Comparison of Functional Recovery After Total Knee Arthroplasty Between Low Phase Angle and High Phase Angle Group

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.

Eligibility

Inclusion Criteria:

* 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

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.
