The purpose of this study was to examine a young athletic population update the data regarding epidemiology and disability associated with ankle injuries. At United States Military Academy, all cadets presenting injuries during 2-month period were included in prospective observational study. initial evaluation an extensive questionnaire, physical examination, radiographs. Ankle sprain treatment supervised rehabilitation program. Subjects reevaluated at 6 weeks months subjective assessment,...
The causes of noncontact anterior cruciate ligament injury remain an enigma.To prospectively evaluate risk factors for injuries in a large population young athletic people.Prospective cohort study.In 1995, 1198 new United States Military Academy cadets underwent detailed testing and many parameters were documented. During their 4-year tenure, all that occurred identified. Statistical analyses used to identify the may have predisposed injuries.Among 895 who completed entire study, there 24...
Varying concentrations of blood components in platelet-rich plasma preparations may contribute to the variable results seen recently published clinical studies. The purposes this investigation were (1) quantify level platelets, growth factors, red cells, and white cells so-called one-step (clinically used commercial devices) two-step separation systems (2) determine influence three separate draws on resulting plasma.Three different (PRP) methods (on samples from eight subjects with a mean...
Background Despite numerous surgical techniques described, there have been few studies evaluating the biomechanical performance of acromioclavicular joint reconstructions. Purpose To compare a newly developed anatomical coracoclavicular ligament reconstruction with modified Weaver-Dunn procedure and recently described arthroscopic method using ultrastrong nonabsorbable suture material. Study Design Controlled laboratory study. Methods Forty-two fresh-frozen cadaveric shoulders (72.8 ± 13.4...
Recently acromioclavicular joint reconstruction techniques have focused on anatomic restoration of the coracoclavicular (CC) ligaments. Such involve creating bone tunnels in distal clavicle and coracoid.To define anatomy human coracoid process scapula, order to guide surgeons reconstructing CC ligaments.Descriptive laboratory study.One hundred twenty (60 paired) cadaveric clavicles corresponding scapulae (mean age +/- standard deviation, 48.3 16.6 years) devoid soft tissue were analyzed (dry...
Background: Most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome; however, revision may be limited due previously used grafts. Hypotheses: Autograft use would result in increased sports function, activity level, and decreased osteoarthritis symptoms (as measured by validated patient-reported outcome instruments). failure reoperation rate 2 years after ACL reconstruction. Study Design: Cohort study; Level of...
Background Recent technical improvements have led the way to a resurgence of single-incision approach for repair distal biceps tendon injuries. There has been no biomechanical evaluation all these techniques with comparison standard 2-incision bone tunnel technique. Hypothesis will be difference under cyclic loading and ultimate failure between technique, suture anchor repair, interference screw, EndoButton ruptures. Study Design Controlled laboratory study. Methods Sixty-three fresh-frozen...
Fifty-one patients with 54 meniscal repairs were evaluated second-look arthroscopy and physical examination at an average of 11 months (range, 4 to 30) after repair. Thirty-five (65%) completely healed 9 incompletely healed, for overall satisfactory healing rate 81% (44 repairs). Ten did not heal (19%). An anterior cruciate ligament reconstruction combined repair increased healing--36 40 (90%) versus 8 14 (57%) in stable knees. Rim width was a significant factor; no rim greater than mm...
Peterson's pioneering experience with the first clinical application of autologous chondrocyte implantation showed improvement in outcomes, durable as much 11 years, for a difficult patient population. An assessment general applicability this technology United States requires long-term, multicenter followup. The purpose cohort study was to assess outcomes patients treated lesions distal femur. Modified 10-point scales Cincinnati knee rating system were used measure assessments at baseline...
Background: Clinical application of platelet-rich plasma (PRP) in the realm orthopaedic sports medicine has yielded variable results. Differences separation methods and variability individual may contribute to these Purpose: To compare effects different PRP on human bone, muscle, tendon cells an vitro model. Study Design: Controlled laboratory study. Methods: Blood collected from 8 participants (mean ± SD age 31.6 10.9 years) was used obtain preparations. Three were used: a single-spin...
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...
Altering the tibial slope in an anterior cruciate ligament-deficient knee has been shown to affect anterior-posterior translation. The effects on articular contact pressure of altering during a high osteotomy are unknown.Performing opening wedge midaxial line will increase slope. Increasing with redistributes tibiofemoral joint pressures onto posterior plateau.Controlled laboratory study.Medial osteotomies were performed, and plate fixation known diameter inset was placed along medial tibia...
The factors that lead to patients failing multiple anterior cruciate ligament (ACL) reconstructions are not well understood.Multiple-revision ACL reconstruction will have different characteristics than first-time revision in terms of previous and current graft selection, mode failure, chondral/meniscal injuries, surgical charactieristics.Case-control study; Level evidence, 3.A prospective multicenter database was utilized for the time period from March 2006 June 2011. Patients were divided...
Background: Many reconstructions of acromioclavicular (AC) joint dislocations have focused on the coracoclavicular (CC) ligaments and neglected functional contribution AC deltotrapezial fascia. Purpose: To compare modifications previously published methods for direct reconstruction in addition to a CC reconstruction. The hypothesis was that there would be significant differences within variations surgical reconstructions. Study Design: Controlled laboratory study. Methods: A total 24...
A baseline computerized cognitive assessment was completed by 483 military cadets before their initial school year. Fourteen concussed during physical education boxing were retested <1 hour after injury and again on return to full activity 4 days later. Compared with testing, postinjury performance simple reaction time continuous tests significantly slowed, even experienced resolution of symptoms cleared resume activity. These findings may be relevant current concussion management guidelines.
The purpose of this study was to determine the correlation between Lysholm knee score and Single Assessment Numeric Evaluation method. Between March 1995 December 1996, 201 followup examinations were performed on 130 college age patients who had undergone anterior cruciate ligament reconstructions. These divided into five routine categories: 3 months, 6 1 year, 2 years, greater than years. from each patient's questionnaire correlated with his or her rating, as determined by written response...
Bracing after anterior cruciate ligament reconstruction is expensive and not proven to prevent injuries or influence outcomes.To determine whether postoperative functional knee bracing influences outcomes.Prospective, randomized, multicenter clinical trial.One hundred volunteers from the 3 US service academies with acute tears were randomized into braced nonbraced groups. Only those subjects treated surgically within first 8 weeks of injury included. Patients chondral injuries, significant...
