Abstract Background Osteoarthritis (OA) is a chronic and painful condition where the articular cartilage surfaces progressively degenerate, resulting in loss of function and progressive disability. Obesity is a primary risk factor for the development and progression of knee OA, defined as the “metabolic OA” phenotype. Metabolic OA is associated with increased fat deposits that release inflammatory cytokines/adipokines, thereby resulting in systemic inflammation which can contribute to cartilage degeneration. There is currently no cure for OA. Prebiotics are a type of dietary fiber that can positively influence gut microbiota thereby reducing systemic inflammation and offering protection of joint integrity in rodents. However, no human clinical trials have tested the effects of prebiotics in adults with obesity suffering from knee OA. Therefore, the purpose of this double-blind, placebo-controlled, randomized trial is to determine if prebiotic supplementation can, through positive changes in the gut microbiota, improve knee function and physical performance in adults with obesity and knee OA. Methods Adults (n = 60) with co-morbid obesity (BMI > 30 kg/m2) and knee OA (Kellgren-Lawrence grade II–III) will be recruited from the Alberta Hip and Knee Clinic and the Rocky Mountain Health Clinic and surrounding community of Calgary, Canada, and randomized (stratified by sex, BMI, and age) to prebiotic (oligofructose-enriched inulin; 16 g/day) or a calorie-matched placebo (maltodextrin) for 6 months. Anthropometrics, performance-based tests, knee pain, serum inflammatory markers and metabolomics, quality of life, and gut microbiota will be assessed at baseline, 3 months, 6 months (end of prebiotic supplementation), and 3 months following the end of the prebiotic supplementation. Clinical significance There is growing pressure on health care systems for aggressive OA treatment such as total joint replacement. Less aggressive, yet effective, conservative treatment options have the potential to address the growing prevalence of co-morbid obesity and knee OA by delaying the need for joint replacement or ideally preventing its need altogether. The results of this clinical trial will provide the first evidence regarding the efficacy of prebiotic supplementation on knee joint function and pain in adults with obesity and knee OA. If successful, the results may provide a simple, safe, and easy to adhere to intervention to reduce knee joint pain and improve the quality of life of adults with co-morbid knee OA and obesity.

Knee surgeries are the most commonly performed joint surgeries in the modern world, which help maintain the quality of life by improving joint functions. These include open trauma, sports injury, or joint replacement surgeries. Among various available regional analgesia options for knee surgeries, the goal is to choose motor-sparing, opioid-sparing, and procedure-specific modalities. Therefore, it is essential to know the complex anatomy of the knee joint, essential steps of various surgical procedures, and innervations of the pain-generating structures for a particular surgery. Background knowledge of all these essentials helps select the most appropriate regional analgesia technique for knee surgeries.

Introduction: Osteoarthritis (OA) is the most common and burdensome illness in the elderly patients. It is the main cause of locomotor impairment and disability resulting in significant decrease of the quality of life (QL) in highly developed countries. Sf-36v2 questionnaire was standardized in the United States by J.E. Ware et al. in the years 1985-1992 and at present SF-36v2 is the most commonly used questionnaire for investigations in patients with various conditions. The aim: To compare two cohorts of post-menopausal female patients with the predominantly clinically active one-site advanced osteoarthritis of the hip and knee joint prior to the replacement surgery. Material and methods: Two cohorts of fifty female postmenopausal patients aged from sixty to eighty were investigated. The inclusion criteria relied on sex, age and clinically single joint predominant OA disease prior to hip and knee joint replacement. The Polish version of SF-36v2 for the quality of life was accomplished by the patient under direct supervision of a trained nurse. The sets of obtained data were analyzed with the use of Statistica 10.0 (Shapiro-Wilk test, U - Mann-Whitney test, Spearmann, Kruskall-Wallis, Friedmann’s ANOVA and Chi 2 Pearson). P<0.05 was regarded as significant. Results: It was found that patients with advanced knee OA demonstrated significantly lower QL than these with hip OA in Vitality (p=0,004), Functioning in Social Roles (p=0,0001), General Health (p<0,000001) and Pain (p<0,000001). No significant differences within the cohorts were observed as the other scales were concerned (p>0,05). In the general assessment as for the QL in the Physical domain significant difference was found with lower scoring in the knee group (p=0.00001). In the assessment of the general QL two domains were considered -Physical and Mental Health. Highly significant difference was recorded for the Physical better in regard for hip OA (p<0,00001). In the Mental Health domain no significant difference was found (p=0,09). Conclusions: 1. Quality of life of postmenopausal women with hip OA is predominantly lowered by the local disease whereas lower quality of life of these females with knee OA is related to the general poor health, low index of vitality and decrease of function in social functioning resulting from co-existence of chronic illnesses due to overweight and obesity. 2. Reduction of overweight or obesity in the group of patients with knee arthritis could improve their quality of life and general health.

Knee osteoarthritis (KOA) is a degenerative joint disease characterized by articular cartilage degeneration, cartilage exfoliation, osteophyte formation, and synovitis. It seriously affects the knee joint function and quality of life of patients. Total knee arthroplasty is now the most frequently used therapy for end-stage knee arthritis because it can successfully modify the line of lower extremities, restore knee joint function, alleviate pain, and enhance patients’ quality of life; nevertheless, it may cause significant trauma and bleeding. It can easily lead to infection and anemia. In this study, the control group chose total knee arthroplasty and the observation group chose total knee arthroplasty combined with PRP. The results showed that the knee joint function score, visual analog score, blood transfusion, total blood loss, total postoperative drainage, and complications in the observation group were superior to those in the control group. Total knee arthroplasty takes a long time and needs a lot of soft tissue incision, which leads to a lot of blood loss and can cause a variety of complications. Gel has been shown in studies to successfully decrease blood loss during and after total knee arthroplasty, enhance knee joint function recovery, and improve patient quality of life. In this paper, the complications and causes of knee osteoarthritis after total knee arthroplasty were studied. Combined with comprehensive nursing intervention for postoperative recovery, it helps to improve the formation of thrombin and calcium ion, which can effectively reduce blood loss, relieve pain, and promote the recovery of knee joint function. This study analyzed the application of total knee arthroplasty combined with gel in the treatment of knee osteoarthritis.

The Impact

Aims The aim of this study was to evaluate health-related quality of life (HRQoL) and joint function in tenosynovial giant cell tumour (TGCT) patients before and after surgical treatment. Patients and Methods This prospective cohort study run in two Dutch referral centres assessed patient-reported outcome measures (PROMs; 36-Item Short-Form Health Survey (SF-36), visual analogue scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) in 359 consecutive patients with localized- and diffuse-type TGCT of large joints. Patients with recurrent disease (n = 121) and a wait-and-see policy (n = 32) were excluded. Collected data were analyzed at specified time intervals preoperatively (baseline) and/or postoperatively up to five years. Results A total of 206 TGCT patients, 108 localized- and 98 diffuse-type, were analyzed. Median age at diagnosis of localized- and diffuse-type was 41 years (interquartile range (IQR) 29 to 49) and 37 years (IQR 27 to 47), respectively. SF-36 analyses showed statistically significant and clinically relevant deteriorated preoperative and immediate postoperative scores compared with general Dutch population means, depending on subscale and TGCT subtype. After three to six months of follow-up, these scores improved to general population means and continued to be fairly stable over the following years. VAS scores, for both subtypes, showed no statistically significant or clinically relevant differences pre- or postoperatively. In diffuse-type patients, the improvement in median WOMAC score was statistically significant and clinically relevant preoperatively versus six to 24 months postoperatively, and remained up to five years’ follow-up. Conclusion Patients with TGCT report a better HRQoL and joint function after surgery. Pain scores, which vary hugely between patients and in patients over time, did not improve. A disease-specific PROM would help to decipher the impact of TGCT on patients’ daily life and functioning in more detail. Cite this article: Bone Joint J 2019;101-B:272–280.
