BACKGROUND: Although previous studies have compared radiological, pain, and function scores in kinematically aligned (KA) and mechanically aligned (MA) total knee arthroplasty (TKA), no previous studies have undertaken a three-dimensional (3D) gait analysis in these groups. This study compared kinematic and kinetic variables recorded during level walking in patients at least 2 years post-surgery who underwent an MA or KA procedure. METHODS: Utilizing a 9-camera motion analysis system, gait analysis was undertaken on 29 patients (MA = 15, KA = 14)...

INTRODUCTION: Transient migratory osteoporosis (TMO) is a rare and self-limiting condition of unknown etiology. The hip joint is the most common joint to get involved in this disease followed by a knee, ankle, and foot. CASE REPORT: We report a case, which illustrates the importance of recognizing the typical clinical and radiological features of TMO of the hip and ankle, thereby allowing an appropriate form of treatment. Spontaneous resolution of symptoms occurred in the patient...

BACKGROUND: Osteoarthritis (OA) is a complex disease which can be caused by both environmental and genetic factors. A functional locus rs143383 of bone morphogenetic protein-14 (BMP-14) has been pointed out to be associated with OA etiology, but conflicting conclusions have been reached. To provide a more comprehensive conclusion about this issue, we performed this meta-analysis. METHODS: Relevant studies were searched from electronic databases including PubMed, Chinese National Knowledge Infrastructure, Embase, and Wanfang...

INTRODUCTION: Articular cartilage lesions of the hip are difficult to effectively treat. Osteochondral allograft (OCA) transplantation in the knee has been associated with long-term success, but OCA for the hip has not been extensively studied. Here, we present the clinical and radiological outcomes from a cohort of 10 patients treated with fresh OCA transplants for large osteochondral defects of the femoral head and/or acetabulum. METHODS: 10 patients who had undergone osteochondral allograft transplantation of the femoral head and/or acetabulum at our institution between 2013 and 2016 were identified from our Institutional Review Board-approved registry...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving chronic dialysis therapy. Although cinacalcet can control parathyroid function and bone turnover, preventing ectopic calcification remains challenging. Cinacalcet can also suppress PTH secretion due to parathyroid carcinoma in the same way as it does for parathyroid hyperplasia in the uremic condition. We present a case of parathyroid carcinoma partially controlled by cinacalcet, in which tumorous calcinosis was successfully resolved by total parathyroidectomy...

BACKGROUND: Patient-specific instrumentation (PSI) is attracting attention as a mechanical method of ensuring the accuracy of osteotomy during total knee arthroplasty (TKA). Few studies have focused on preoperative plans; thus, it is unclear how often initial plans have to be corrected preoperatively and intraoperatively. We investigated the frequency of corrections, the accuracy of intraoperative osteotomy, and postoperative alignment. METHODS: We analyzed 45 knees of 40 patients who underwent TKA using magnetic resonance imaging (MRI)-based PSI...

Objective: Osteoarthritis is a leading cause of disability for which there is no cure. Psychosocial-oriented treatments are underexplored. We developed and tested an intervention to build positive psychological skills (e.g., gratitude) to reduce osteoarthritis symptom severity, including pain and functioning, and to improve psychosocial well-being in patients with knee or hip osteoarthritis. Design: Two-arm randomized design with six-month follow-up. Setting: An academic Veterans Affairs Medical Center...

Individuals with cerebral palsy often exhibit crouch gait, a debilitating and inefficient walking pattern marked by excessive knee flexion that worsens with age. To address the need for improved treatment, we sought to evaluate if providing external knee extension assistance could reduce the excessive burden placed on the knee extensor muscles as measured by knee moments. We evaluated a novel pediatric exoskeleton designed to provide appropriately-timed extensor torque to the knee joint during walking in a multi-week exploratory clinical study...

BACKGROUND: Osteoarthritis (OA) is a chronic progressive disease commonly affecting the hip and knee joints. Although synthetic drugs are available and afford symptomatic relief, their side effects pose limitations to their continuous use. So, this research was focused on extracting drugs from indigenous medicinal plants that could have a beneficial effect on osteoarthritis. Dashmoolarishta is one such preparation whose effects have never been studied in comparison with recent drugs like hyaluronic acid (HA), hence this particular study was undertaken...

A lower limb-pelvis finite element (FE) model with active three-dimensional (3D) muscles was developed in this study for biomechanical analysis of human body. The model geometry was mainly reconstructed from a male volunteer close to the anthropometry of a 50th percentile Chinese male. Tissue materials and structural features were established based on the literature and new implemented experimental tests. In particular, the muscle was modeled with a combination of truss and hexahedral elements to define its passive and active properties as well as to follow the detailed anatomy structure...

BACKGROUND: Myofascial trigger points (MTrP's) are a primary source of pain in patients with musculoskeletal disorders. Nevertheless, they are frequently underdiagnosed. Reliable MTrP palpation is the necessary for their diagnosis and treatment. The few studies that have looked for intra-tester reliability of MTrPs detection in upper body, provide preliminary evidence that MTrP palpation is reliable. Reliability tests for MTrP palpation on the lower limb have not yet been performed. OBJECTIVE: To evaluate inter- and intra-tester reliability of MTrP recognition in hip and thigh muscles...
