Abstract:
BACKGROUND:Bone cement has certain toxic effects on the human body. The probability of renovation is high after bone cement total hip arthroplasty. It is reported that the long-term effect of cementless total hip arthroplasty is apparently better than bone cement total hip arthroplasty, and can be renovated conveniently. OBJECTIVE:To investigate the clinical effect of cementless total hip arthroplasty on hip joint disease, and to compare the difference between unilateral replacement and bilateral replacement. METHODS: Clinical and folow-up data of 233 patients (280 hips), who were treated with cementless total hip arthroplasty in the Department of Orthopedics, Wuzhou Worker’s Hospital, Seventh Affiliated Hospital of Guangxi Medical University from July 2007 to December 2013, were retrospectively analyzed. According to the replacement program, they were divided into unilateral replacement group (n=186) and bilateral replacement group (n=47). Harris score of hip joint, visual analog scale score of thigh pain, the excelent and good rate of hip joint during final folow-up and complications were compared between the two groups before replacement, at 6, 12 and 24 months after replacement. RESULTS AND CONCLUSION:No significant difference in Harris scores was detected before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Harris score was significantly higher at 6, 12 and 24 months after replacement compared with that before replacement in both groups (P < 0.05). No significant difference in the excelent and good rate was detected in the unilateral replacement group (87%) and the bilateral replacement group (86%) (P > 0.05). No significant difference in the visual analog scale score was seen before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Visual analog scale scores were significantly lower at 6, 12 and 24 months after replacement than that before replacement in the two groups (P < 0.05). There was no significant difference in the incidence of complications after replacement in patients of both groups (P > 0.05). These findings confirm that the effects of cementless total hip arthroplasty for hip joint disease are evident, can effectively restore hip joint function. No significant difference was detected between unilateral replacement and bilateral replacement. Strict replacement operation and matching of prosthesis and medulary cavity can effectively reduce thigh pain after replacement.
