Studies on adherence to neuromuscular training (NMT) for anterior cruciate ligament (ACL) injury prevention are frequently biased due to the use of self-reporting by coaches or the athletes themselves. Few NMT studies use data collectors (aside from the athletes or the individuals administering the NMT program) to decrease bias when assessing adherence of coaches and sports teams. We hypothesized that

Endoscopic anterior capsulectomy for severe elbow contractures J. ISAKOS Pub Date : 2024-02-17 Deepak N. Bhatia
Elbow stiffness secondary to trauma or surgical reconstruction can sometimes result in a severe contracture with restricted joint space, and arthroscopic access to the joint is difficult. Previous surgery and severe stiffness can also alter the position of neurovascular structures and iatrogenic injury is possible with an inside-out arthroscopic approach. To overcome these technical difficulties, an

ISAKOS Pub Date : 2023-12-21 Riccardo D’Ambrosi, Fabrizio Di Maria, Chiara Ursino, Nicola Ursino, Fabrizio Di Feo, Matteo Formica, Srinivas BS. Kambhampati
Importance The diagnosis of ramp lesions can be problematic, even with arthroscopy, due to their extreme posteromedial position. Consequently, they have been colloquially referred to as the "hidden lesions" of the knee. Undiagnosed and untreated injuries in this knee region may be associated with ongoing dynamic rotational laxity of the knee after anterior cruciate ligament reconstruction and an increased

Lesniak, Dharmesh Vyas
Objective The purpose is to compare functional outcomes, return to soccer rates, and revision rates in an all-female soccer player cohort undergoing quadriceps tendon (QT) autograft ACLR versus bone-patellar tendon-bone (BPTB) autograft ACLR. Methods Female soccer players who sustained an ACL rupture and underwent primary anatomic, single-bundle ACLR with BPTB autograft or QT autograft were included

Different Types of Rotator Cuff Tear Morphology Do Not Affect Post-Repair Clinical Outcomes in Large to Massive Tears J. ISAKOS Pub Date : 2023-11-03 Mark HX. Yeo, Shawn JS. Seah, Merrill Lee, Denny Lie
Objectives The primary aim of this current study is to evaluate the effects of rotator cuff tear morphology (RCTM) on clinical outcomes in large to massive tears, using a modified version of the existing classification system, with specific focus on tear symmetry and use of margin convergence. Methods Patients who underwent arthroscopic repair of large to massive, full thickness rotator cuff tears

Classification Of Elbow Stiffness J. ISAKOS Pub Date : 2023-11-02 Alessandro Marinelli, Enrico Guerra, Gregory Bain
Stiffness is a clinical disorder that affects the patient’s function of the entire upper limb. Many classifications systems have been developed for elbow stiffness based on the plane of motion, severity, etiology, prognosis or anatomical location. A new classification, the Stiffness types and Influencing Factors (S.T.I.F.) Classification System, is proposed as treatment algorithm to guide the surgical

Controversies in Surgical Management of Anterior Shoulder Instability. State of the Art J. ISAKOS Pub Date : 2023-10-29 Raffy Mirzayan, Eiji Itoi, Jillian Karpyshyn, Ivan H. Wong, Giovanni Di Giacomo
Arthroscopic Bankart repair has been accepted as a standard procedure for anterior shoulder instability with a minimum or no glenoid bone loss and an on-track Hill-Sachs lesion if present. However, several controversies exist in the surgical treatment of anterior shoulder instability. This article will discuss some of these controversies in “simple” dislocations (without bone loss) as well as “complex”
