TL;DR: The overall prevalence of a ramp lesion in patients treated for ACL ruptures at the authors' institution was 42%, and the presence of bone marrow edema of the posteromedial tibia, a contact injury mechanism, or a lateral meniscal tear should alert surgeons to the potential presence of a medial meniscal ramp lesions.
Abstract: Background:Ramp lesions are peripheral tears of the posterior horn of the medial meniscus that involve the meniscocapsular attachments or red-red zone and typically occur in conjunction with anteri...
TL;DR: Increased posterior tibial slope, as measured from lateral knee radiographs, was associated with increased risk of graft rupture and contralateral ACL injury after revision ACL reconstruction, consistent with the concept that increased posterior slope, particularly of the lateral tibIAL plateau, is an important risk factor for recurrent ACL injury.
Abstract: Background:Increased posterior tibial slope has been identified as a possible risk factor for injury to the anterior cruciate ligament (ACL) and has also been shown to be associated with ACL recons...
TL;DR: Placement of the subacromial balloon spacer is a minimally invasive, technically simple procedure with favorable patient-reported outcomes at limited short-term follow-up, however, inherent methodological limitations and patient heterogeneity between studies may impair the ability to fully characterize the longer term efficacy.
Abstract: Background:Selection of optimal treatment for massive to irreparable rotator cuff tears (RCTs) entails a challenging decision-making process in which surgeons must consider several factors, includi...
TL;DR: MRI evaluation of the anterolateral ligament (ALL) was associated with good and very good inter- and intraobserver reliabilities, and it demonstrated abnormalities of the ALL in the majority of acutely ACL-injured knees.

TL;DR: Inside-out meniscal repair is recommended for potentially reparable meniscal tears in all 3 vascular zones; however, improved outcomes can be achieved when performed acutely, in the absence of full-thickness femoral condyle chondral injuries, and in the red-red and red-white zones.
Abstract: Background:There is significant discrepancy in the reported vascularity within the meniscus, and a progressively diminishing blood supply may indicate a differential healing capacity of tears that ...
TL;DR: While there were no physeal complications in either group, patients undergoing ACL reconstruction with a hamstring tendon autograft were more likely to tear their graft than the quadriceps tendon grafts, which were associated with a lower retear rate.
Abstract: Background:It is unclear what the optimal graft choice is for performing anterior cruciate ligament (ACL) reconstruction in a skeletally immature patient.Purpose:To evaluate outcomes and complicati...

Abstract: Background:Given the proximity of the medial patellofemoral ligament (MPFL) femoral insertion to the distal femoral physis in skeletally immature patients, multiple techniques for femoral graft fix...
TL;DR: NBA players presenting with symptomatic foot and ankle injuries had a fairly “normal” foot morphology, with a tendency toward a varus hindfoot and a high-arched morphotype, and weightbearing cone beam computed tomography may help to shed light on anatomic risk factors for common injuries in professional players and may aid in the planning of specific prevention programs.

Abstract: Background:Quadriceps tendon (QT) autografts are being increasingly used for anterior cruciate ligament reconstruction (ACLR). A paucity of studies exist that compare QT autografts with alternative...
TL;DR: In a majority of lesions, MRI overestimated OLT area and diameter compared with arthroscopy, and surgeons should be aware of the discrepancies that can exist between MRI and ar Throscopic measurements, as these data are important in making treatment decisions and educating patients.
Abstract: Background:Lesion size is a major determinant of treatment strategy for osteochondral lesions of the talus (OLTs). Although magnetic resonance imaging (MRI) is commonly used in the preoperative eva...
TL;DR: Primary arthroscopic hip labral reconstruction yielded improvements in patient-reported outcome scores and high patient satisfaction, and hamstring allografteds and autografts may be considered comparable graft choices for primary reconstruction.
Abstract: Background:Labral reconstruction has been described as a solution for the irreparable labrum. Initial techniques employed autografts, while more recent procedures have utilized allografts. No study...
TL;DR: Good clinical outcomes after BMS at midterm follow-up for primary OLTs were found and radiological outcomes showed repair tissue surface damage in the majority of patients, which may be a harbinger for long-term problems.
Abstract: Background:Bone marrow stimulation (BMS) is a common surgical intervention in the treatment of small osteochondral lesions of the talus (OLTs). Evidence has shown good clinical outcomes after BMS i...
