BACKGROUND: Previous work shows that young athletes after anterior cruciate ligament reconstruction (ACLR) demonstrate single-leg (SL) landing movement asymmetries at the time of return to sport (RTS); however, the effect of movement asymmetries on longitudinal knee-related function after ACLR has not been examined. Hypothesis/Purpose: The purpose of this study was to examine the effect of SL drop-landing movement symmetry at the time of RTS on knee-related function 2 years later in young athletes after ACLR...

It is claimed that weightlifting shoes with a raised heel may lead to a more upright trunk posture, and thus reduce the risk of back injuries during a barbell back squat. These proclaimed biomechanical effects have not been thoroughly investigated. The purpose of this study was to compare trunk and lower extremity biomechanics during barbell back squats in 3 foot postures.14 recreational weightlifters (7 male and 7 female) between the ages of 18-50 performed barbell back squats in 3 conditions (barefoot on a flat surface, barefoot on a heel-raised platform, and wearing heel-raised weightlifting shoes) at 80% of their 1-RM...

Total knee arthroplasty (TKA) is effective in managing end-stage degenerative joint disease. Achieving favorable clinical outcomes is predicated on proper implant alignment, sizing, and rotation as well as adequate soft-tissue balancing. Modern TKA implants are designed to address the fundamental needs of attaining stability in both flexion and extension and of optimizing patellar tracking. Measured resection and gap balancing are the two different techniques used to implant the TKA components used today. Both techniques have been validated as durable and successful, and each has unique advantages and disadvantages...

PURPOSE: We present the initial in vivo imaging results of an open architecture eight-channel parallel transmission (pTx) transceive radiofrequency (RF) coil array that was designed and constructed for static and dynamic 7T MRI of the knee and ankle joints. METHODS: The pTx coil has a U-shaped dual-row configuration (200 mm overall length longitudinally) that allows static and dynamic imaging of the knee and ankle joints at various postures and during active movements...

George F Chimento, Leslie C Thomas
PURPOSE OF REVIEW: The perioperative surgical home (PSH) is a patient-centered, physician-led, multidisciplinary care pathway developed to deliver value-based care based on shared decision-making. Physician and hospital reimbursement will be tied to providing quality care at lower cost, and the PSH model has been used in providing care to patients undergoing lower extremity arthroplasty. The purpose of this review is to discuss the rationale, definition, development, current state, and future direction of the PSH...

PURPOSE: A few studies have detected associations of post-operative tunnel enlargement with sex, age, and the timing of anterior cruciate ligament reconstruction (ACLR). The aim of the present study was to investigate the correlation between post-operative tunnel enlargement following ACLR using hamstring tendon autografts and preoperative factors. The authors hypothesized that tunnel enlargement is associated with age in patients undergoing ACLR. METHODS: One hundred and six patients (male, n = 57; female, n = 49; mean age, 26...

Chronic expanding hematoma is characterized by continuous growth of a blood collection. We analyzed the clinical features of 7 patients with chronic expanding hematomas in the extremities, with an average age of 65.6 years. All lesions occurred in the lower extremities, with 4 seen in the thigh and 3 in the knee region. Six patients had subcutaneous hematomas, while 1 was deep-seated in the thigh. The magnetic resonance features of the lesion were compatible with those of a standard hematoma. A low signal intensity on T1- and T2-weighted imaging at the pseudocapsule was also characteristic...

OBJECTIVES: To evaluate the functional and radiological results of Schatzker type II fractures treated via subchondral raft screws combined with locking plates. METHODS: Twenty-four individuals were enrolled in this study between 2010 and 2014. The depressed joint line was elevated and the defect was filled with allograft. Next, two or three subchondral screws were placed in combination with a locking plate. At the last follow-up, clinical and radiological data were recorded...

OBJECTIVE: To verify the incidence and characterize morphologically the anterolateral ligament of the knee (ALL) in cadaveric samples of the collection of the Laboratory of Anatomy of the Department of Morphology of the Universidade Federal do Espírito Santo. METHODS: Dissections and cross sections were performed for mesoscopic analysis of the anterolateral region of 15 knees preserved in 4% formalin solution in order to identify the ALL. RESULTS: After dissection of the skin and subcutaneous tissue of the knee anterolateral region, it was possible to identify the iliotibial tract (ITT), the patellar ligament and the femoral biceps tendon...

OBJECTIVE: To compare the transparent 3D computed tomography (CT) image protocol against conventional 3D-CT image-rendering protocol to assess femoral tunnel position in anatomic anterior cruciate ligament (ACL) reconstructions . METHODS: Eight knee CT scans from cadavers were analyzed by image rendering 3D-CT protocol, using Rhinoceros((r)) software. The central point of the ACL tunnel was set using the sagittal plane. Same CT scans were analyzed using transparent 3D-CT measurement protocol with OsiriX((r)) software...

OBJECTIVE: To evaluate the effects of physical activity intensity, type and duration in patients with knee osteoarthritis (KOA) . METHODS: A retrospective study of 195 KOA patients who were followed for two years after receiving educational material about KOA with or without attending classes. The patients were evaluated at baseline and 24 months. At the evaluations, the patients answered questionnaires pertaining to pain and function (WOMAC, Lequesne, VAS and SF-36); reported the intensity, duration and type of exercise performed per week; and performed the Timed Up & Go (TUG) and Five Times Sit-to-Stand (FTSST) tests ...

OBJECTIVE: To evaluate the effects of a multi-professional educational program in patients with knee osteoarthritis (KOA) . METHODS: Prospective randomized controlled trial with 195 KOA patients. One group was submitted to two-day lectures and received educational material about KOA (Class group), and the control group received the educational material only. Patients were evaluated at baseline, twelve and 24 months. At evaluation, patients answered pain and functional questionnaires (WOMAC, Lequesne, VAS and SF-36); reported the intensity of exercise per week; measured the body fat percentage, weight and height to estimate body mass index (BMI); and performed Timed Up & Go (TUG) and Five-Times-Sit-to-Stand (FTSST) tests ...

Knee osteoarthritis (KOA) is reported to have characteristic kinematics during walking. However, the relationship between Kellgren-Lawrence (K/L) score and the 3D kinematic gait of patients with medial KOA remains unclear. Here, ninety-seven patients with medial KOA and thirty-eight asymptomatic participants were involved. Patients with medial KOA were divided into early, moderate, and severe KOA based on the K/L score. Through kinematic gait analysis, we found a relationship between K/L score and 3D kinematic gait for patients...
