Objective: To assess the impact of total hip arthroplasty (THA) on functional outcomes and fall risk in patients with hip osteoarthritis. The objective was to investigate the effectiveness of physical therapy in postoperative rehabilitation and identify fall risk factors to guide fall prevention strategies after THA. Methods: A non-randomized, interventional clinical trial was conducted with 30 patients scheduled for THA. Functional outcomes were evaluated using the Harris Hip Score (HHS), 40-meter fast-paced walk test (40mFPWT), 30-Second Chair Test, and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Balance and fall risk were assessed using the Single-Leg Standing Test and a posturography device (TETRAX). The Nottingham Health Profile (NHP) was used to measure subjective health status and quality of life. Assessments were performed preoperatively, at 6 weeks postoperatively, and at 3 months postoperatively.

30 patients took postoperative rehabilitation after total hip arthroplasty surgery, 3 times a week, for 6 weeks. They took conventional rehabilitation (hip range of motion exercises, progressive strengthening exercises for hip and knee muscles, balance and proprioceptive exercises and gait training).
Harris Hip Score (HHS)
min-max (0-100) Results can be interpreted with the following: \<70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent.
Time frame: preoperative, postoperative 6 weeks and 3 months
40-meter fast-paced walk test
Time frame: preoperative, postoperative 6 weeks and 3 months
30-Second Chair Test
Time frame: preoperative, postoperative 6 weeks and 3 months
Western Ontario McMaster Universities Osteoarthritis Index (WOMAC)
It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: Pain, Stiffness, Physical Function. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.
Time frame: preoperative, postoperative 6 weeks and 3 months
Static balance and fall risk
It was assessed with Posturography device (TETRAX)
Time frame: preoperative, postoperative 6 weeks and 3 months
Single-Leg Standing Test
Time frame: preoperative, postoperative 6 weeks and 3 months
The Nottingham Health Profile (NHP)
The NHP is composed of 38 items divided into six domains: 1. Sleep 2. Mobility 3. Energy 4. Pain 5. Emotional reactions 6. Social isolation Items use a Yes/No answer format. Each item is weighted. NHP scores are calculated by averaging domain scores. Total scores range from 0 (no perceived distress) to 100 (maximum perceived distress).
Time frame: preoperative, postoperative 6 weeks and 3 months
