Active clinical trials for "Osteoarthritis, Knee"

The aim of the present study is to evaluate the effects of WB-EMS application in overweight women and men with knee osteoarthritis, with special consideration of sustainability. In this randomised controlled trial 72 overweight patients with knee osteoarthritis aged 40-70 years will be included and randomly assigned to two groups (WB-EMS vs. control group (CG)). The intervention group will perform six WB-EMS sessions/month of 20 min for 6 months. An intermittent low frequency WB-EMS-protocol with an impulse phase of 6s, followed by an impulse break of 4s will be applied. The control group will undergo a tailored physiotherapy program of 6 sessions defined as usual care. In addition, both groups will complete a self-management training programme for osteoarthritis of 6 sessions over 12 weeks.

In the majority of patients with osteoarthritis of the knee the disease originates in the medial compartment. There are two different approaches to replacing this arthritic area. Some surgeons feel that it is always best to replace both the knee compartments with a Total Knee Replacement (TKR). Others feel it is best to replace just the damaged component of the knee with a Unicompartmental Knee Replacement (UKR). There is little agreement amongst knee surgeons. Both interventions are established and well documented procedures, yet little evidence exists to support either practice. Each intervention is considered standard care. There exists little evidence, however, to prove the clinical and cost effectiveness of either management option. The aim of the Total or Partial Knee Arthroplasty Trial (TOPKAT) will be to assess the clinical and cost effectiveness of Total Knee Replacements versus Unicompartmental Knee Replacements in patients with medial osteoarthritis. This will be examined using an appropriate patient base and long term assessments. The trial has a combined device/expertise based allocation depending on the local situation. Surgeons who are in equipoise and have sufficient experience to perform both TKR and UKR, randomisation and allocation can be based on "device" (UKR or TKR). The same surgeon will perform the operation for both arms of the study. For surgeons who hold a preference for one treatment over the other, an "expertise" based randomisation will then occur. UKR surgeons will work alongside TKR surgeons. Patients recruited to the study from these sites will be randomised to one of the treatment options and treated by the appropriate surgeon. In such cases the patient is internally referred to the other surgeon's operating list. Patients will be recruited by their consultant knee surgeons in collaboration with the local research team. TOPKAT are hoping to recruit 500 patients altogether, with 250 per arm of the trial.

This study is a prospective, randomized trial to compare patient outcomes of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) for the treatment of medial compartment osteoarthritis.

The purpose of the present pilot study is to evaluate, through gait analysis and rating scales, the functional outcome during the execution of motor tasks with high functional demand such as walking on an unstable surface, stair ascent and descent, maximal knee flexion under load (lunge) on a sample of 20 subjects candidates to cemented total knee arthroplasty with MP design at the Orthopedic and Traumatology Clinic 2nd of the Rizzoli Orthopedic Institute. The parameters obtained will be compared with the parameters of healthy subjects comparable by age and Body Max Index (BMI) already acquired at the Movement Analysis Laboratory of the Rizzoli Orthopedic Institute, where the study will be conducted. On the day of admission to the ward (generally the day before the scheduled surgery), the enrolled patients will undergo the evaluation scales and gait analysis at the Institute's Movement Analysis Laboratory. The patients will be operated by the team of the Traumatological Orthopedic Clinic 2nd through the implantation of a cemented total knee prosthesis MP (Evolution medial-pivot knee system, MicroPort Orthopedics). Anterior knee access with medial para-patellar capsulotomy and standard instruments will be used according to current standards of good clinical practice. In the post-operative period, patients will carry out post-surgical rehabilitation following normal clinical practice. The patients will be re-evaluated at a 6-month follow-up through gait analysis and evaluation scales on the occasion of the control visit that takes place, according to the normal clinical practice at the Institute.

Valgus high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are established treatment options for patients with medial compartmental osteoarthritis (OA) of the knee.However, the clinical outcomes of these treatment modalities for unicompartmental OA have become subjects of debate.

Compare knee flexion after cruciate-retaining and cruciate substituting Total Knee Arthroplasty.

The principal objective of this study is to compare migration patterns between the Attune and Attune S+ PS knee systems using model-based RSA over the first 2 post-operative years. Secondary objectives include; comparison of 2-year migration values against published thresholds for adequate short-term fixation, quantify changes in functional and health status of subjects following surgery and compare between study groups, and assess occurrences of complications following surgery.

The aim of this study is to evaluate, over a 2 year period, the migration pattern, function and the possibility of anatomical reconstruction of a relatively new total knee arthroplasty (TKA) concept, the Persona. Sixty patients will be randomized into 2 groups of 30 patients each, with one group receiving the Persona TKA with a conventional Cruciate Retaining (CR) polyethylene articular surface and the other group with a newly developed Medial Congruent (MC) articular surface. Patients will be followed up with Radiostereometry (RSA), conventional radiography, outcome questionnaires, clinical evaluation and Computer Tomography (CT). The migration pattern of the components will be evaluated as well as the degree of anatomical reconstruction and clinical result. We plan also to do a 5 year follow-up of the patients with RSA and PROMS.

RCT comparing UC and PS TKA

This study is to determine how 8-week Tai Chi intervention alters plasma endocannabinoid and its receptors in monocytes/marcrophages, plasma oxylipinds, plasma brain-derived neurotrophic factor, brain white matter connectivity/efficiency, and functional/clinical outcomes in women with knee OA.
