Background:
Total knee arthroplasty (TKA) is an important treatment for knee osteoarthritis, but the result of whole-body vibration (WBV) in knee function rehabilitation and bone loss with osteopenia was unknown. Therefore, the purpose of this study is to study whether low-frequency, low-amplitude WBV can improve the clinical outcome of knee osteoarthritis.
Methods:
This study was randomized and included 67 osteopenic patients (55-90 years, 85% women) for TKA surgery (control group N = 32, WBV group N = 35). All selected patients after TKA surgery tested clinical results, such as knee function and bone mass in baseline, 3 months after surgery, and 6 months after surgery.
Results:
Compared to the control group, the WBV group improved pain scores, thigh circumference, lower limb muscle strength, joint activity, and joint function in 6 months after surgery. WBV intervention also improves bone density in the spine, the microstructure of the radius and tibia, and the bone turnover marker. At 3 months after TKA surgery, the WBV group had no significant effect on knee function and bone loss.
Conclusions:
Whole-body vibration for osteopenic patients with knee arthroplasty showed good therapeutic results in 6 months after TKA surgery, but the long-term therapeutic effect still needs to be further observed.
