Purpose: To prospectively compare the healing rates and functional outcomes of large and massive rotator cuff tears repaired with either a load-sharing rip-stop (LSRS) technique or single-row (SR) repair.
Methods: We performed a retrospective comparison of arthroscopic rotator cuff repairs of large and massive tears performed with 2 different repair techniques. Over a 1-year period, all tears with limited tendon mobility were repaired with an LSRS technique. Over the following 1-year period, all similar tears were repaired with an SR technique. There were 17 patients in the LSRS repair group and 18 in the SR repair group. Healing was assessed with ultrasound at a minimum of 6 months postoperatively, and functional outcome was assessed at a minimum of 24 months.
Results: No difference in postoperative range of motion was found between the 2 groups. Likewise, no difference in the visual analog scale score for pain or functional outcomes according to the American Shoulder and Elbow Surgeons, Simple Shoulder Test, or Single Assessment Numeric Evaluation score was found between the 2 groups. Complete rotator cuff healing was observed in 53% of LSRS repairs compared with 11% of SR repairs (P = .010).
Conclusions: At short-term follow-up, there is no difference in functional outcomes after an LSRS technique versus an SR repair technique for large and massive rotator cuff tears with limited tendon mobility. However, structural healing appears to be higher with an LSRS technique.
Level Of Evidence: Level III, retrospective comparative study.

Rotator cuff tears in the shoulder joint are common musculoskeletal injuries that may present with or without symptoms. Rotator cuff tears are a common musculoskeletal condition that become increasingly prevalent with age. This mines various surgical interventions for rotator cuff tears, focusing on patient selection criteria and treatment outcomes across different subgroups.

Objective: To evaluate the prevalence of shoulder pain, level of functional performance, and morphological involvement of the rotator cuff on ultrasound in morbidly obese patients.
Methods: The study included 54 morbidly obese patients receiving follow-up care in a bariatric surgery outpatient clinic, which were compared with a control group consisting of 49 participants. Presence of shoulder pain, shoulder functional performance, ultrasound of the rotator cuff and blood tests were the parameters evaluated.
Is calcification integral to enthesopathy and tendinopathy rather than a separate disease process?

Background: The pathophysiology of enthesopathy and tendinopathy is mucoid degeneration, which includes chondroid metaplasia. The chondroid metaplasia can be associated with calcification. Inflammation is typically absent unless calcification triggers a self-limited immune response representing acute calcific tendinitis.

Introduction: Calcific tendonitis is characterized by calcium hydroxyapatite crystal deposition in tendons, leading to inflammation and pain. While predominantly observed in the rotator cuff tendons of the shoulder, its occurrence in the rectus femoris tendon of the hip is exceedingly rare and poses a diagnostic challenge.
Case Report: A 38-year-old female housewife presented with a 1-month history of left hip pain, which was dull, aching, and exacerbated by movements such as standing and walking.

Rotator cuff injury (RCI), characterized by shoulder pain and restricted mobility, represents a subset of tendon-bone insertion injuries (TBI). In the majority of cases, surgical reconstruction of the affected tendons or ligaments is required to address the damage. However, numerous clinical failures have underscored the suboptimal outcomes associated with such procedures.
