Osteoarthritis year in review 2021: mechanics

“…After ACL reconstruction, participants spent 17% less time walking, especially at a moderate-to vigorous-intensity. Using a thigh-worn accelerometer, activities of women with knee OA did not differ from their non-OA peers 66 . To feedback cumulative joint load based on activity classification, a smartphone app was cocreated with OA patients and healthcare providers 67 .…”

Real-world gait and turning in individuals scheduled for total knee arthroplasty

“…lower back vs. feet), definitions of gait bout start and stops, and degrees of freedom in heading direction -may have had a substantial impact on the derived gait and turning performance parameters. Although such influences on the between-group comparisons in our study are likely small, they limit comparison of results with other studies that used different sensor configurations and/or algorithms (13,20,(28)(29)(30). Secondly, battery life of the sensors was limited to 10-12 hours.…”

“…Inertial measurement units (IMUs) have facilitated research into real-world mobility, enabling unobtrusive and continuous recording of gait and turning performance. In contrast to elderly and neurological populations (13,(19)(20)(21)(22)(23)(24)(25)(26), studies evaluating real-world gait and turning in individuals with knee OA are scarce (27)(28)(29). Of these studies, only Chapman et al (27) compared individuals scheduled for TKA with a healthy control group.…”

A Review of the Relationships Between Knee Pain and Movement Neuromechanics

“…Premature degeneration of articular cartilage is known to occur simultaneous to abnormal joint biomechanics in multiple aberrant health conditions including PFP, 89 ACLR, [90][91][92][93] and obesity. [94][95][96] Joint degeneration is associated with biomechanics reflecting joint overloading and underloading for ACLR and obesity. [90][91][92][94][95][96] The idea that abnormal loads contribute to premature articular cartilage degradation is a difficult idea to test using human subjects and will likely require future longitudinal research.…”

Such longitudinal data will be essential to understanding ramifications of joint pain.…”
