CONTEXT: Training exposure has been associated with injury epidemiology in elite youth soccer, where lower limb musculoskeletal screening is commonly used to highlight injury risk. However, there has been little consideration of the relationship between lower limb screening and the loading response to soccer activities. OBJECTIVE: To quantify the efficacy of using screening tests to predict the loading elicited in soccer-specific activities, and to develop a hierarchical ordering of musculoskeletal screening tests to identify test redundancy and inform practice...

Nitinol stents are widely used for the treatment of peripheral arterial diseases in lower extremity arteries and have shown different clinical outcomes depending on implanted arterial segments. We aimed to compare histopathological responses to nitinol stents in femoral artery (FA) with those in femoropopliteal artery (FPA), which is markedly bended during knee flexion. A single nitinol stent was implanted in FA and FPA of 21 domestic swine. The stented vessels were angiographically assessed and then harvested for histopathology at 1 and 3 months after implantation...

PURPOSE: Anterior cruciate ligament (ACL) repair was first described in the mid 1900's. However, due to poorly selected patients led to unsatisfactory early results. We aim to study the outcome of ACL repair in a carefully selected cohort. METHODS: Thirteen consecutive patients of acute Type 1 (proximal ACL avulsion) were treated with arthroscopic ACL repair using a suture pull out technique. At the latest follow-up the patients were evaluated for Lysholm score, KT-1000 measurement and clinical assessment for any laxity...

BACKGROUND: Henoch-Schonlein Purpura (HSP) is one of the most common vasculitides of childhood, with 10-20 cases per 100,000 children. It frequently occurs following an infectious trigger and involves IgA and C3 deposition in small vessel walls. HSP is characterized by palpable purpura plus IgA deposition on biopsy, arthritis/arthralgia, renal involvement (hematuria and/or proteinuria), and/or abdominal pain. It is not generally recognized as a cause of dilated coronary arteries. CASE PRESENTATION: We describe the first reported case of HSP presenting with dilated coronary arteries...

Background: The Musculoskeletal Readiness Screening Tool (MRST) was developed in an effort to consistently predict injury among military personnel. Current injury prediction tools have not consistently predicted injury in this population. The MRST is comprised of the weight bearing forward lunge, modified deep squat, closed kinetic chain upper extremity stability test (CKCUEST), forward step down with eyes closed, stationary tuck jump, unilateral wall sit hold, and subjective, individual perceived level of risk for injury...

The Anatomy Lesson of Willem Röell, painted by Cornelis Troost in 1728, should be considered a group portrait of the Amsterdam Guild of Surgeons. Professor Röell, praelector anatomiae (lecturer in anatomy) of the Surgeons' Guild, was portrayed while performing an anatomical dissection of the knee joint in the corpse of an elderly man. The three surgeons in the painting, dressed in fashionable suits, held important positions as governors of the Guild. The Guild assistant, holding a box containing surgical instruments, is standing in the background (left corner)...

PURPOSE: Synovial cyst of knee cruciate ligament (SCKCL) is a rare condition but can cause severe knee pain. The understanding of its etiology is relatively poor. This current study aimed to elucidate the pathogenesis of SCKCL based on a series of histo- and cytopathological examination. METHODS: Ten SCKCL patients who underwent arthroscopy were enrolled, among five patients claimed past knee injury. Hematoxylin & eosin staining was conducted to the cyst wall tissue sections and Papanicolaou staining to the cyst fluid smear...

The anterior cruciate ligament (ACL) is a dynamic structure composed of distinct bundles that function synergistically to facilitate normal knee kinematics in concert with bony morphology. Characterized by individual uniqueness, the ACL is inherently subject to both anatomic and morphological variations as well as physiologic aging. No locus on the lateral wall of the intercondylar notch is truly isometric through full range of motion, suggesting the ACL is a dynamic structure. Future studies should explore dynamic ACL behavior in vivo...

PURPOSE: The purpose of this study was to (1) map the length changes of the medial wall of the lateral femoral condyle (MWLFC) with respect to various points about the tibial anterior cruciate ligament (ACL) footprint to determine the area that demonstrates the least amount of length change through full range of motion and (2) to identify a range of flexion that would be favorable for graft tensioning. METHODS: Six fresh-frozen cadaveric knees were obtained from screened individuals with no prior history of arthritis, cancer, surgery, or any ligamentous knee injury...

PURPOSE: Mobile-bearing Oxford unicompartmental knee arthroplasty has been used widely and successfully; however, there is no previous research on the intraoperative bearing movement. The purpose of this study was to characterise intraoperative bearing movement and investigate whether bearing movement relates to component positions, bearing size, intraoperative rotational kinematics and clinical results. METHODS: A trial tibial component, which was scaled every 2 mm, was used to measure the intraoperative movement of the mobile bearings...

PURPOSE: The purpose of this study was to reveal the correlation between femoral tunnel length in anatomical single-bundle anterior cruciate ligament (ACL) reconstruction and body size and/or knee morphology. METHODS: Thirty-one subjects undergoing anatomical single-bundle ACL reconstruction were included in this study (20 female, 11 male; median age 46, 15-63). Pre-operative height, body weight, and body mass index (BMI) were measured. In pre-operative magnetic resonance imaging, the thickness of the quadriceps tendon and the whole anterior-posterior (AP) length of the knee were measured using the sagittal slice...

Blasiak A, Whyte GP, Matlak A, Brzóska R, Sadlik B. Morphologic properties of cartilage lesions in the knee arthroscopically prepared by the standard curette technique are inferior to lesions prepared by specialized chondrectomy instruments. Am J Sports Med. 2018;46(4):908-914. (Original DOI: 10.1177/0363546517745489) There is an error in the Abstract of this article. The Conclusion of the Abstract currently reads: Arthroscopic cartilage lesion preparation with SC instruments results in superior perpendicularity of surrounding cartilage walls to subchondral bone and greater consistency of debrided lesion depth, as compared with the standard debridement technique with curettes...

BACKGROUND: In contrast to postdischarge arthroplasty readmission rates, the unscheduled reattendance burden to primary care is under-reported. Understanding reasons for reattendance would allow for implementation of strategies to reduce this burden. The present study aims to quantify the out-of-hours (OOH) general practitioner and emergency department (ED) service reattendance burden and readmission rate after primary total hip arthroplasty and total knee arthroplasty, with estimation of the associated costs...

There have been many innovations in the field of ACL-reconstruction over the years, including the FlipCutter® and TightRope® system (both from Arthrex Inc.). The FlipCutter® is a combined guide pin and reamer that allows minimally invasive socket-creation from the inside out, especially in difficult-to-reach areas. The TightRope® is a further development of the well-known Endobutton™ (Smith & Nephew plc) that consists of a four-point knotless locking system. Its main advantage is its adjustability, which makes it possible to fill the entire bone socket with the graft without any empty space...

Blunt trauma to the anterior knee typically results in a contusion or fracture of the patella. Additionally, injury to the extensor mechanism may come from a partial or full disruption of the patellar or quadriceps tendon. A professional baseball player suffered an injury to his knee after he collided with an outfield wall. Acute swelling in the suprapatellar soft tissues concealed a palpable defect, which initially was suspected to be an injury to the quadriceps tendon. Magnetic resonance imaging of the knee revealed an intact extensor mechanism; moreover, a fracture of the subcutaneous fat anterior to the quadriceps tendon was evident and diagnosed as a fat fracture...
