The origin of cells that contribute to tendon healing, specifically extrinsic epitenon/paratenon vs. internal fibroblasts, is still debated. purpose this study determine the location and phenotype healing a central patellar defect injury in mouse. Normal adult consists scleraxis-expressing (Scx) fibroblasts situated among aligned collagen fibrils. body surrounded by paratenon, which thin layer do not express Scx fibers oriented circumferentially around tendon. At 3 days following injury,...
The present study evaluates the inter- and intraobserver reproducibility of clinical examination glenohumeral laxity in unanesthetized shoulder. Forty-three asymptomatic Division I collegiate athletes underwent bilateral shoulder initially again after 3 months. Translation humeral head on glenoid fossa anterior, posterior, inferior directions was graded by four physicians who were blinded to their own previous grading that other examiners. Overall 46%. When grades 0 1 equalized, overall...
To determine the degree of shoulder translation in uninjured athletes, we examined 76 Division I collegiate athletes (44 women and 32 men) for passive range motion both shoulders knee elbow hyperextension. Translation was based on a scale 0 to 3+. Shoulders with symptoms pain or history instability dislocation were excluded from this study. Forty-six had anterior translation, 75 1+, 31 2+. Thirteen posterior 56 83 Thirty-eight inferior 105 9 No 3+ any direction. Twenty-four 12 men women,...
Treatment for idiopathic adhesive capsulitis or frozen shoulder of the is controversial. The hypothesis study that intra-articular corticosteroid injection in early stages will lead to a razpid resolution stiffness and symptoms. This retrospective cohort only patients with stage 1 2 capsulitis. diagnosis was made by history physical examination when other causes pain motion loss were eliminated. Stage defined as significant improvement normalization following injection. included who had...
Abstract Tendon injuries are major orthopedic problems that worsen as the population ages. Type‐I (Col1) and type‐II (Col2) collagens play important roles in tendon midsubstance tendon‐to‐bone insertion healing, respectively. Using double transgenic mice, this study aims to spatiotemporally monitor Col1 Col2 gene expression, histology, biomechanics up 8 weeks following a full‐length patellar injury. Gene expression histology were analyzed weekly for 5 while mechanical properties measured at...

ABSTRACT Musculoskeletal injuries greatly affect the U.S. population and current clinical approaches fail to restore long‐term native tissue structure function. Tissue engineering is a strategy advocated improve tendon healing; however, field still needs establish biological benchmarks for assessing effectiveness of tissue‐engineered structures. Investigating superior healing models, such as MRL/MpJ, offers opportunity first characterize successful then apply experimental findings therapies....
Objective— To report clinical findings and outcome in dogs diagnosed with medial shoulder instability (MSI) treated radiofrequency‐induced thermal capsulorrhaphy (RITC). Study Design— Retrospective study. Animals— Dogs (n=43) MSI. Methods— Medical records from consecutive cases MSI based on orthopedic examination, palpation of abduction angles, arthroscopic were used to determine long‐term (≥1 year) RITC. Results— Forty‐three met the criteria for inclusion; 2 had bilateral The most common...
Platelet-rich plasma (PRP) is a blood product that contains several growth factors and active proteins. PRP thought to be used autologously assist in the repair of injured tissues as well treat pain at site injury. The mechanism behind regenerative medicine has been investigated includes identification concentration released exosomes. benefits have highly recommended are widely orthopaedics sports medicine, including skeletal muscle. This current report summarizes some more recent studies...
Abstract Objective To identify specific transcription factors that are activated in the cartilage tissue of osteoarthritis (OA) patients and involved expression matrix metalloproteinase 1 (MMP‐1). Methods DNase I footprint electrophoretic mobility shift assays were performed to active elements MMP1 promoter interact with it. The relative abundance factor was determined by immunohistochemical analysis. role serum amyloid A–activating (SAF‐1) MMP‐1 assessed transient transfection assay...
The cellular, biochemical, biomechanical, and histologic effects of radiofrequency-generated heat on osteoarthritic cartilage were assessed. Articular explants (n=240) from 26 patients undergoing total knee arthroplasty divided based Outerbridge grade (I or II/III) randomly assigned to receive no treatment (controls) monopolar bipolar radiofrequency at 15 30 W. Both potentially beneficial harmful articular noted. It will be vital correlate data in vitro vivo study thermal chondroplasty...
Objective Superolateral Hoffa's fat pad (SHFP) edema is a previously described magnetic resonance (MR) finding located between the patellar tendon and lateral femoral condyle. The purpose of our study was to determine prevalence clinical significance SHFP in female collegiate volleyball players. Materials Methods Sixteen players were consented for bilateral knee evaluations which consisted history, physical examination MR imaging. Each reviewed presence edema, 6 maltracking measurements...
