Objective: To investigate the effects of core stability exercises (CSE) added to the standard exercises (SE) on patient-reported (PR) and performance-based (PB) outcomes in patients with total knee arthroplasty (TKA) followed with telerehabilitation (TR). Methods: The 42 patients who participated in the study were randomly divided into 2 groups \[group 1: SE (n= 21), group 2: SE + CSE (n= 21)\]. The first 8 weeks of the post-discharge follow-up were performed by videoconference-based TR under the supervision of a physiotherapist and the last 4 weeks by telephone-based TR. Functional level was assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), pain intensity by Visual Analog Scale (VAS), affected knee range of motion (ROM) by Copenhagen Knee Range of Motion Scale (CKRS), quality of life by Short Form-12 (SF-12) and World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF), lower extremity muscle strength by 30-seconds Chair-Stand Test and locomotor performance by Stair Climb Test. Assessments were performed with TR preoperatively and at the first, second and third post-op months.
