“…Knee joint mechanoreceptors and knee muscle spindles both have major roles in joint position and movement perception [27,28]. Knee joint mechanoreceptors are at the primary site of pathology in knee OA and muscle spindles are also known to be altered by knee OA [29,30]. Differences in proprioceptive accuracy as tested with repositioning tests may be explained by differences in the damage to the joint and consequently to the joint mechanoreceptors, which is more severe in established OA compared to the early group.…”

“…In several studies, sarcopenia (a reduction in the number and size of muscle fibers with specific atrophy of Type II fibers) in those approaching their sixth decade of life was observed [8,10,21]. It therefore is possible age-related muscle atrophy can result in a normal, physiologic proximal retraction of the cusp of the biceps muscle belly.…”

Complete distal biceps tendon ruptures require prompt surgical management for optimal functional and aesthetic outcome. The need exists for a valid and reliable diagnostic tool to expedite surgical referral. We hypothesized complete distal biceps tendon ruptures result in an objectively measurable anatomic landmark (the distance between the antecubital crease of the elbow and the cusp of distal descent of the biceps muscle, or the biceps crease interval), as a result of proximal retraction of the musculotendinous complex. We established normal biceps crease interval values and biceps crease ratios between dominant and nondominant arms in 80 men with no history of biceps injury (average age, 43 years). The mean (± standard deviation) biceps crease interval for dominant and nondominant arms was 4.8 ± 0.6 cm. The mean biceps crease ratio was 1.0 ± 0.1. We measured the biceps crease interval and biceps crease ratio on 29 consecutive patients presenting with a possible complete distal biceps tendon rupture. Using a diagnostic threshold of a biceps crease interval greater than 6.0 cm or biceps crease ratio greater than 1.2, the biceps crease interval test had a sensitivity of 96% and a diagnostic accuracy of 93% for identifying complete distal biceps tendon ruptures, making it a valid and reliable tool for clinicians to identify cases requiring urgent surgical referral.

“…Previous studies reported a reduction in strength (5,16,17) and muscle quality (strength per muscle area unit) (18) in subjects with radiographic KOA, but it is controversial, i.e., whether muscle strength is directly associated with structural (radiographic) knee status, or whether the association is indirect, given the associations between radiographic change and knee pain (15).…”

“…Previous studies on the association between muscle strength, pain, and radiographic change did not include the whole spectrum of radiographic status (from "no" to "severe" OA) (5,8,16,18,19) and did not fully dissect pain and radiographic strata in their analysis (7). For instance, Berger et al (7) reported a stronger correlation between isometric quadriceps muscle strength and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores than with radiographic Kellgren/ Lawrence (K/L) grade status.…”

Objective. To determine whether thigh muscle strength differs between symptomatic and asymptomatic knees, and/or different radiographic strata of knee osteoarthritis (KOA). Results. Isometric strength was significantly lower in symptomatic than in asymptomatic legs: ؊11 to ؊13% for extensor strength and ؊7 to ؊16% for flexor strength (P < 0.0001 for both) in men, and ؊9 to ؊17% (P ‫؍‬ 0.029) for extensor strength, and ؊10 to ؊21% (P ‫؍‬ 0.049) for flexor strength in women. Similar observations were made for pain frequency strata. Extensor and flexor strength were not significantly different across K/L grade strata in asymptomatic legs in either sex (P > 0.12). However, strength normalized to body weight was lower at higher K/L grades in both sexes (P < 0.02) because the body mass index was greater in participants with more advanced radiographic disease. Conclusion. Knee symptoms (i.e., pain) appear to be the relevant determinant of isometric knee extensor and flexor strength in KOA, whereas no direct association between strength and radiographic severity was observed. These findings suggest that the reduction in thigh muscle strength in KOA is related to pain but not to the structural (radiographic) disease status.
