Quantitative Assessment of Knee Pain and Proprioception in Tibial Rotation in Individuals With Knee Osteoarthritis.

ABSTRACT: Patients with knee osteoarthritis (OA) exhibit reduced tibial rotations, possibly as a compensatory adaptation to mitigate mechanical stimuli on surrounding tissues. Hence, the passive threshold angle at which knee pain is sensed may reflect that surrounding tissues have received mechanical stimuli sufficient to exceed the nociceptive threshold. This study aimed to measure knee pain and proprioception during tibial rotation quantitatively. Twelve patients with symptomatic medial knee OA and 12 age- and sex-matched controls were included. For patients with knee OA, knee pain was quantified using the pain threshold angle (PTA), at which pain was first perceived during robot-controlled tibial internal rotation (IR) and external rotation (ER) at 0.5°/sec.
