The objective of this study was to perform a systematic review and meta-analysis on the association between knee extensor muscle weakness and the risk of developing knee osteoarthritis. A systematic review and meta-analysis was conducted with literature searches in Medline, SPORTDiscus, EMBASE, CINAHL, and AMED. Eligible studies had to include participants with no radiographic or symptomatic knee osteoarthritis at baseline; have a follow-up time of a minimum of 2 years, and include a measure of knee extensor muscle strength. Hierarchies for extracting data on knee osteoarthritis and knee extensor muscle strength were defined prior to data extraction. Meta-analysis was applied on the basis of the odds ratios (ORs) of developing symptomatic knee osteoarthritis or radiographic knee osteoarthritis in subjects with knee extensor muscle weakness. ORs for knee osteoarthritis and 95% confidence intervals (CI) were estimated and combined using a random effects model. Twelve studies were eligible for inclusion in the meta-analysis after the initial searches. Five cohort studies with a follow-up time between 2.5 and 14 years, and a total number of 5707 participants (3553 males and 2154 females), were finally included. The meta-analysis showed an overall increased risk of developing symptomatic knee osteoarthritis in participants with knee extensor muscle weakness (OR 1.65 95% CI 1.23, 2.21; I(2) = 50.5%). This systematic review and meta-analysis showed that knee extensor muscle weakness was associated with an increased risk of developing knee osteoarthritis in both men and women.

“…A previous study found that lower knee extension strength and higher BMI were associated with knee pain [4]. The relationship between radiographic knee OA and quadriceps strength has also been reported [22]. In that study, the authors found that quadriceps muscle strength decreased in patients after age 50 years and a tendency for muscle strength to decrease with the progression of knee OA grade between grades 0 and 1 in both males and females.…”

Purpose: The purposes of this study were to examine population-based reference data for sex-and age-related differences between the 2011 revised Knee Society Score (KSS2011) and the Knee injury and Osteoarthritis Outcome Score (KOOS), to assess the correlation between those scores and radiographic knee osteoarthritis (OA), and to validate the use of the scores in a general Japanese population. Methods: This cross-sectional study included 963 volunteers (368 males, 595 females; mean age: 54.7 years). Participants were classified into five subgroups by age: under 40, 40s, 50s, 60s, and over 70 years old. The KSS2011 and KOOS were determined using self-administered questionnaires. Weight-bearing radiographs of the bilateral knee were taken and graded according to the Kellgren-Lawrence (KL) scale. The mean KSS2011 and KOOS were compared among age groups. Correlations between the severity of knee OA and each score were assessed using multiple regression analysis. Results: The overall KSS2011 tended to gradually decrease with age. Most subscales of the KSS2011 did not show sex-related differences. Similarly, the overall KOOS and all its subscales steadily decreased by approximately 20 points per decade with age. Most subscales of the KOOS were significantly decreased in females over 50. The KL grade was significantly related to both the overall KOOS (β = −0.42, p b 0.001) and KSS2011 (β = −0.13, p = 0.001), though the correlation to the KOOS was stronger. Conclusion: The overall KSS2011 and KOOS appear to decrease with age. In this population, the KOOS reflects the severity of knee OA better than the KSS2011.

“…Subjects of this study were the participants of the Matsudai Knee Osteoarthritis Survey 2010 [12,13]. In this survey, basic data were collected by a questionnaire, physical examination, gait analysis, quadriceps muscle strength measurement, calcaneal bone mineral density measurement, and knee radiographs.…”
