BACKGROUND: Knee osteoarthritis is a chronic degenerative disease, known as the most common cause of difficulty walking in older adults and subsequently is associated with slow walking. Functional decline, increased risk of falls and the presence of pain are, in many studies, related to the muscle weakness caused by osteoarthritis especially weakness of the quadriceps muscles. Many studies have shown that the strength of the quadriceps femoris muscle can affect gait, by improving or weakening it. Kinesio Tape is a physiotherapeutic technique, which reduces pain and increases muscular strength by irritating the skin receptors.AIM: This study aimed to verify if the application of Kinesio Tape on quadriceps femoris muscle increases gait speed while decreasing the time needed to accomplish the 10-meter walk test in patients with knee osteoarthritis and also in subjects without knee osteoarthritis.METHOD: In this study, we observed the change of gait speed with the help of the 10-meter walk test before, one day and three days after the application of Kinesio Tape in quadriceps femoris muscle. We compared the results of the time needed to perform the 10-meter walk in two groups. In the first group, the Patients group, participated 102 out-patients with a clinical diagnosis of primary knee osteoarthritis, while in the second group, the Control group, participated 73 subjects with a main excluding criterion a clinical diagnosis of primary knee osteoarthritis.RESULTS: Our results indicated that there was a significant decrease of time needed to perform the 10-meter walk test in both groups three days after application of Kinesio Tape on quadriceps femoris muscle. However, there was not a significant change one day after the application of Kinesio Tape compared before its application in both groups.CONCLUSIONS: Our results indicated that there was a significant decrease in time needed to accomplish the 10-meter walk test. Kinesio Tape is a technique that can be used especially when changing walking stereotypes is a long-term goal of the treatment.

Objectives To examine whether metabolic syndrome or its individual components predict the risk of incident knee osteoarthritis (OA) in a prospective cohort study during a 32-year follow-up period. Design The cohort consisted of 6274 participants of the Mini-Finland Health Survey, who were free from knee OA and insulin-treated diabetes at baseline. Information on the baseline characteristics, including metabolic syndrome components, hypertension, elevated fasting glucose, elevated triglycerides, reduced high-density lipoprotein, and central obesity were collected during a health examination. We drew information on the incidence of clinical knee OA from the national Care Register for Health Care. Of the participants, 459 developed incident knee OA. In our full model, age, gender, body mass index, history of physical workload, smoking history, knee complaint, and previous injury of the knee were entered as potential confounding factors. Results Having metabolic syndrome at baseline was not associated with an increased risk of incident knee OA. In the full model, the hazard ratio for incident knee OA for those with metabolic syndrome was 0.76 (95% confidence interval [0.56, 1.01]). The number of metabolic syndrome components or any individual component did not predict an increased risk of knee OA. Of the components, elevated plasma fasting glucose was associated with a reduced risk of incident knee OA (hazard ratio 0.71, 95% confidence interval [0.55, 0.91]). Conclusions Our findings do not support the hypothesis that metabolic syndrome or its components increase the risk of incident knee OA. In fact, elevated fasting glucose levels seemed to predict a reduced risk.

Abstract Background Adolescent knee pain is a common complaint which may be due to patellar dislocation, meniscal tear, Osgood-Schlatter’s disease or patellofemoral maltracking. We studied the association of such pain with knee osteoarthritis (OA) 50 years later using a retrospective cohort design. Methods This study was based in the Hertfordshire Cohort Study, a cohort of men and women born in 1931 - 9. Participants completed a questionnaire detailing recall of adolescent knee pain, self-reported OA, demographics, lifestyle and The Western Ontario and McMaster Universities Arthritis Index (WOMAC). Clinical OA was defined based on the American College of Rheumatology (ACR) criteria and assessed at a clinical visit where knee radiographs were also taken and graded according to the methods of Kellgren and Lawrence. Results Completed data were available for 135 men and 139 women. The mean age was 78.8 (SD 2.6) years and the mean (SD) BMI was 26.3 (4.0). Two percent of men (n = 3) and 5% of women (n = 7) reported adolescent knee pain, of which 2 men and 3 women sought medical advice for their knee pain. 1 man and 2 women reported that their pain had been constant since teenage years while 2 men and 4 women reported that it was intermittent in nature. A report of adolescent knee pain was associated with an increased risk of clinical (odds ratio (OR) 5.45, p-value 0.015, 95% confidence interval (CI) 1.39 - 21.36); radiological (OR 2.33, p-value 0.228, 95% CI 0.60 - 9.24) and self-report (OR 2.71, p-value 0.134, 95% CI 0.74 - 10.0) of knee OA in later life. After adjustments for age, sex and BMI, adolescent knee pain was associated with an increased risk of clinical (OR 4.80, p-value 0.047, 95% CI 1.02 - 22.53); radiological (OR 1.85, p-value 0.404, 95% CI 0.44 - 7.78); self-report (OR 3.23, p-value 0.10, 95% CI 0.80 - 12.94) although relationships were only significant for clinical knee OA. Conclusion Recalled adolescent knee pain was associated with a clinical diagnosis of knee OA in later life. The lack of association with self-report of OA suggests that this is not simply a consequence of recall bias and exploration in other data sets is now indicated. Disclosures M.A. Clynes: None. F.

Knee osteoarthritis (OA) is a serious disease and has no cure to date. Knee OA is a leading cause of functional limitation (e.g., difficulty walking). Walking speed is 1 method of quantifying difficulty with walking and should be assessed in clinical practice for adults with knee OA because it has prognostic value and is modifiable. Specifically, slow walking speed is associated with increased risk of adverse health outcomes, including all-cause mortality in adults with knee OA and can be modified by engaging in physical activity or exercise. However, at present, there is little consensus on the distance and instructions used to conduct the walk test. Distance is often selected based on space availability, and instruction varies, from asking the participants to walk at a comfortable pace versus as fast as possible. Therefore, the purpose of this narrative review is to summarize the measurement properties, strengths, and limitations of a fixed-distance walk test ≤ 40 meters in adults with knee OA. Good measurement properties in terms of reliability and validity were observed across the different testing protocols for fixed-distance walk test (i.e., any distance ≤ 40 m and fast- or self-paced). Therefore, clinicians and researchers can select a testing protocol that can safely and consistently be performed over time, as well as provide a practice trial to acclimatize the patients to the fixed-distance walk test.

Objective.To identify plasma markers associated with an increased risk of radiographic knee osteoarthritis(OA) progression using a metabolomics approach.Methods.Study participants were from the Multicenter Osteoarthritis Study (MOST) and were categorized into 2 groups based on the presence of baseline radiographic OA. Subjects in group 1 had unilateral knee OA and subjects in group 2 had bilateral knee OA. Progression was defined as a half-grade or greater worsening in joint space width at 30-month follow-up. For group 1, a participant progressed when their OA knee showed radiographic progression and the contralateral knee developed OA; for group 2, a participant progressed when both knees with OA showed radiographic progression. Metabolomic profiling was performed on plasma samples collected at baseline and logistic regression was performed to test the association between each metabolite and knee OA progression after adjustment for age, sex, BMI, and clinic site. Significance was defined as P ≤ 0.0003 in the combined analysis.Results.There were 234 progressors (57 in group 1 and 177 in group 2) and 322 nonprogressors (206 in group 1 and 116 in group 2) included in the analyses. Among 157 metabolites studied, we found that odds of progression were 1.46 times higher per SD increase of phenylalanine level (95% CI 1.20–1.77, P = 0.0001) in the combined analysis. Sex-specific analysis showed that an association was seen in women (P = 0.0002) but not in men.Conclusion.Our data suggest that phenylalanine might be a novel plasma marker for higher risk of bilateral radiographic knee OA progression in women.

Risk Factors For Falls

Objectives: Deteriorating functionality and loss of mobility, resulting from Parkinson’s disease, may be worsened by osteoarthritis, which is the most common form of joint disease causing pain and functional impairment. We assessed the association between symptomatic hip or knee osteoarthritis, falls, and the ability to walk among patients with Parkinson’s disease compared to a control group. Methods: A total of 136 patients with Parkinson’s disease in Southern Estonia and 142 controls with an average age of 76.8 and 76.3 years, respectively, were enrolled in a retrospective case-control study. Information on falls and related fractures during the previous year was collected from the patients with Parkinson’s disease and controls. Covariates included gender, age, mobility, duration of Parkinson’s disease, and fractures. Results: Patients with Parkinson’s disease were at an increased risk of falls compared to the control group, and for the higher risk of fractures. Symptomatic knee or hip osteoarthritis was a significant independent predictor of falls in both patients with Parkinson’s disease and controls. The higher risk for fractures during the previous year was demonstrated in symptomatic osteoarthritis. Risk factors for falls included also female gender, use of sleep pills, and the inability to walk 500 m. Conclusions: Symptomatic hip and knee osteoarthritis are risk factors for falls and related fractures among the elderly population with and without Parkinson’s disease. The inability to walk 500 m could be used as a simple predictive factor for the increased risk of falls among elderly populations.

This study investigates the effects of early fitting in trans-tibial amputees. The assumption is that compared to elastic bandaging, the use of a rigid dressing in early fitting will result in quicker wound healing and earlier ambulation. A retrospective file search was carried out in three different hospitals, analysing the time to first prosthesis, the incidence of local and general complications and the functional outcome after discharge from hospital. Each of the hospitals used a different method of postoperative care: elastic bandaging, immediate postoperative application of the plaster cast or delayed application of the plaster cast within one week post amputation. In comparison to the elastic bandaging method (N=52), the use of a rigid dressing in the early fitting method (immediate and delayed, N=97) resulted in a statistically significant shorter period from amputation to the delivery of a first regular prosthesis (110 days vs 50 days) and a decreased risk of knee flexion contracture. Although, differences in local complications were not observed, the risk of pressure sores in other places than the stump was increased in early fitting. Instead of further reducing the time to first prosthesis by immediate fitting, the use of delayed fitting resulted in a statistically significant shorter period from amputation to the delivery of a first regular prosthesis (56 vs 40 days). However, delayed fitting was associated with an increased risk for reamputation. In conclusion, this study indicates that early fitting by use of a rigid dressing after trans-tibial amputation is the treatment of choice. If it is possible to apply a plaster cast in the operating room, the authors would prefer the immediate fitting method.

Background: Female athletes have a higher rate of anterior cruciate ligament (ACL) injury than males from adolescence and into maturity, which is suggested to result from sex-specific changes in dynamic movement patterns with maturation. Few studies have studied movement strategies and response to fatigue in children. Purpose: To evaluate the effect of fatigue on biomechanical variables associated with increased risk for ACL injury during a drop-jump (DJ) performance in children. Study Design: Controlled laboratory study. Methods: A total of 116 children (mean age, 10.4 years) were recruited from local sports clubs and performed 5 repetitions of a DJ task before and after a fatigue protocol. Kinematic and kinetic data from initial contact (IC) to the first peak vertical ground reaction force (vGRF) were analyzed for both limbs, including limb and fatigue as within-subject factors for analyses between boys and girls. Pearson correlation coefficients were calculated to identify associations between variables of interest. Results: Girls demonstrated greater peak vGRF values than boys (by 8.1%; P < .05), there were greater peak vGRF values for the right limb than the left (by 6.2%; P < .001), and fatigue led to slightly greater values ( P < .05). Although weak, the correlation between peak vGRF values and knee flexion excursion was stronger for girls ( r = –0.20) than boys ( r = –0.08) ( P < .006). Fatigue resulted in greater knee flexion angles at IC and less excursion during landing, more so for girls (by 6.1° vs 1.4°; interaction, P < .001), although the knee flexion moment was generally lowered by fatigue ( P < .001). Limb asymmetry in knee flexion moments was more pronounced for boys than for girls (interaction, P < .05), contrary to that seen in frontal plane knee moments, where asymmetry was much greater in girls than boys (interaction, P < .001). Conclusion: Even as young athletes, girls and boys seem to adopt dissimilar movement strategies and are differently affected by fatigue. Clinical Relevance: Injury prevention programs should be considered at an earlier age in an effort to lower the risk of ACL injury in athletes.
