Filter by:The aim of this double-blinded controlled study is to assess clinical efficacy and safety of intra-articular polyacrylamide hydrogel with ions of silver in comparison with placebo (0.9% sodium chloride solution) in Kellgren Lawrence radiological grade II-III knee osteoarthritis
The purpose of the study is to compare the clinical outcome after two total knee endoprosthesis designs Medacta GMK Sphere and Medacta GMK PS. Primary outcome measures KOOS, Forgotten Knee Score and range of motion. Single-center, randomized trial
This study will be an open-label trial to determine the functional effects of bilateral IA injections of Zilretta into knee joints of 70 subjects with bilateral KL grade 2-4 symptomatic knee osteoarthritis (OA). Measurement and evaluation of outcomes at baseline, 6, 12 and 24 weeks will allow assessment of short and long-term effects, consistent with Osteoarthritis Research Society International (OARSI) and Outcome Measures in Rheumatology (OMERACT) recommendations.
The purpose of the study is to determine if knee replacement performed using Journey II implant is different from two other standard-of-care knee replacements using Stryker and Zimmer in terms of knee movements and forces, walking patterns, pain, and function after surgery.
Total knee arthroplasty (TKA) is a surgical procedure applied as a common solution to overcome limitations produced by advanced stages of severe gonarthrosis. The procedure has high prevalence, high associated costs, and is considered to be cost-effective. Rehabilitation is essential to optimize outcomes. However, in clinical practice, the length of rehabilitation for each patient may be highly variable, and the programmed times may lack the necessary objectivity. Current limitation of resources and increasing prevalence make essential to generate strategies to optimize surgical results, so that the use of resources of the health system is efficient without detriment to the patient's benefit. For this purpose, objective and pragmatic information must be available, and should be based on scientific evidence in order to assist in making clinical decisions. Indeed, a number of demographic, biomedical and psychosocial factors have been identified as predictors of TKA results (i.e weight, age, expectations...). Some of them have been associated with the need for hospital resources after surgery. However, most researches base their predictions in retrospective studies, which are limited in the type of variables that can be used (clinic history), quality of registries, and limitations of retrospective designs. On the other hand, most of prospective researches base their predictions in a limited number of outcomes. To overcome this limitations, this project has been designed as a prospective observational study with two observations of each patient. - The primary goal is to implement a multi-variable prediction model of TKA outcome, so that the procedure become optimal in two aspects : patient recovery (social and economic benefit) and use of health system resources (economic benefit). The implementation requires a processing of the information sampled through various algorithms and innovative data processing in this field, based on data mining and machine learning techniques. This will be used in search of the model with the greatest predictive capacity. - As a secondary objective, information extracted from patients both in the final stages of the condition, and in the medium term after the intervention will allow to study the functional and psychosocial reality of the subjects with knee osteoarthritis.
The aim of the study is to investigate and compare the effect of balance and proprioception exercises with strengthening exercises on muscle strength, pain, proprioception, function and quality of life in knee osteoarthritis patients.
Total knee replacement surgery is commonly performed for patients suffering from severe knee osteoarthritis. However, 20% of patients continue to experience pain after surgery. There is currently no standardized pain management protocol for pain after total knee replacement. Cooled radiofrequency ablation has been used successfully to alleviate spin-related pain and has recently been approved by the FDA to treat chronic knee arthritic pain. This pilot study aims to collect preliminary data on the use of cooled radiofrequency ablation in patients undergoing total knee replacement.

The clinical efficacy of hyaluronic acid or corticosteroid injections has been reported, but effects are short lived. This has led to the development of additional injection options such as autologous derived blood products which have been documented to alleviate symptoms related to knee osteoarthritis, with recent comparative studies suggesting a greater, long-lasting effect with these blood derived products like platelet rich plasma (PRP) [2-8]. One clinically-developed preparation of platelet rich plasma, named autologous conditioned plasma (ACP), has randomized controlled trial data proving efficacy [4,9]. Clinical use of platelet rich plasma for knee arthritis typically involves a 3-injection series over 3 weeks, i.e. an injection once a week for three weeks. The main objective of this study is to determine if hyaluronic acid (HA) injected at the same time as autologous conditioned plasma (ACP), a leukocyte-poor platelet rich plasma product, will improve the performance of ACP in the treatment of symptomatic knee osteoarthritis. It is hypothesized that the injection of hyaluronic acid will improve the efficacy of ACP.
The purpose of this study is to determine the effect of Biofreeze® versus a placebo on walking gait characteristics and pain during walking in individuals with bilateral knee osteoarthritis (OA).
