Filter by:This study is a randomized controlled trial comparing total knee arthroplasty (TKA) to unicompartmental knee arthroplasty (UKA) in patients with no to moderate anteromedial knee osteoarthritis. TKA patients will receive the Zimmer Persona (Warsaw, IN) posterior cruciate retaining total knee arthroplasty, while UKA patients will receive the Biomet Oxford (Warsaw, IN) mobile bearing unicompartmental knee arthroplasty. Outcome measures will include Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Oxford Knee Score (OKS) questionnaires, as well as biomechanics and EMG analysis from the investigating gait lab. The investigators hypothesize that post-operative UKA patients will display higher clinical scores using WOMAC and OKS questionnaires, and superior biomechanical analysis measures. The investigators further hypothesize that the biomechanics data will assist in the understanding of the outcome score differential both pre- and post-operatively in both groups, as well as between-groups. Total follow up period will be two years.
The INSPYRE implant is a new range of shoulder hemi-arthroplasty device. It consists of a Pyrocarbon spherical interpositional implant and is indicated in primary surgery to relieve severe pain or significant disability caused by degenerative pathologies. The rotator cuff must be functional. The aim of this study is to prospectively collect data from consecutive series to implement a Post Marketing Surveillance plan.
LEGION™ Primary Total Knee System is CE-marked and marketed in all study regions. This study serves as post-market surveillance for LEGION™ Primary Total Knee System with the VERILAST™ bearing surface (OXINIUM™ femoral component with highly cross-linked polyethylene tibial insert). All study subjects will receive a LEGION™ Primary Total Knee System with VERILAST™ bearing surface and the results will be analysed against historical data from patients who received a Genesis II knee replacement.
Prescribing exercise for people with painful knee osteoarthritis (OA) is essential for pain management, improved function, and chronic disease prevention. Exercise that decreases joint exposure to damaging loading while eliciting adequate muscular activation for strength improvements is ideal. The purpose of this 3-arm RCT is to compare mobility, strength, pain, and MRI outcomes between the low-loading biomechanical exercise program (BE), a traditional exercise program for knee OA (TE), and a control group completing meditation classes (M).
The objective of this study is to collect outcome information on patients requiring Total Knee Replacement (TKR) in primary or revision cases and therefore receiving the LINK® Endo-Model® SL® under routine conditions.
Purpose: To determine the safety, feasibility and effectiveness (clinical and radiological) of intra-articular administration of autologous mesenchymal stem cells (MSCs) with platelet richa plasma (PRGF) in patients with knee osteoarthritis. Patients and methods Clinical trial phase I- II, randomized , multicenter , with two treatment arms and 19 patients for each group. The investigators compare the intraarticular injection of against the administration of two different doses of mesenchymal stem cells with hialuronic acid according to the following scheme: 1. Group A: 3 intra-articular injections of platelet rich plasma (PRGF®) separated by 7 days. 2. Group B: 3 intra-articular injections of platelet richa plasma (PRGF®) separated by 7 days and one with Mesenchimal stems cells. Intra-articular injection of 100 million autologous mesenchymal progenitor stem cells cultured ex - vivo (cell suspension sterile small volume (5-10 ml ) in a vehicle suitable for intraarticular injection ) followed by an intraarticular injection of platelet richa plasma (PRGF®). The treatment is completed with 2 more injection of platelet richa plasma (PRGF®) separeted by one week. In addition the investigators assess the response to intra-articular infusion of CMM analyzing the following parameters: - Clinical assessment of pain and function (Baseline, 1, 3, 6 and 12 months since treatment): VAS , WOMAC , KOOS , EuroQol, SF-16, Lequesne , WOMAC , KOOS. - Radiographic (baseline and 12 months from treatment): Femorotibial space. - Radiographic using MRI (baseline and 12 months from treatment): by assessing the number location of the lesions , cartilage thickness , signal intensity , subchondral bone alteration , volume and WORMS and dGEMRIC protocols.
The purpose of this investigation is to determine both patient-reported and performance-based outcomes, specifically muscle function and kinematic/kinetic outcomes, between four different surgical total knee prostheses in individuals following TKA. Change scores will be determined based on patient-reported outcomes, kinematic/kinetic data, knee extension strength/power, static/dynamic balance control, mobility measures and functional performance testing during functional tasks (i.e. walking, ascending/descending stairs, sit-to-stand). After evaluating the pattern of change in lower-extremity function, the investigators will be better prepared to address residual functional impairments and prognostic factors linked to maximal recovery over two years.
The primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Persona knee implants used in primary total knee arthroplasty. The assessment will include: 1. Implant survivorship based on removal of a study device. 2. Safety based on incidence and frequency of adverse events. 3. Clinical performance measured by overall pain and function, quality of life data, radiographic parameters and survivorship.
This is a randomized, placebo controlled study. The first subject is expected to be enrolled in July 2014, and the last subject is expected to complete the study by July 2015. Each subject will be provided with the PRN Joint Comfort Formula, placebo or PRN Flex Omega Benefits® combination depending on randomization (1:1:1 at each site) during the course of the study. Instructions and frequency of use will be determined by the labelling.
The primary objective of this project is to investigate, using RSA, acetabular implant migration of the OsseoTi™ G7 acetabular cup in comparison to conventional PPS coated G7 acetabular cup, and compare liner wear of thinnest available E1™ liner, allowing for the largest possible femoral head (36mm-44mm) to E1™ liner holding a 32mm femoral head in the G7 acetabular system with endpoint assessment being performed at the 2 year follow-up.
