Brief Summary
The goal of this observational study is to compare the functional outcome of patients with end-stage knee osteoarthritis (OA) before and after total knee arthroplasty based on the phase angle level. The main questions it aims to answer are:
- Do patients with low phase angle show worse functional recovery after total knee arthroplasty compared to those with high phase angle?
- Is postoperative physical function associated with preoperative phase angle level? Researchers will compare postoperative physical function and muscle strength between the low and high phase angle groups to determine whether a low phase angle is associated with poorer functional recovery. Participants will: Perform physical function tests, isokinetic strength assessments, and bioelectrical impedance analysis before and three months after surgery.

Outcome Measures
Primary Outcomes (3)
Timed up and go test (TUG)
Researchers ask patients to rise from a seated position, walk a distance of 3 m, turn around, return to the chair, and sit back. The average time of three trials was recorded as a result
Baseline and 3 months after surgery
10 meter walk test (10MWT)
Patients are instructed to walk 14 m, including 2 m at both ends for acceleration and deceleration, at their comfortable speed. Gait speed was calculated by dividing the 10m distance by the time taken.
Baseline and 3 months after surgery
Berg balance scale (BBS)
Patients are asked to perform 14 tasks regarding the static and dynamic balance of patients. Each task was rated on a five-point scale from 0 to 4, with a total score of 56.
Baseline and 3 months after surgery
Secondary Outcomes (9)
Isokinetic peak torque of knee flexion at 60°/s
Baseline and 3 months after surgery
Isokinetic peak torque of knee flexion at 150°/s
Baseline and 3 months after surgery
Isokinetic peak torque of knee extension at 60°/s
Baseline and 3 months after surgery
Isokinetic peak torque of knee extension at 150°/s
Baseline and 3 months after surgery
Isokinetic total work of knee flexion at 60°/s
Baseline and 3 months after surgery
- +4 more secondary outcomes
Study Arms (2)
high PhA
* Patients diagnosed with knee osteoarthritis and scheduled for total knee arthroplasty. * Among these, patients are classified into the high PhA group if their preoperative PhA is above 4.95 for males or 4.35 for females
low PhA
* Patients diagnosed with knee osteoarthritis and scheduled for total knee arthroplasty. * Among these, patients are classified into the low PhA group if their preoperative PhA is below 4.95 for males or 4.35 for females
Eligibility Criteria
Single general hospital
You may qualify if:
- Individuals aged 55 and over (based on the age on their national ID at the time of consent)
- Individuals diagnosed with knee OA based on medical history, physical examination, and radiographic assessments.
- Individuals who plan to perform total knee arthroplasty
You may not qualify if:
- Individuals with gait disturbance due to neurologic disorders such as Parkinson disease, stroke and dementia
- Individuals with severe cardiac, pulmonary, or musculoskeletal disorders that limited quadriceps strength and physical function
- Individuals with knee osteoarthritis due to secondary causes such as rheumatic or traumatic arthritis
- Individuals with a history of any knee surgery within one year.
- Individuals considered clinically unsuitable for the study by the researchers or person in charge based on significant medical findings.
