Anterior cruciate ligament (ACL) reinjury results in worse outcomes and increases the risk of posttraumatic osteoarthritis.
Background: Tearing an anterior cruciate ligament (ACL) graft is a devastating occurrence after ACL reconstruction (ACLR). Identifying and understanding the independent predictors of ACLR failure important for surgical planning, patient counseling, efforts to decrease risk failure. Hypothesis: Patient variables will predict ACLR. Study Design: Prospective cohort study. Methods: A multicenter group initiated study in 2002 identify outcomes, including First, control confounders, single...
Background: The long-term prognosis and risk factors for quality of life disability after anterior cruciate ligament (ACL) reconstruction remain unknown. Hypothesis/Purpose: Our objective was to identify patient-reported outcomes patient-specific from a large prospective cohort at minimum 10-year follow-up ACL reconstruction. We hypothesized that meniscus articular cartilage injuries, revision reconstruction, subsequent knee surgery, certain demographic characteristics would be significant...
Background: The predictors of anterior cruciate ligament reconstruction (ACLR) outcome at 6 years as measured by validated patient-based instruments are unknown. Hypothesis: Certain variables evaluated the time ACLR will predict return to sports function (as International Knee Documentation Committee [IKDC] questionnaire and injury Osteoarthritis Outcome Score [KOOS] Sports Recreation subscale), knee-related quality life (KOOS Related Quality Life activity level (Marx Activity Scale)....
Background Anterior cruciate ligament (ACL) graft failure is an uncommon but devastating event after reconstruction, and risk factors for are not well understood. Hypothesis Returning to a high activity level ACL reconstruction use of allograft failure. Study Design Case-control study; Level evidence, 3. Methods Twenty-one patients with were identified over 2-year period. Forty-two age- sex-matched controls the same A 1:2 matched case-control design was used evaluate type as Logistic...
Background: At the time of anterior cruciate ligament (ACL) reconstruction, there are usually concurrent meniscal and articular cartilage injuries. It is unclear if a significant difference between intra-articular injuries at primary ACL reconstruction compared with revision reconstruction. Purpose: To compare found surgery to determine associations specific findings. Study Design: Cohort study (prevalence); Level evidence, 2. Methods: Primary surgeries were identified from Multicenter...
Background: Although the prevalence of full-thickness rotator cuff tears increases with age, many patients are asymptomatic and may not require surgical repair. The factors associated pain loss function in well defined. Purpose: To determine which correlate symptomatic, atraumatic who enrolled a structured physical therapy program. Study Design: Cross-sectional study; Level evidence, 3. Methods: A multicenter group prospective, nonrandomized cohort study evaluating effects Time-zero patient...
Recent efforts to improve the results of anterior cruciate ligament (ACL) reconstruction have focused on placing femoral tunnel anatomically. Medial portal techniques facilitate drilling tunnels that are more anatomic than those made with transtibial techniques. Few studies compared clinical outcomes these two We hypothesized technique is associated decreased Knee injury and Osteoarthritis Outcome Scores (KOOS) an increased risk repeat surgery in ipsilateral knee when anteromedial...
Pain and injuries suffered by youth pitchers are ongoing concerns that have been addressed through the institution of rules recommendations regarding pitch counts rest periods. The aim our study was to see if coaches baseball in region were aware recommended guidelines they followed them.An Internet-based survey consisting 18 items including demographic information questions concerning USA Baseball Medical Safety Advisory Committee pitching sent affiliated with a local league assess their...
Background: In treatment of distal third clavicle fractures, the Neer classification system, based on location fracture in relation to coracoclavicular ligaments, has traditionally been used determine pattern stability. Purpose: To intra- and interobserver reliability fractures via standard plain radiographs agreement preferred these fractures. Study Design: Cohort study (Diagnosis); Level evidence, 3. Methods: Thirty were randomly selected from patients treated for between 2006 2011. The...
Platelet-rich plasma (PRP) has been established as safe and effective for knee osteoarthritis (OA). Another orthobiologic therapy, microfragmented adipose tissue (MFAT), gained attention because of its heterogeneous cell population (including mesenchymal stem cells). However, prospective comparative data on MFAT are lacking. Because the safety, efficacy, simplicity PRP, new therapeutics such should be compared directly with PRP.To compare patient-reported outcomes a single injection PRP...
Background Traditional nonsurgical treatment of Jones fractures has high rates delayed union, nonunion, and refracture. Internal fixation become the choice in athletes active patients. Purpose The purpose this study was (1) to review short- long-term clinical results cannulated screw (2) perform a biomechanical evaluation fatigue failure characteristics several types screws used fractures. Study Design Retrospective case series vitro study. Methods Ten male 5 female patients with fixed...
Anterior cruciate ligament (ACL) reconstruction with hamstring autografts less than 8.5 mm in diameter is associated worse patient-reported outcome scores and increased risk of revision surgery compared reconstructions performed larger grafts. One proposed solution to small autograft harvest create a hybrid graft by augmenting allograft tissue increase diameter.To compare autograft/allograft ACL reconstruction, specifically analyzing the at 2 years postoperative.Cohort study; Level evidence,...
Background: The incidence of posttraumatic osteoarthritis (PTOA) based on clinical radiographic grading criteria at 10 years after anterior cruciate ligament (ACL) reconstruction (ACLR) has not been well-defined in a prospective cohort young athletic patients. Hypothesis: Among patients, there is high PTOA ACLR. Additionally, significant difference (OA) changes (joint space narrowing and osteophyte formation) between ACL-reconstructed contralateral knees years. Study Design: Case series;...
Background: Platelet-rich plasma (PRP) is an effective treatment for knee osteoarthritis (OA). Microfragmented adipose tissue (MFAT) another orthobiologic that holds promise, but data supporting its use are limited. Previous studies showed MFAT created using the Lipogems device was equivalent to PRP via noncommercial laboratory-based processes. Purpose: To perform a comparison of commercially available and systems OA. Study Design: Randomized controlled trial; Level evidence, 2. Methods: A...
With the recent emphasis on performing open reduction and internal fixation midshaft clavicle fractures with complete displacement, comminution, >2 cm of shortening, it is important to determine reliability orthopaedic surgeons assess these variables standard plain radiographs agreement among in choosing treatment.To intra- interobserver classification via treatment fractures.Cohort study (diagnosis); Level evidence, 3.Charts patients seen by 2 senior authors from 2006 2011 were reviewed...
