Level IV, therapeutic case series.

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.

For patients with concomitant type II SLAP lesions and large to massive rotator cuff tears, the outcomes of simultaneous arthroscopic SLAP and rotator cuff repair were inferior to those of arthroscopic biceps tenotomy and cuff repair in terms of functional shoulder scores and range of motion. Biceps tenotomy and rotator cuff repair may be a more reliable method to address concomitant type II SLAP lesions and large to massive rotator cuff tears in patients, although a randomized controlled trial

After arthroscopic repair of anterosuperior massive RCTs, 53% of patients exhibited retearing. The healed group had better functional outcomes than the retear group. The subscapularis retear subgroup exhibited significantly inferior outcomes compared with the intact subscapularis repair subgroup.

The all-layers repair did not produce better clinical outcomes or structural integrity than the bursal layer-only repair. The study findings indicate that if repair of the articular layer is possible only under significant tension or is not reparable, rather than all-layers repair by force, bursal-layer repair without incorporating the articular layer may produce comparable clinical outcomes and structural integrity in the delaminated rotator cuff tear.

The objectives of this study are to evaluate the contributions of the popliteofibular ligament (PFL), the popliteus tendon (PT), and the lateral (fibular) collateral ligament (LCL) to the posterolateral stability of the knee by changing the sequence of selective transection. Twelve fresh-frozen cadaveric knees were divided into two groups. Group 1 has a cutting sequence as follows: PFL, PT, LCL. Group 2 has a cutting sequence as follows: PT, PFL, LCL. Each specimen was mounted on the apparatuses

Both articular and bursal side PTRCTs showed significant functional improvements after arthroscopic repair. The bursal side tears had a higher incidence of impingement sign at preoperative examination and more often had a protruded spur on the acromion undersurface.

Even though we found a statistically significant difference between the 2 repair methods, it is still unknown if this statistical difference seen in our study has any clinical and radiologic significance.

Among revision rotator cuff repairs, 43.1% had neglected subscapularis tears, and fatty infiltration of these initially neglected subscapularis tendons showed further progression at the time of revision. The retear rate after the repair of neglected subscapularis tears was higher than expected. Thus, detecting and treating subscapularis tear via meticulous preoperative evaluation and thorough inspection during primary arthroscopy are essential.

Isolated repair of the subscapularis tendon in irreparable massive rotator cuff tears involving the subscapularis tendon yielded satisfactory short-term outcomes and structural integrity in patients in their 50s and 60s without arthritis. If patients with irreparable massive rotator cuff tears involving the subscapularis tendon are relatively young or have minimal concomitant arthritis, this repair can be worthwhile.
