Background: The ability to predict the long-term success of surgical treatment in orthopaedics is invaluable, particularly in clinical trials. The quality of repair tissue formed 1 year after autologous chondrocyte implantation (ACI) in the knee was analyzed and compared with clinical outcomes over time. Hypothesis: Better quality repair tissue and a better appearance on magnetic resonance imaging (MRI) 1 year after ACI lead to improved longer-term clinical outcomes...

Morquio B disease (MBD) or Mucopolysaccharidosis type IV B (MPS IV B) is caused by particular GLB1 mutations specifically affecting the affinity of beta-galactosidase to keratan sulphate, resulting in dysostosis multiplex resembling Morquio A (MPS IV A) disease (GALNS deficiency). Additional neuronopathic features of GM1 II/III (juvenile/adult) gangliosidosis have been reported in some patients. Our patient/caregiver online survey was aimed at elucidating the clinical manifestations of this ultra-rare condition...

Anterior cruciate ligament (ACL) reconstruction with a bone-patellar tendon-bone autograft yields good clinical outcomes. Despite appropriate clinical outcomes, the most common complaint after reconstruction with a bone-patellar tendon-bone autograft is anterior knee pain at the donor graft sites. Synthetic bone grafts, such as beta-tricalcium phosphate (β-TCP), have been previously used to fill the bony defect in fractures as well as removal of bony tumors, and have shown positive utility in improving anterior knee pain after ACL reconstruction...

INTRODUCTION: Arthroscopic-assisted balloon tibioplasty is an emerging technology that has shown advantages in recovering depression of the articular surface. However, studies evaluating clinical outcomes between arthroscopic-assisted balloon tibioplasty and traditional open reduction internal fixation (ORIF) are sparse. This is the first randomised study to compare arthroscopic-assisted balloon tibioplasty with ORIF, and will provide guidance for treating patients with Schatzker types II, III and IV with depression of the medial tibial plateau only...

The anterior cruciate ligament (ACL) is the most commonly reconstructed ligament of the knee. Most often, the goal of surgical reconstruction is to recreate stability within the knee and prevent joint degeneration. To date, clinical studies have not demonstrated the ability of various reconstruction techniques in establishing complete knee stability when comparing rates of osteoarthritis. Rates of osteoarthritis commonly resemble those of knees which have not be reconstructed and in this light, may not demonstrate a successful outcome...

Background: When paired together, manual therapy and exercise have been effective for regaining range of motion (ROM) in multiple conditions across varied populations. Although exercise in an aquatic environment is common, research investigating manual therapy in this environment is limited. There is little evidence on AquaStretchTM an aquatic manual therapy technique, but anecdotal clinical evidence suggests its effectiveness. Purpose: To investigate the effects of AquaStretch™ on ROM and function in recreational athletes with self-reported lower extremity injury and pain...

PURPOSE: The main objective of this study was to compare quality of life and functional outcome in patients who have undergone a single-radius (SR) or multi-radius (MR) total knee arthroplasty (TKA). The secondary objective was to observe changes in knee range of movement (ROM) and standardized knee scores (KSCs) in these patients. The hypothesis was that there would be no statistically significant difference between the two patient groups in quality of life and functional outcome. METHODS: One hundred three SR TKAs were performed by a single surgeon between August 2008 and December 2012...

BACKGROUND: Osteoarthritis often results in prolonged periods of reduced physical activity and is associated with adverse health outcomes, including increased risk of cardiovascular and metabolic diseases. Exercise interventions for patients on the waiting list for arthroplasty can reduce the risk of long-term adverse outcomes by increasing activity levels. However, uptake and ongoing positive rates of physical activity in this population are low and the impact of pre-operative behaviour counselling on exercise is not known...

Functional outcomes, such as joint flexion and gait, are important indicators of efficacy in musculoskeletal research. Current technologies that objectively assess these parameters, including visual tracking systems and force plates, are challenging to deploy in long-term translational and clinical studies. To that end, we developed a wearable device that measures both physical activity and joint flexion using a single integrated sensor and magnet system, and hypothesized that it could evaluate post-operative functional recovery in an unsupervised setting...

Dysplasia epiphysealis hemimelica, also known as Trevor Fairbank disease, is characterized by asymmetrical osteochondral overgrowth of the epiphyseal cartilage. The clinical presentation of dysplasia epiphysealis hemimelica is wide and variable, depending on the site of the lesion. Herein, we describe the physical examination of a 9-year-old boy with intra-articular dysplasia epiphysealis hemimelica, in whom the symptoms were elicited on "reverse Wilson's sign": bending the knee from 70° to 120° against resistance while externally rotating the tibia...

The present systematic review and meta-analysis were conducted to find out how effective any subsequent conversion total knee arthroplasty (TKA) would be after unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) and which is better in outcomes. A rigorous and systematic approach was used. Each of the selected studies was evaluated for methodological quality. Data were extracted by the following standardized protocol: study design, level of evidence, cases enrolled, age, sex ratio, follow-up, kind of index surgery, type of index surgery, average time to failure, mode of failure, surgical data, preclinical score, post-clinical score, and major related complications...

Background: Anterior knee pain following total knee arthroplasty (TKA) remains one of the important reasons for patient dissatisfaction. The management of patellofemoral joint is controversial and a decision whether to resurface the patella or not, is important. The present study compares the clinical and radiological outcomes between patellar resurfacing and nonresurfacing in patients undergoing bilateral TKA. Materials and Methods: This is a prospective comparative study with 60 patients undergoing bilateral simultaneous TKA (120 knees) with posterior stabilized Hi flex fixed bearing knee (Zimmer, Warsaw, Indiana), by two surgeons...
