The Effect of Exercise Training on Muscle Mass in Patients With Total Knee Arthroplasty

Knee OsteoarthritisArthropathy of Knee Joint

Background: Total knee arthroplasty (TKA) is one of the most common operations in orthopedics. After surgery, the decline of bone mineral density and muscle mass was proved, oral bisphosphonate is commonly used to prevent BMD loss in clinic treatment, however, the loss of muscle mass can only be maintained with exercise intervention. The goals of TKA rehabilitation should be based on control pain, improve ambulation, maximize the range of motion, develop muscle strength, and provide emotional support. We planned to find out a potential adjuvant effective option in muscle mass for the management of post-TKA. Literature suggested that exercise training has been found to have the considerable effect on TKA. However, no suitable exercise prescription was established on the scientific basis. The current study aimed to find out a potential treatment mode. Study Rationale: This project will be performed for consecutive three years, the patients with post-TKA patients are managed with the treadmill exercise training in the first year. In the second year, resistance exercise is prescribed. In the third year, eccentric exercise plus resistance training will be arranged in the exercise group. We will analyze the data of the three years and cross-comparative analysis. A prescription of exercise training, a period of 24 weeks each year, 3 times a week, for each 10 minutes warm-up, 40 minutes exercise training, and 10-minute cool down for exercise prescription Study Objectives: To investigate the effect of long-term exercise training, eccentric and resistance exercise on muscle mass in patients with total knee arthroplasty. To monitor the performance index included: physiological indices, muscle mass, ambulation and the quality of life index. Study Design Duration of Treatment: Total of 6-month exercise intervention in each year. The number of Planned Patients: 35 subjects in each control and exercise group in one year, the total of 210 subjects in three years. Investigational Product: Automated biochemistry analyzer, Biospace Inbody 7.20 Analysis of body composition instrumentation; Dual Energy X-ray Absorptiometer (DEXA), isokinetic muscle strength measurement, VICON to analysis ambulation, functional fitness, the questionnaire including SF-36, KOOS and VAS pain score. Endpoints: Data collection in pre-surgery, 3 months, 6 months, 9 months and 12 months after surgery.

The Effect of High Impact Exercise on Bone and Articular Cartilage in Post-menopausal Women

OsteoporosisPostmenopausal3 more

Osteoarthritis (OA) and osteoporosis (OP) affect large numbers of the population. Around 8 million people in the UK are affected by OA and over 300,000 people present with fragility fractures in the UK each year. High impact exercise has been shown to improve markers of bone health but the effect of this exercise on the cartilage is less well understood. A six month, one leg, exercise program based on hopping will be carried out by a group of post-menopausal women. Post-menopausal women are particularly at risk from OP and the research should give information on the feasibility of this type of exercise program in this age group and the effect on cartilage. Participants will be aged between 55 and 70 (at least five years post menopause) with no conditions that would limit their ability to complete the exercise program. To assess changes in participants' cartilage and bone properties they will be asked to attend several meetings at Loughborough University. Before and after the exercise program participants will have bone density scans and MRI scans of the knee joint. A subset (n=4) will undergo high resolution bone scans that can demonstrate changes in bone structure. The intervention is a home based exercise programme lasting approximately 10 minutes per day. Initially this will be individualised to each participant with the end goal being daily exercise sessions. The programme will last for six months with supervised sessions offered throughout the trial. Using an intervention affecting just one leg will allow the research team to use the other leg as a control. The research team hypothesise that in a population of post-menopausal women, a six month, unilateral exercise intervention will improve bone mineral density at the proximal femur with no negative effects on articular cartilage.

Medico-economic Study of Patient Matched Cutting Blocks (Ancillary) MyKnee ® LBS During Knee Arthroplasty...

Osteoarthritis

Total knee arthroplasty represents over 70 000 surgical procedures per year in France, increasing about 10% each year since the early 1990s. Clinical experience shows a strong rate of success on pain relieve and improvement of knee articular function for these patients. Longevity of the implants had been proved to depend on the biomechanical design and implantation techniques, particularly the bone cuts during the surgery. To improve the precision of these cuts, the patient matched cutting blocks developed by Medacta company allows to adapt bone cuts to the patient anatomy improving the reliability of these procedure. A reduction of surgical time and bleeding would be another benefit expected with this type of ancillary. The objective of this study is to demonstrate the advantage of patient matched cutting blocks for total knee arthroplasty on realiability for both clinical and radiological criteria, morbidity reduction during and after the procedure and also a benefit on an economic point of view.

OKV Versus CKC for Biomechanics and Function in Mild Knee OA Patients

OsteoarthritisKnee1 more

Background: Clinical recommendations suggest exercises as the core treatment for knee osteoarthritis (OA) patients. However, the biomechanical modification following exercise therapy and its influence on pain remains unclear. The purpose of the study to compare the effectiveness of two different exercise programs, open kinetic chain (CKC) and closed kinetic chain (CKC) strengthening exercises, on pain and lower limb biomechanics for people more than 50 years old with painful mild grade knee OA. Method: 66 individuals with mild knee OA, with knee pain in the previous one week, aged 50 years and above, and who have body mass index (BMI) between 18.9kg/m2 - 29.9 kg/m2 in Kelantan, Malaysia will be recruited in this study. Participants will be randomly allocated into three different groups, either OKC, CKC, or control groups. Participants in OKC and CKC groups will perform the exercises at their home three times per week for eight weeks. The control group will receive only the patient's clinical education about clinical manifestations, risk factors, diagnosis, treatment, and nursing care for knee OA and printed materials will be given. The outcome will be measured before and after the intervention. Primary outcomes are self-reported pain, disability, and quality of life scores. Secondary outcomes include lower limb biomechanics during gait and sit-to-stand, and knee isokinetic strength. Discussion: This study will compare the efficacy of two different home-based exercise intervention programs for people with mild grade knee OA. Findings will provide valuable information for creating an effective exercise program that could slow down the progression of OA.

Continuous Glucose Monitoring in Total Knee Arthroplasty With Preoperative High Dose Dexamethasone...

DiabetesKnee Osteoarthritis

Perioperative joint infection (PJI) is a rare but serious postoperative complication from total knee arthroplasty (TKA) and it is known to cause significant morbidities to the patients suffering from it. Literatures have found evidence that there is correlation between patients' perioperative blood glucose level and their risks of developing PJI postoperatively. By monitoring patients' perioperative blood glucose level, clinicians may be able to better identify patients who are at risks of developing PJI. Continuous blood glucose level monitoring, where patients carry a blood glucose monitoring device, has been a novel intervention in various medical specialties for recording and monitoring patients' blood glucose levels. However, currently there has only limited studies using this intervention for perioperative blood glucose monitoring in patients who are receiving total knee arthroplasty. Intravenous dexamethasone is a widely used treatment for patients undergoing total knee arthroplasty as it has been shown in previous studies that it can provide good analgesic effect and also reduce patients' nauesea symptoms preoperatively. However, hyperglycaemia is also a known side effects from dexamethasone. There still has not been ample amount of investigation on how significant this potential effect is and at what period of time perioperatively that this side effect occurs. This study is designed to investigate how intravenous dexamethasone can potentially affect the perioperative blood glucose levels in patients receiving total knee arthroplasty. And by using a continuous glucose monitoring machine we are also aiming to find out the variability of the perioperative blood glucose profiles of these patients in order to design a better glucose monitoring schedule.
