Background: Radiological risk factors for an osteochondral fracture (OCF) associated with patellar instability are rarely studied, particularly in patients recurrent instability. Purpose: To identify specific radiological characteristics that relate to the increased prevalence of OCFs Study Design: Case-control study; Level evidence, 3. Methods: Patient data (n = 730) from Justifying Patellar Instability Treatment by Early Results (JUPITER) multicenter study were reviewed findings. Trochlear...
Background The upper and lower portions of the subscapularis muscle are independently innervated activated. Hypothesis Upper demonstrate different activation levels require exercises for rehabilitation. Study Design Controlled laboratory study. Methods Fifteen healthy subjects performed seven shoulder-strengthening exercises. Electromyographic data were collected from latissimus dorsi, teres major, pectoralis infraspinatus, supraspinatus, muscles. Results activity was greater than all except...
Factors other than surgical technique and implants impact patient outcomes following a total knee arthroplasty. The purpose of this study was to analyze the effects psychopathology on rate improvement arthroplasty in an indigent population.One hundred fifty-four consecutive patients undergoing primary for arthritis were enrolled available follow-up. Patients classified as having basis presence somatization, depression, and/or panic or anxiety disorder assessed with Patient Health...
Graft choice for pediatric anterior cruciate ligament reconstruction (ACLR) is determined by several factors. There limited information on the use and outcomes of allograft ACLR in patients. The purpose this systematic review meta-analysis was to quantify reported failure rates versus autograft patients ≤19 years age with ≥2 follow-up. We hypothesized that there would be higher compared population.PubMed/MEDLINE Embase databases were systematically searched literature regarding...
Introduction While youth sports benefits the developing athlete, athletes may also be subject to injury and subsequent return-to-sport protocols. The current criteria emphasize physical measures; however, psychological measures valuable inform providers of an athlete’s readiness. One such measure is athletic identity defined as degree which individual identifies with athlete role. To better understand in return-to-sport, this study aimed identify relationships trends between Athletic...
Genu valgum, a risk factor for recurrent patellofemoral instability, can be addressed with varus producing distal femoral osteotomy (DFO). The purpose of this study is to report 3-year clinical and radiographic outcomes on series skeletally mature adolescents traumatic instability genu valgum who underwent DFO.Consecutive patients (n=11) an isolated DFO patellar over 4-year period (2009 2012) were reviewed. All below 19 years age, mature, had ≥2 dislocations, (≥ zone II mechanical axis)...
Osteochondritis dissecans (OCD) occurs most commonly in the knees of young individuals. This condition is known to cause pain and discomfort knee can lead disability early osteoarthritis. The not well understood, treatment plans are delineated. Research Dissecans Knee (ROCK) group established a multicenter, prospective cohort better understand this disease.
Background: Treatment of anterior cruciate ligament (ACL) injuries in the adolescent population continues to be complicated by an unacceptably high rate secondary ACL injury. Purpose: To describe failure and outcomes after a hybrid pediatric reconstruction (ACLR) employing transphyseal hamstring (TPH) autograft combined with extra-articular technique using iliotibial band (ITB) autograft. Study Design: Case series; Level evidence, 4. Methods: Consecutive patients undergoing TPH-ITB ACLR...
Tibial spine fractures (TSFs) are relatively rare pediatric injuries. Postoperative arthrofibrosis remains the most common complication, with few studies having examined factors associated its development.To identify risk for and required MUA or lysis of adhesions in largest known cohort patients TSFs.Case-control study; Level evidence, 3.This was a multicenter study 249 ≤18 years old who had TSF between January 2000 February 2019. Patients were separated into cohorts based on whether they...
Background: The optimal treatment of midshaft clavicle fractures is controversial. Few previous comparative functional outcome studies have investigated these in adolescents, the most commonly affected epidemiologic subpopulation. Purpose/Hypothesis: purpose was to prospectively compare outcomes operative versus nonoperative adolescents with completely displaced fractures. study hypothesis that surgery would yield superior outcomes. Study Design: Cohort study; Level evidence, 2. Methods:...
The incidence of meniscus tears and ACL in pediatric patients continues to rise, bringing question the risk factors associated with these injuries. As are commonly repaired populations, epidemiology repairable is an important for consideration surgeons evaluating treatment options.To describe meniscal tear patterns adolescent who underwent repair across multiple institutions surgeons, as well evaluate relationship between age, sex, body mass index (BMI) their effect on prevalence, type,...
This study aimed to compare the biomechanical strength and stiffness of native posteromedial posterolateral meniscotibial ligament complex (MTLC) suture anchor repair MTLC. Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: MTLC (n = 14), 5), 5). Load failure measured for all conditions. The load construct significantly higher than that (p < 0.01). had a greater 0.03). Posterolateral similar between tissue suture-anchor repair....
The prevalence of labral tears in asymptomatic active adults has been reported, but the and other incidental hip lesions pediatric population remains unclear. purpose this study was to determine abnormalities detected on 3T MRI an with no symptoms compare found children adolescents who underwent for a hip-related condition. After IRB approval, patients self-reporting as athletes presenting isolated, acute-onset knee pain requiring were prospectively recruited undergo their contralateral...
Background: Patellofemoral instability is a common problem, and medial patellofemoral ligament (MPFL) reconstruction standard treatment approach for recurrent instability. The accurate restoration of anatomy in MPFL essential. While coronal-plane the patellar insertion has been previously reported, sagittal-plane not widely studied. Purpose: To evaluate sagittal pediatric specimens to guide future anatomic reconstruction. Study Design: Descriptive laboratory study. Methods: A total 11...
Background: Management approaches and surgical techniques for patellofemoral instability (PFI) continue to lack clear clinical guidelines indications. Medial ligament reconstruction (MPFLR) is the most frequently used procedure; however, variation in technique remains significant, particularly skeletally immature patients. Purpose/Hypothesis: The purpose of this study was examine variations MPFLR patients as represented by 20 orthopaedic surgeons with different experience levels specialty...
Prior studies in porcine and adult human bone suggest that suture fixation is superior to screw of pediatric tibial spine fractures (TSFs). However, we have previously demonstrated 2-suture repair was biomechanically comparable with 2-screw cadaveric knees. To evaluate whether TSF sutures attached anchors placed stronger metadiaphyseal would produce constructs. Controlled laboratory study. Six knees were acquired. We applied the same creation protocol used our previous study, then repaired...
Background: Osteochondritis dissecans of the knee (KOCD) may be a source pain in active, skeletally immature patients. An association between condylar lesion location and lower-extremity coronal plane malalignment has been established, but clinical implications have poorly understood. This study aimed to confirm high rate KOCD variation demographic characteristics, presentation features, disease severity those with without malalignment. Methods: Prospectively collected clinical, demographic,...
