Outcomes of total knee arthroplasty in the adult Kashin-Beck disease with severe osteoarthritis

Kashin-Beck disease (KBD) is an endemic osteoarthropathy, and the severe knee pain and functional limitations were seriously affecting the quality of life in patients with end-stage KBD. We retrospectively evaluated the clinical outcomes and the quality of life in KBD patients with total knee arthroplasty (TKA).
A total of 22 subjects (25 knees) suffered KBD with severe knee pain and underwent primary TKA. Knee pain was measured by visual analogue scale (VAS), and the knee function was evaluated by Knee Society Clinical Rating System Score (KSS). KBD Quality of Life (KBDQOL) was used to evaluate the quality of life in KBD patients before and after TKA.
There were no major complications after TKA. The levels of VAS score were obviously deceased in post-operation than that in pre-operation. The levels of KSS score were increased in one year after TKA compared with the pre-operative values, and it maintained a higher level on three years after TKA. The average KBDQOL score level of each domain in pre-operation and one and three years after TKA was increased accordingly. The average scores of physical function, activity limitation, support of society, mental health, and general health in one year after TKA were significantly higher than those in pre-operation.
TKA can reduce knee pain, improve knee function, and improve the quality life in KBD patients. KBDQOL questionnaire may be a promising instrument for assessing the quality life in KBD patients.
