ABSTRACT

Objective To evaluate the quality of life of patients with Kaschin-Beck disease (KBD)receiving total knee arthroplasty (TKA) before and after the operation.Methods Clinical efficacy of 25 patients with KBD who underwent TKA in Department of Orthopaedics,Shaanxi Provincial People's Hospital from January 2015 to January 2017 was prospectively analyzed.A questionnaire survey on KBD quality of life (KBDQOL)was carried out to evaluate the quality of life of the patients before,6 months and 1 year after the surgery.Results The scores of physical function,activity limit,social support,mental status and total health scores of KBDQOL in 6 months after the surgery (30.60 ± 3.73,23.24 ± 2.03,15.16 ± 1.62,18.92 ± 2.89,12.80 ± 2.57) and 1 year after the surgery (32.00 ± 3.19,23.76 ± 1.59,15.60 ± 1.29,20.16 ± 2.67,17.28 ± 3.88) were significantly higher than those of before the surgery (18.84 ± 4.94,21.04 ± 2.72,12.80 ± 2.06,13.68 ± 3.42,7.92 ± 1.93,P ＜ 0.05).However,there was no significant difference in economic scores before,6 months and 1 year after the surgery (10.68 ± 2.98,10.60 ± 2.78,10.48 ± 2.80,P ＞ 0.05).Conclusions The quality of life after TKA in patients with KBD severe knee osteoarthritis is significantly better than that before the surgery.The KBDQOL questionnaire is an appropriate tool for evaluating the quality of life in KBD patients.
