Outcomes after transtibial pull-out repair for posterior meniscal root tears remain underreported, and factors that may affect outcomes are unknown. Purpose/Hypothesis: The purpose of this study was to compare patient-centered in patients <50 ≥50 years age. We hypothesized improvement function activity level at minimum 2-year follow-up would be similar among age compared with undergoing medial versus lateral repairs.Cohort study; Level evidence, 3.Inclusion criteria were aged 18 or older who...
Background: Active patients with arthritic malalignment of the knee are difficult to manage. Arthroplasty, unicompartmental or total replacement, may not be appropriate in who desire remain highly active. High tibial osteotomy has been recommended for treatment varus osteoarthritis decrease pressure on damaged medial compartment. Purpose: To determine length time gonarthrosis can avoid arthroplasty chondral resurfacing (microfracture) and opening wedge high (HTO). Study Design: Case series;...
Meniscal repair in the setting of anterior cruciate ligament (ACL) reconstruction has demonstrated superior outcomes compared with isolated meniscal repair. Limited evidence exists for effects biological augmentation repair, particularly as concomitant ACL reconstruction. Purpose/Hypothesis: The purpose this study was to compare and survivorship 2 cohorts patients: using a marrow venting procedure (MVP) intercondylar notch, We hypothesized that clinical would be improved augmentation.Cohort...
Background: Few studies have compared outcomes of Broström-Gould repair and allograft reconstruction. Hypothesis/Purpose: The purpose this study was to compare revision rates after lateral ankle ligament versus anatomic reconstruction in patients with instability. hypothesis that who underwent would similar those Study Design: Cohort study; Level evidence, 3. Methods: All surgical or the anterior talofibular and/or calcaneofibular by a single surgeon between September 2009 February 2013 were...
The purpose of this study was to document outcomes following the healing response procedure for treatment complete, proximal anterior cruciate ligament (ACL) tears in a mature, active population. Healing is an all-arthroscopic that preserves native ACL and makes use arthroscopic awl with 45-degree angle make holes femoral attachment body ACL. Patients were included IRB-approved if they > or =40 years old, had complete tear, who within 6 weeks initial injury. In 48 patients (35 females, 13...
Background: Few studies have compared outcomes after meniscus suture repair in patients younger than 40 years versus and older. Purpose: To document failure rates long-term by a single surgeon, using the inside-out technique, at minimum 10-year follow-up those Study Design: Cohort study; Level of evidence, 3. Methods: This study included all 18 or older who underwent with technique surgeon between January 1992 December 2003. Patients were divided into 2 cohorts according to age: <40...
Revision anterior cruciate ligament reconstruction (ACLR) is becoming increasingly common as the number of primary ACLR cases continues to rise. Despite this, there are limited data on outcomes revision and even less information specifically addressing differences in 1-stage versus those performed a 2-stage fashion after reconstruction.To compare outcomes, patient satisfaction, failure rates ACLR.Cohort study; Level evidence, 3.All patients who underwent between 2010 2014 by single surgeon...
Background: Activity level is a benchmark to document patient recovery; however, there lack of instrumentation measure activity specific the foot and ankle. The purpose this study was develop ankle scale (FAALS) instrument that will serve as an effective clinical tool for practitioners by assigning patients. Methods: This 4-phase with 3 rounds data collection (n = 1432). Phase 1 item generation using expert panel determine content validity (101 items). In phase 2, all items from were piloted...
Human studies suggest that heavy alcohol use may be an etiological factor contributing to the development of Alzheimer's disease (AD) neuropathology. Both disorder (AUD) and AD share common underlying neuropathology, including proinflammatory high-mobility group box 1 (HMGB1)-mediated neuroimmune signaling basal forebrain cholinergic neuron degeneration. Adolescent onset binge drinking represents a significant risk for later AUD, accumulating evidence suggests adolescent initiation induces...
Background: The purpose of this study was to determine the reliability and validity scores from Foot Ankle Ability Measure (FAAM) Activities Daily Living (ADL) Sports scales in patients who have a variety ankle injuries. Methods: All underwent surgical treatment for an injury completed FAAM ADL Sport were included ( n = 456; 192 females, 264 males). average age 47.6 years (range, 18-79 years). time follow-up 3.8 2.0-7.7 data collected prospectively reviewed retrospectively. A analysis,...
Articular cartilage defects of the knee have been shown to cause pain, swelling, decreased function, and suboptimal athletic performance. Treatment elite-level athletes presenting with full-thickness chondral continues be a challenge for orthopedic surgeons. The purpose this study was document outcomes in elite professional alpine ski racers after microfracture surgery. This approved by an institutional review board. All patients who competed races recognized International Ski Federation had...
The purpose of this study was to document outcomes following microfracture for full-thickness cartilage defects the knee in adolescents. Our hypothesis that patients aged 18 years or less would have excellent and function articular defects. This approved by Institutional Review Board. Patients < 19 old with treated between January 1992 June 2008 were identified. Surgical, demographic data, Lysholm score, Tegner activity scale, patient satisfaction collected prospectively. A total 26 (14...
The purpose of this study was to determine if short form (SF)-12 physical component would increase with unloader brace use. Patient expectations and predictors significant improvement were determined. Our hypothesis that patients braces will have increases in general health (SF-12) function (Western Ontario McMaster Universities Arthritis Index [WOMAC]). Patients enrolled institutional review board-approved prospective cohort study. They completed a self-administered questionnaire (SF-12;...
The purpose of this study was to document outcomes following microfracture articular cartilage lesions the ankle. Our hypothesis that patients who underwent ankle would have good excellent outcomes.This institutional review board approved. Patients older than 18 years surgery for Outerbridge grade 3 or 4 lesions, by a single surgeon, were included. Detailed intraoperative findings documented at surgery. completed questionnaire with Foot and Ankle Disability Index (FADI), Lysholm, Tegner,...
Background: Limited evidence exists for meniscal repair outcomes in a multiligament reconstruction setting. Purpose/Hypothesis: The purpose of this study was to assess and failure rates patients who underwent compared with but lacked tears. authors hypothesized that the associated concomitant would significantly improve from preoperatively postoperatively at minimum 2 years after index surgery. Secondarily, they cohort demonstrate similar did not have lesions time reconstruction. Study...
Osteochondral lesions of the talus are generally result trauma and often in persistent pain disability. Various treatment options have evolved to treat these challenging problems, ranging from conservative management marrow stimulation cartilage or chondrocyte transplantation. Microfracture is first line for many lesions. However, there concern that microfracture results fibrocartilage, which has inferior wear characteristics when compared with native hyaline cartilage. We describe use...
