This study is a prospective multicentre randomised clinical trial to be conducted in orthopaedic departments of two Slovenian hospitals. In each hospital 125 patients aged 60 or older with unilateral osteoarthritis, ASA score 1-3, signed informed consent, access to watching USB videos and without terminal illnesses disabling rehabilitation participation, will be randomly assigned to intervention (IG) or control group (CG). Total hip arthroplasty with anterior approach will be performed. All patients will get current standard physiotherapy during hospitalisation. Patients in IG will additionally learn strength and sensory-motor training exercises. Patients in both groups will get USB drives with exercise videos, written exercise instructions and training diary. Physiotherapists will perform measurements (physical tests and maximal voluntary isometric contractions) and patients will fill in outcome assessment questionnaires (Harris Hip Score and 36-Item Short Form Health Survey) at baseline and 1, 3 and 12 months after surgery.
