One-Year Follow-Up Is Sufficient Time for Patient-Reported Outcomes Following Rotator Cuff Repair: A Systematic Review and Meta-analysis.

Purpose: To perform a systematic review to determine whether there were clinically significant differences in patient-reported outcome measures from 1- to 2-year follow-up following rotator cuff repair (RCR).

Methods: A literature search of 3 databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) reporting on patient-reported outcomes at the 1- and 2-year follow-up following RCR were included.

Mechanisms and Trends in Women's Lacrosse Head and Musculoskeletal Injuries: A 15-Year Review of National Injury Data.

Background: Head injury rates in lacrosse may be higher among women compared with men. Understanding these trends can guide appropriate injury prevention for female athletes.

Hypotheses: Injuries most commonly involve the head, with no significant decline over the study period; contact with other players would be the most common injury mechanism.

Acetabular Screws With Cement Augment for Tibial Plateau Defects in Dynamic Spacer Implantation: A Case of Recalcitrant Native Knee Septic Arthritis.

Treating tibial bone defects in the setting of recalcitrant native knee arthritis presents a challenging biomechanical problem for orthopaedic surgeons. A dynamic antibiotic spacer offers an effective solution to preserve patient function and manage infection. However, severe bone loss may compromise the fixation of the dynamic spacer.

Patients With First-Time or Recurrent Patellar Dislocation Have a Similar High Rate and Extent of Articular Cartilage Injury Observed on Magnetic Resonance Imaging.

Purpose: To use magnetic resonance imaging (MRI) scans to compare the prevalence of articular cartilage damage in patients with a single patellar dislocation versus those with multiple dislocations and to compare the locations and severity of chondral injury between the groups.

Methods: Patients with patellar dislocation between January 2017 and July 2021 were retrospectively identified. Patients with a documented history of patellar dislocation and an MRI scan of the affected knee were included.

Rat Microvascular Model is Tolerant to Technical Errors.

Background:  Extensive studies have been conducted using the rat model to understand the potential technical errors that lead to anastomotic failure. However, current literature indicates that the rat model has excellent tolerance to diverse errors committed by microsurgeons. The error-investigating rat model is often created by one or two experienced surgeons, and only one isolated technical error is examined.

Outcomes and Complications Following Chronic Patellar Tendon Repair: A Systematic Review.

The purpose of this systematic review is to report outcomes and complications following the reconstruction of chronic patellar tendon ruptures. Four databases (Cochrane Database of Systematic Reviews, PubMed, Embase, MEDLINE) were searched from inception to July 2021. Inclusion criteria included articles that (1) analyzed outcomes and complications following chronic patellar tendon reconstruction (>4 weeks from injury to repair), (2) were written in English, (3) greater than five patients, and (4) a minimum 2-year follow-up.

Swan Neck Deformity: An Unusual Complication Following Trigger Finger Release.

Introduction: Swan neck deformity (SND) is a common pathologic finding often observed in patients with severe rheumatoid arthritis. However, it has also been seen in injuries such as mallet finger, flexor digitorum superficialis laceration, and intrinsic contracture. Open surgical release of a trigger finger most commonly involves the release of the A1 pulley to relieve a mechanical impingement.

Resorbable Nerve Wraps: Can They Be Overtightened?

Background:  Nerve wrapping has been advocated to minimize scarring and adhesion following neurorrhaphy or neurolysis. A wrap should provide an enclosure that is snug enough to protect and support the affected nerve without strangulating the nerve. The degree to which resorbable wraps should be ": tightened" around the nerve is largely subjective with scant literature on the subject.

Smoothing the steep microsurgery learning curve: considering alternative suture sizes for early-stage microsurgery training with in vivo rat models.

Background: Laboratory microsurgery training using invivo rat models is essential for clinical operation. However, challenges existin a structured training course when students transition from a non-livingmodel exercise to a living one. In the present article, we first demonstratethis steep learning curve in early-stage microsurgery training.

The Utility of Continuous Passive Motion After Anterior Cruciate Ligament Reconstruction: A Systematic Review of Comparative Studies.

Background: The application of continuous passive motion (CPM) after anterior cruciate ligament reconstruction (ACLR) was popularized in the 1990s, but advancements in the understanding of ACLR rehabilitation have made the application of CPM controversial. Many sports medicine fellowship-trained surgeons report using CPM machines postoperatively.

Purpose: To determine the efficacy of CPM use for recovery after ACLR with respect to knee range of motion (ROM), knee swelling, postoperative pain, and postoperative complications.

Octogenarians Undergoing Medial Unicompartmental Knee Arthroplasty Have Similar Patient-Reported Outcomes as Their Younger Counterparts.

Background: As a procedure with lower surgical morbidity, unicompartmental knee arthroplasty (UKA) may present a practical solution for elderly patients with unicompartmental arthritis. However, few studies have analyzed the results of UKA in the extreme elderly. This study compared the functional and perioperative outcomes between octogenarians and age-appropriate controls undergoing UKA.

Large and Uneven Bites in End-to-End Anastomosis of the Rat Femoral Artery.

Background:  Successful microvascular anastomosis depends on sutures that adequately oppose both cut vessel edges. Trainees tend to take oversized or uneven bite. To improve early microsurgical skill acquisition using the rat, this study tests the belief that such bites compromise early patency by applying exaggerated bites to end-to-end arterial anastomoses.

Torsion is Tolerated in Arterial End to Venous Side Anastomoses in the Rat Model.

Background:  End-to-side (ETS) anastomoses are necessary for many procedures in microvascular surgery, such as free flap transfers. In training courses that use the rat model, the arterial end to venous side (AEVS) anastomosis is a common training exercise for ETS anastomoses. Surgeons-in-training often inadvertently twist the artery when completing the AEVS anastomosis; however, in the clinical setting, torsion is a reported risk factor for ETS anastomosis failure.

Creation of a Rat Lower Limb Lymphedema Model.

Background: Lymphedema is a frequent complication after surgical treatments of cancer involving lymph node resection. However, research of lymphedema treatments, such as vascularized lymph node transfer, is limited by the absence of an adequate lymphedema animal model. The purpose of this study was to determine if we could create sustainable lower limb lymphedema in the rat with a combination of inguinal lymphadenectomy, circumferential skin and subcutaneous tissue excision, and radiotherapy.
