Background: There is growing evidence that medial meniscotibial ligament (MTL) deficiency and meniscus extrusion may precede the development of some posterior root (MMPR) tears. However, no study has investigated biomechanical consequences MTL on MMPR. Hypothesis: (1) leads to increased extrusion, (2) correlated with compression shear forces at MMPR, (3) repair restores MMPR native levels. Study Design: Controlled laboratory study. Methods: Fifteen pairs fresh-frozen cadaveric knees were...
Traditional freehand techniques in high tibial osteotomy (HTO) have been shown to lack precision and accuracy. Patient-specific instrumentation (PSI) fixation created from cross-sectional imaging recently introduced address this problem. The purpose of the study was compare traditional versus PSI a human cadaveric model HTO. It hypothesized that osteotomies performed using would require less radiation exposure for operating room staff reduce deviation planned correction coronal, sagittal,...
Meniscal extrusion often persists after a medial meniscus root repair. If the is extruded, function of as load-sharing device and secondary knee stabilizer compromised.It was hypothesized that repairing meniscotibial ligament (MTL) would decrease meniscal in settings both an isolated MTL tear repaired while also improving compartment contact mechanics.Controlled laboratory study.Ten fresh-frozen cadaveric knees (mean age, 50.5 years) were tested 5 conditions: intact, deficiency, deficiency +...
Knowledge of anatomy and physiology the meniscus is essential for appropriate treatment. The unique medial lateral blood supply play an important role in decision making. Controversy exists regarding optimal treatment meniscal tears including débridement, repair, root transplantation. tear location morphology thus plays determination Repair generally advised types with healing potential to preserve function joint health.
Background: Meniscal and chondral damage is common in the patient undergoing revision anterior cruciate ligament (ACL) reconstruction. Purpose: To determine if meniscal and/or articular cartilage pathology at time of ACL surgery significantly influences a patient’s outcome 6-year follow-up. Study Design: Cohort study; Level evidence, 3. Methods: Patients reconstruction were prospectively enrolled between 2006 2011. Data collection included baseline demographics, surgical technique,...
Abstract The purpose of this study is to determine whether any regional or age-related patterns exist in graft choice for patients undergoing primary anterior cruciate ligament reconstruction (ACLR) within a large multicenter consortium. A retrospective cohort was performed using data collected from the Multicenter Orthopaedic Outcomes Network (MOON) on having undergone ACLR. Patients were stratified by age group (younger than 20, 20–29, 30–39, 40–49, and 50+ years) four demographic regions...
Multiple meniscal repair techniques exist, and successful healing excellent patient outcomes have been reported with a variety of all-inside open techniques. Increased awareness recognition root tears meniscocapsular separations are topics recent interest. The ideal treatment these injuries remains uncertain, definitive recommendations regarding their lacking. Postoperative protocols weight bearing range motion controversial require future study. role biologics in the augmentation unclear...
The posterior medial meniscal root (PMMR) experiences variable and multiaxial forces during loading. Current methods to measure these are limited fail adequately characterize the loads in all three dimensions at root. Our novel technique resolved limitations with installation of a 3-axis sensing construct that we hypothesized would not affect contact mechanics, impart extraneous onto PMMR, accurately forces, deflect under joint loads. Six cadaveric specimens were dissected capsule...
Autologous chondrocyte implantation (ACI) and matrix-induced autologous (MACI) are performed to treat focal chondral defects (FCDs); both 2-step procedures involving a biopsy, followed by transplantation. There is little published research evaluating ACI/MACI in patients who undergo biopsy alone.To determine (1) the value of cartilage biopsies concomitant with FCDs knee (2) conversion rate transplantation as well reoperation.Case series; Level evidence, 4.A retrospective review was 46 (63%...
Posterior medial meniscus root (PMMR) tears are a challenge to assess and treat. However, the forces sustained at PMMR yet be fully characterized. In addition, it has been shown that meniscotibial ligament (MTL) injuries happen before tears, suggesting insufficiency of MTL results in change acting on PMMR.The purpose this study was evaluate 3-dimensional intact, cut, tenodesis states. It hypothesized cut state would increase shear seen PMMR, whereas force return intact state.Controlled...
The Multicenter Orthopaedic Outcomes Network Shoulder Group conducted a prospective cohort study of 452 patients with symptomatic atraumatic rotator cuff tears treated physical therapy program to determine the predictors failure nonsurgical treatment, provide insight into indications for surgery. After 10 years, we found following: (1) Physical was effective over 70% patients. (2) PROMs showed statistical and clinical improvement after 12 weeks did not decline years. (3) Cuff tear severity...
Meniscal deficiency has been reported to increase contact pressures in the affected tibiofemoral joint, possibly leading degenerative changes. Current surgical options include meniscal allograft transplantation and insertion of segmental scaffolds. Little is known about transplantation.To evaluate effectiveness medial setting partial meniscectomy restoring native knee loading characteristics.Controlled laboratory study.Ten fresh-frozen human cadaveric knees underwent central midbody...
