Objectives: This study analyzed whether the isokinetic muscle strength of bilateral knee osteoarthritis patients undergoing unilateral total knee arthroplasty (TKA) is a predictor for prior surgery side. Patients and methods: In the prospective study conducted between April 2021 and December 2021, 58 knees of 29 unilateral TKA candidates (6 males, 23 females; mean age: 66.7±7.4 years; range, 53 to 81 years) were enrolled. The patients were divided into surgical (n=29)and nonsurgical (n=29) groups. The knees of patients with bilateral knee osteoarthritis (Stage III or IV) according to the Kellgren-Lawrence (KL) scale were scheduled for unilateral TKA. An isokinetic testing system was used to assess knee flexor and extensor muscle strength (peak torque) at angular velocities of 60°/sec and 180°/sec (five cycles per velocity). The radiological (X-ray-based KL scale and magnetic resonance imaging-based quadriceps angle) and clinical findings (isokinetic test and Visual Analog Scale pain scores) in both groups were compared. Results: The mean symptom duration was 10±5.4 years. The KL score and quadriceps angle showed no significant differences (p=0.056 and p=0.663, respectively). Isokinetic test results were in accordance with the clinical results of the surgery group. In the isokinetic evaluation, both the 60°/sec concentric extension (35.00 vs. 46.00, p=0.002) and flexion peak torque (18.00 vs. 26.00, p=0.001) values were significantly lower in the surgical group than in the nonsurgical group. Conclusion: Isokinetic testing can be a supportive tool for assessing the prior side of TKA in patients with bilateral knee osteoarthritis. Further studies are required to support these findings.

Aim: Baseline evaluation of stroke patients is valuable to manage the treatment plan. As in the case of stroke evaluation and rehabilitation, in every aspects of healthcare, tele-medicine is growing gradually. The aim of this descriptive study was to explore whether initial tele-assessment of chronic stroke patients is similar to face-to-face assessment in terms of clinical scales. Material and Method: Thirty-four chronic stroke patients (mean post-stroke duration 21.44±15.47 months; stroke etiology, 58.8% ischemic; hemiplegic side, 52.9% left; mean age 49.24±12.51; 22 males; 12 females) were included in this trial. Firstly, all the patients were evaluated online, and then at the same day they were evaluated face-to-face by the clinical scales including Chair Stand Test, Berg Balance Scale, Stroke specific Quality of Life scale, Motricity Index. Results: The findings of the present study revealed that there was no statistically significant difference between tele-assessment and face-to-face assessment for all the scales (p>0.05) except Chair Stand Test (mean time to stand: 9.41 secs vs 8.94 secs in tele-assessment and face-to-face respectively; p
