Randomized Controlled Trial Comparative Study
Does Arthroscopic Suture-Spanning Augmentation of Single-Row Repair Reduce the Retear Rate of Massive Rotator Cuff Tear?
Several surgical techniques have been proposed for massive rotator cuff tears (MRCTs), but the failure rates remain high. The suture-spanning augmentation technique of single-row (SSA-SR) repair was shown to reduce failure rates in cadaveric studies, but the outcome in vivo remains unclear. ⋯ NCT03609164 (ClinicalTrials.gov identifier).

Arthroscopic Repair of the Isolated Subscapularis Full-Thickness Tear: Single- Versus Double-Row Suture-Bridge Technique.
No clinical comparative study has addressed isolated subscapularis tears after arthroscopic repair with either single-row or double-row suture-bridge technique. ⋯ Arthroscopic single-row repair and double-row suture-bridge repair of isolated full-thickness subscapularis tears both yielded satisfactory clinical outcomes and structural integrity with no significant differences among patients with good muscle quality.

Reconstruction of the medial patellofemoral ligament (MPFL) is widely acknowledged as an integral part of the current therapeutic armamentarium for recurrent patellar instability. The procedure is often performed with concomitant bony procedures, such as distalization of the tibial tuberosity or trochleoplasty in the case of patella alta or high-grade trochlear dysplasia, respectively. At the present time, few studies have evaluated the clinical effectiveness of MPFL reconstruction as an isolated intervention. ⋯ In cases of recurrent patellar instability, isolated MPFL reconstruction would appear to be a safe and efficient surgical procedure with a low failure rate. Preoperative failure risk factors identified in this study were patella alta with a CDI ≥1.3 and a preoperative positive J-sign.

Arthroscopic repair of delaminated rotator cuff tears (RCTs) has shown poor prognoses. Despite the importance of delaminated tears, only a few studies have compared delaminated and nondelaminated tears. ⋯ Delaminated RCT was a negative prognostic factor of structural integrity after repair and could affect the functional outcome. However, whether IST tear was involved had no effect on the prognosis after repair.

Do Outcomes or Subsequent Injuries Differ After Ulnar Collateral Ligament Reconstruction With Palmaris Versus Hamstring Autograft?
Ulnar collateral ligament reconstruction (UCLR) is a successful procedure in professional baseball players. It is unclear whether graft choice affects results. ⋯ Baseball players who underwent UCLR with hamstring autograft were more likely to sustain a subsequent lower extremity injury, whereas those who underwent UCLR with palmaris autograft had a trend toward sustaining more upper extremity injuries. No difference in performance or RTS rates existed between groups. Both groups significantly declined in WAR and WHIP after UCLR.
