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.
Who can take part
Inclusion criteria
- Individuals aged 55 and over (based on the age on their national ID at the time of consent)

Exclusion criteria
- 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.
