It was well known that total knee arthroplasty could improve the previously impaired proprioception in degenerative osteoarthritis. Most current researches have been focused on the change of the proprioception. However, the evaluation of the proprioception is based on the surrogated end. Double or single limb standing balance is considered functional scale. It is very important view for the prevention of slipping down injury in evidence-based approaches for knee osteoarthritis. Unfortunately, few study have been performed for figuring proprioceptive change after surgery out. Considering the similarity between the proprioception and the standing balance and reported positive result in proprioception after total knee arthroplasty, the investigators supposed that total knee arthroplasty might give an influence on the recovery of single limb standing balance.
Common medical therapies for knee osteoarthritis are patient education, drug and physical therapy, exercise and surgery. These modalities may offer improvement but drugs and surgery carry significant risk. Manipulative therapy for KOA gives pain relief and increased function. However, research suggests addition of manipulative and soft tissue therapy (to the entire kinetic chain: lumbosacral, sacroiliac, hip, knee, ankle and foot joints), may give a better outcome. Exercise therapy is considered an effective and standard care for KOA.
The aim of this study was to determine the efficacy of methylsulfonylmethane (MSM) in treating patients with knee OA.
This proposal outlines the investigators plan to develop, evaluate and implement an accelerated in hospital and community rehabilitation following total knee arthroplasty (TKA) leading to outpatient TKA. The benefits of applying current concepts of improved postoperative analgesia and less invasive surgical technique are expected to improve objective parameters of knee function, increase patients satisfaction, while reducing health care resources requirements as compared with standard rehabilitation. The innovation of combining best practices from orthopaedic sports medicine, Anesthesia, Physiotherapy and Knee reconstruction are expected to realize this goal.
Three weekly injections of hyaluronate (Hya-Joint) are safe and well tolerated, provide rapid pain relief as early as 1 and 2 weeks after the first injection, and improve function in patients with knee osteoarthritis. The treatment effects can last for 6 months.
In this prospective study we aim to evaluate the feasibility and safety of the implantation of 40 millions MSV in knees with osteoarthritis of grade II-IV (Kellgren and Lawrence). The working hypothesis proposes that MSV antiinflammatory effect will help healing of articular cartilage degeneration to a grade enough to be objectivized by questionnaires and imaging procedures. The study of quantitative changes in structure and composition of cartilage determined by MRI T2-mapping (Cartigram ) will be performed at 6, 12 and 24 months. Pain and disability will be assessed by visual analogue scale (VAS), WOMAC, Lequesne Index and evaluation of the quality of life by Short Form 36 questionnaire (SF-36) completed at 3, 6,12 and 24 months.
An evaluation of the safety and efficacy of an herbal patch in treating osteoarthritis pain of the right or left knee.
The purpose of this study is twofold: 1) to use RSA to determine the migration patterns of the PA coated Triathlon Total Knee Arthroplasty components during the first 2 years postoperatively and thus determine the proportion of cases where adequate fixation is achieved, and 2) to use DEXA scanning to document peri-prosthetic bone mineral density changes in response to the PA coated Triathlon Total Knee arthroplasty over the first two postoperative years. In addition, gait assessment and validated outcome questionnaires will be utilized to quantify changes in functional status of subjects after surgery and migration patterns will be compared to results obtained from previous studies of uncemented total knee arthroplasty components conducted at this centre. Questions to be asked are: 1. Do the components achieve adequate fixation to the underlying bone? 2. What are the migration patterns (translations and rotations) of the PA coated arthroplasty components during the first two years postoperatively and are they different from that seen for other implants that have been studied with RSA at this institution? 3. For what proportion of implants does migration continue to increase during the two year follow-up? 4. Are inducible displacements, measured at weight-bearing follow-ups, consistent over time and do they indicate that adequate fixation has been achieved? 5. Are there changes over time in bone mineral density of peri-prosthetic bone in the PA coated Triathlon total knee arthroplasty? 6: Where do changes in bone mineral density occur? 7: Is there a significant difference in health status and functional outcome before and after total knee arthroplasty using PA coated Triathlon total knee arthroplasty components? 8: Are there changes in gait symmetry and centre of mass (COM) displacements as assessed with the Walkabout Portable Gait Monitor pre- and post-operatively and how does study gait data compare to asymptomatic gait? and finally, Question 9: Are there differences in the micromotion patterns between the when compared to other samples of knee implants in our RSA database?
Observational evidence suggests that vitamin D deficiency may have a role in the causes of osteoarthritis (OA) and there are biologically plausible mechanisms to explain this. There is, however, no evidence which shows that intervening with vitamin D supplementation can slow the progression of OA. This study is to determine if vitamin D supplementation can reduce knee pain and slow knee cartilage loss in OA patients comparing with a placebo. Use of MRI will provide sensitive measures of knee OA changes.
