Abstract
BackgroundOxidative stress is a disruption of the pro-oxidative-antioxidant balance, caused by excessive production or ineffective removal of reactive oxygen species.Material/MethodsThe study included 42 male patients aged 38 to 69 years. The first group consisted of 21 men with osteoarthritis after primary hip arthroplasty using the Smith & Nephew Birmingham Hip Resurfacing implant. The second group included 21 men after hip arthroplasty using the femoral neck SPIRON K-implant. In both groups, concentrations of ions, the antioxidant system in the blood, and parameters of oxidative stress were evaluated twice. Clinical assessment using the Western Ontario and McMaster Universities Osteoarthritis Index, Harris Hip Score, and Short Form (12) Health Survey (SF-12) scales was performed.ResultsConcentrations of metal ions in the blood and the level of oxidative stress were significantly higher in the resurfacing group than in the femoral neck arthroplasty group. The response of the antioxidant system was significantly greater in the femoral neck arthroplasty group. During clinical evaluation, groups did not show significant differences, with the exception of greater shortening of the operated limb and a lower score in the mental-sphere of the SF-12 scale in the resurfacing arthroplasty group.ConclusionsResurfacing hip arthroplasty increased oxidative stress, increased the concentration of metal ions, and did not affect alignment of the abbreviation of the operated limb. A significant improvement in the quality of life of patients in the mental sphere according to the SF-12 occurred after the application of resurfacing arthroplasty, in the first month after the procedure.
