Clinical and Radiological Outcomes After Lateral Meniscal Allograft Transplantation Through a Medial Arthrotomy: A Minimum 4-Year Follow-up.

Background: Previous studies have demonstrated that lateral meniscal allograft transplantation (MAT) through medial arthrotomy showed less extrusion than that of the lateral arthrotomy. However, there is a paucity of literature reporting clinical and radiological outcomes after lateral MAT through the medial arthrotomy.

Hypothesis: Lateral MAT through a medial arthrotomy would show significantly improved clinical scores and minimal joint space narrowing compared with preoperative status.

Tibial-sided Anterolateral Ligament Injuries Are Associated With Poor Healing and Residual Pivot Shift Testing After Anterior Cruciate Ligament Reconstruction.

Purpose: To investigate whether tibial-sided anterolateral ligament (ALL) injuries are associated with poor healing and residual pivot shift.

Methods: Patients who underwent anterior cruciate ligament reconstructions within postinjury 6 weeks from January 2008 to March 2021 were included. They had concomitant ALL injury confirmed by preoperative magnetic resonance imaging (MRI) and were followed for a minimum of 20 months.

Increase in Deltoid Compartment Pressures Immediately After Arthroscopic Rotator Cuff Repair Does Not Significantly Affect Postoperative Opioid Consumption.

Purpose: To investigate the association between changes in individual (anterior, lateral, and posterior) and overall deltoid compartment pressures and postoperative opioid consumption up to 14 days after primary double-row arthroscopic rotator cuff repair (ARCR).

Methods: In 113 consecutive patients undergoing primary double-row ARCR, anterior, lateral, and posterior deltoid compartment pressures were measured prior to incision and immediately after closure with a manometer. Postoperatively, all patients were provided with an identical rehabilitation protocol, quantity and dose of opioid tablets, and pain journal in which to record daily opioid consumption and visual analog scale pain scores for 14 days after surgery.

Patients who have undergone total shoulder arthroplasty prefer greater surgeon involvement in shared decision making.

Background: There has been a shift in medical decision making from a paternalist model to a shared decision-making (SDM) approach, described as a patient-physician relationship where both parties collaborate to arrive on an evidence-based treatment regimen that best suits the patient's needs and values. However, there is a scarcity in evidence regarding SDM in shoulder arthroplasty. The purpose of this study was to evaluate overall patient preference for SDM and determine demographic and socioeconomic factors related to SDM preference in those undergoing shoulder arthroplasty.

Correlation Between Anatomic Landmarks and Bony Trough Position in Lateral Meniscal Allograft Transplant.

Background: Determining the rotational axis of the bony trough during lateral meniscal allograft transplant (MAT) is difficult. The use of anatomic landmarks may help a surgeon determine the rotational alignment of the graft during the procedure.

Purpose: To investigate the association between the knee's anatomic landmarks and the position of the bony trough to prevent extrusion after lateral MAT.

Accuracy of the Arthroscopic Location of the Center of the Anterior Horn During Lateral Meniscal Allograft Transplantation.

Background: Anatomic placement of the meniscal allograft is imperative to achieve satisfactory outcomes after meniscal allograft transplantation (MAT). Few studies have reported on the accuracy of the provisional location of the center of the anterior horn of the lateral meniscus (AHLM).

Hypothesis: The authors hypothesized that the provisional center would not coincide with the anatomic center of the AHLM.

Lateral Capsular Stabilization in Lateral Meniscal Allograft Transplantation.

Background: Stabilization of the lateral capsule to the tibial plateau may decrease midbody extrusion after lateral meniscal allograft transplantation (MAT).

Methods: Inclusion criteria were female patients (ACL group, n = 59) undergoing primary ACL reconstruction from 2012 to 2018. Control female patients (control group, n = 58) were matched by age, height, and body mass index to ACL group.

Comparison Between Early and Late Retensioning of an Adjustable-Loop Cortical Suspension Device During Hamstring ACL Reconstruction.

Background: Biomechanical studies have demonstrated significant loosening of the adjustable-loop device as compared with the fixed-loop device used in anterior cruciate ligament reconstruction. Retensioning of the adjustable loop has been recommended; however, the timing of the retensioning is unknown.

Hypothesis: Early (ER) and late retensioning (LR) will show similar gapping between the femoral tunnel and graft on follow-up magnetic resonance imaging (MRI) and similar clinical outcomes.

Oral Ketorolac as an Adjuvant Agent for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair: A Prospective, Randomized, Controlled Study.

Background: Arthroscopic rotator cuff repair (RCR) is associated with substantial postoperative pain. Oral narcotic agents are the preferred analgesic postoperatively. However, these agents are associated with several side effects and a potential for abuse.

The purpose of this study is to determine whether the hamstring grafts are fully inserted into the femoral tunnel with the adjustable loop using immediate postoperative magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) reconstructions. A total of 62 consecutive patients underwent hamstring ACL reconstruction using an adjustable-loop cortical suspension device for the femoral fixation and the Intrafix sheath and screw for the tibial fixation. Multiplanar reformatted images of 3-T MRI scans were obtained at the 1st postoperative day before weight bearing is initiated in all patients to evaluate the gap (the tunnel-graft gap) between the top of the hamstring graft and top of the femoral tunnel.

Lateral Meniscal Allograft Transplant via a Medial Approach Leads to Less Extrusion.

Background: Accurate positioning of the bony bridge is crucial to prevent extrusion of meniscal allografts after transplant. However, oblique or lateralized placement of the bony bridge of the lateral meniscal allograft may occur due to technical error or a limited visual field. The patellar tendon may be an obstacle to approaching the anterior horn of the lateral meniscus, resulting in a laterally placed allograft.

Clinical and Radiological Outcomes After Hamstring Anterior Cruciate Ligament Reconstructions: Comparison Between Fixed-Loop and Adjustable-Loop Cortical Suspension Devices.

Background: Few studies have compared clinical and radiological outcomes after hamstring anterior cruciate ligament (ACL) reconstruction with fixed-loop and adjustable-loop cortical suspension devices. Purpose/Hypothesis: The purpose of this retrospective study was to compare clinical outcomes and tunnel widening after hamstring ACL reconstructions with fixed- and adjustable-loop cortical suspension devices. The hypothesis was that compared with femoral graft fixation with the fixed-loop device, fixation with the adjustable-loop device would show similar clinical outcomes and would result in less tunnel widening after hamstring ACL reconstruction.

Cost Analysis of Hemiarthroplasty Versus Reverse Shoulder Arthroplasty for Fractures.

Complex proximal humerus fractures in older patients can be treated with hemiarthroplasty (HA) or reverse shoulder arthroplasty (RSA), with both providing good pain relief and function. This study compared the costs, complications, and outcomes of HA vs RSA after proximal humerus fracture in older patients. Patients 65 years or older who were admitted between January 2007 and August 2011 with a 3- or 4-part proximal humerus fracture and treated with HA or RSA were identified.
