Background: There are limited data comparing the outcomes of similarly matched patients with a medial meniscus posterior root tear (MMPRT) treated nonoperative management, partial meniscectomy, or repair. Purpose/Hypothesis: The purpose was to compare treatment failure, clinical outcome scores, and radiographic findings for cohort who underwent either transtibial pull-through repair an MMPRT. We hypothesized that will have lower rates progression arthroplasty than were management...

Background: The posterior cruciate ligament (PCL) is composed of 2 functional bundles and has an essential role in knee function stability. There is, however, a limited understanding the each individual bundle through full range flexion. Hypothesis: Both provide restraint to tibial translation across At higher angles flexion (>90°), intact PCL also imparts significant rotational Study Design: Controlled laboratory study. Methods: Twenty matched-paired, human cadaveric knees (mean age,...

Background: A more thorough understanding of the posterior cruciate ligament (PCL) has led to an increase in awareness and treatment complex PCL injuries. Controversy exists about whether reconstruction (PCLR) using anatomic single-bundle (aSB) or double-bundle (aDB) technique is most effective. Hypothesis: An aDB PCLR provides significantly better anterior-posterior rotatory knee stability compared with aSB closely recreates normal kinematics. Study Design: Controlled laboratory study....

Background: Prior studies have suggested that anatomic double-bundle (DB) posterior cruciate ligament reconstruction (PCLR) reduces residual laxity compared with the intact state better than single-bundle PCLR. Although anterolateral bundle (ALB) and posteromedial (PMB) reportedly act codominantly, few commonly used graft fixation angles influence on overall forces knee laxity. Hypothesis: Graft angle combinations of 0°/75° (PMB/ALB), 0°/90°, 0°/105°, 15°/75°, 15°/90°, 15°/105° would...

Background: When surgical intervention is required for a grade 3 superficial medial collateral ligament (sMCL) tear, there no consensus on the optimal treatment. Anatomic augmented repairs and anatomic reconstructions treatment of sMCL tears have not been biomechanically validated or compared. Hypothesis: reconstruction techniques will reproduce equivalent knee kinematics when compared with intact state, while creating significant improvements in translational rotational laxity sectioned...

Background: Currently, no consensus exists for the optimal graft fixation angle anatomic single-bundle (SB) posterior cruciate ligament reconstructions (PCLRs). Additionally, direct forces have not been measured. Alternative angles and resultant should be investigated to optimize stability of SB PCLRs without overconstraining knee. Hypothesis: Graft 75°, 90°, 105° PCLR were hypothesized improve knee compared with sectioned state evidence overconstraint. Study Design: Controlled laboratory...

Until recently, anterior cruciate ligament (ACL) tears in older patients were treated conservatively; however, these often experienced significant pain and instability.The purpose of this study was to compare the patient-reported outcomes, patient satisfaction, failure rates primary ACL reconstruction between a younger (age 20-30 years) 50-75 cohort. It hypothesized that cohort could achieve comparable clinical outcomes retear following with bone-tendon-bone autograft or allograft compared...

Anterior cruciate ligament reconstruction is one of the most commonly performed procedures in orthopaedics, with more than 125,000 United States per year. There are several graft choices that can be used to reconstruct native anterior ligament, autograft hamstring tendons being used. Preparation a varies depending on patient characteristics and physician preference. The purpose this Technical Note describe detail different variants preparation techniques practice.

Background: The effect of prior meniscectomy and the resulting reduction in meniscal tissue on a potential National Football League (NFL) player’s articular cartilage status performance remain poorly elucidated. Purpose/Hypothesis: (1) To determine epidemiology, imaging characteristics, associated pathology knee among players with previous who were participating NFL Combine (2) to evaluate these injuries as compared matched controls. hypothesis was that less would have worse inferior metrics...

Background: Meniscal repair is desirable over resection to prevent postmeniscectomy arthritis, especially among young and active patients. However, long-term data are currently lacking following isolated meniscal repair, particularly in the pediatric population. Purpose/Hypothesis: To report follow-up of tears treated by a adolescent population compare those results with previous midterm reported. The authors hypothesized that these patients would have satisfactory function reoperation rates...

Little is known about the benefits and outcomes of meniscal repair in patients older than 60 years.To (1) report clinical radiographic aged ≥60 years compare them with matched who underwent meniscectomy (2) identify procedural failures.Cohort study; Level evidence, 2.We included 32 knees (20 female, 12 male; mean age, 64.5 ± 4.6 years) surgery at a single medical institution between 2010 2020. Patients were according to sex, body mass index, tear type comparison cohort (n = 49 [49 knees]; 17...

Aims Contemporary outcomes of primary total hip arthroplasties (THAs) with highly cross-linked polyethylene (HXLPE) liners in patients inflammatory arthritis have not been well studied. This study examined the implant survivorship, complications, radiological results, and clinical THA arthritis. Methods We identified 418 hips (350 patients) a diagnosis who underwent HXLPE from January 2000 to December 2017. Of these hips, 68% had rheumatoid (n = 286), 13% ankylosing spondylitis 53), 7%...

Meniscal injuries and meniscal loss are associated with changes in knee kinematics loading, ultimately leading to poor functional outcomes increased risk of progression osteoarthritis. Biomechanical studies have shown restored function, clinical reported improved decreased osteoarthritis after repair. This has led orthopaedic surgeons try save the meniscus by repair whenever possible, as increasing incidence surgeries. Historically, lesions, particularly those greater size located...

Background: Studies have shown good and excellent clinical radiographic results after meniscal repair. Limited published information exists on the long-term outcomes, however, especially in a pediatric adolescent population. Purpose: To determine of repair concomitant anterior cruciate ligament (ACL) reconstruction Specifically, aims were to success rate with ACL reconstruction, compare midterm analyze risk factors for failure. Study Design: Case series; Level evidence, 4. Methods: Cases...

Injury to the anterior cruciate ligament (ACL) of knee is common and often requires surgical reconstruction. There are numerous graft options available operating surgeon, each which a growing body dedicated literature exists. Each these potential choices ACL specimen has distinctive set biomechanical properties, clinical outcome profiles, other special considerations (e.g., autograft versus allograft, harvest site factors, time). The purpose this review discuss characteristics native...
