrum and biceps complex pathology.

Methods: The NEER Circle is an organization of shoulder experts recognized for their service to the American Shoulder and Elbow Surgeons (ASES) society.

Purpose: To compare clinical and radiologic outcomes between biceps anchor tenodesis (AT), biceps soft-tissue tenodesis (ST), and biceps tenotomy (TT) for patients with concomitant rotator cuff repair (RCR).

Methods: This retrospective study reviewed patients who underwent arthroscopic RCR for full-thickness rotator cuff tears with AT, ST, or TT with minimum 2-year follow-up. All biceps procedures were performed arthroscopically, and ST consisted of fixation to the transverse humeral ligament.

Introduction While several studies have compared tenotomy and tenodesis, few studies have examined whether performing a tenodesis of the long head of the biceps (LHB), when indicated, in patients who have undergone rotator cuff reconstruction has a detrimental impact on clinical and radiological postoperative outcomes. The present study aimed to investigate whether performing a tenodesis of the LHB has a damaging effect on the clinical and radiological outcome after rotator cuff reconstruction. Material and methods Fifty-one patients surgically treated for supraspinatus (SSP) tendon tears were included.
