Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Patients and Methods: In total, 29 unilateral TKA candidates (58 knees; mean age = 66.69 ± 7.42 years; mean symptom duration = 10 ± 5.40 years) were enrolled. The knees of patients with bilateral advanced knee osteoarthritis (stage 3 or 4), according to the Kellgren-Lawrence (K-L scale), that were scheduled for unilateral TKA were divided into surgical and non-surgical groups. An isokinetic testing system was used to assess knee flexor and extensor muscle strength (peak torque) at angular velocities of 60°/s and 180°/s (five cycles per velocity). The radiological (X-ray-based K-L scale and magnetic resonance imaging (MRI)-based quadriceps angle) and clinical findings (isokinetic test and visual analog scale pain scores) in both groups were compared. The isokinetic test results correlated with the radiological findings of the surgery group.

surgical knee group
This study analyzed 58 knees of 29 unilateral TKA candidates, divided into the surgical and non-surgical knee groups
isokinetic testing CSMI HUMAC NORM instrument
The strength (PT) of the bilateral knee flexors and extensors were tested with isokinetic test. Tests were performed under the guidance of a rehabilitation medicine specialist, and the system was calibrated prior to their commencement. The patients were seated in upright position and were fixed with pelvic and thigh belts. Concentric extension (PT\_E) and concentric flexion (PT\_F) were measured between the 0° and 90° knee ranges at angular velocities of 60°/s and 180°/s (60 PT\_E, 60 PT\_F, 180 PT\_E, and 180 PT\_F, respectively) The tests were repeated five times at each velocity, and the highest PTs were selected for statistical analysis. The participants performed repeated trials before sets, while a 20-second rest was provided between sets.
