Early clinical outcomes of total hip arthroplasty with minimally invasive direct anterior approach and traditional posterolateral approache for femoral head avascular necrosis
Objective To compare the early clinical efficacy of total hip arthroplasty with minimally invasive direct ante-rior approach and traditional lateral approach for the treatment of avascular necrosis of the femoral head.Methods A retrospective study was conducted at Baoshun Hospital of Qinzhou from January 2020 to December 2021,involving 60 pa-tients with avascular necrosis of the femoral head.Among them,30 patients underwent total hip arthroplasty using the minimally invasive direct anterior approach,while the remaining 30 patients underwent the traditional lateral approach.The data of the two groups were collected to compare various factors,including operation time,bleeding volume,hospital-ization time,Harris score of the hip joint,patient satisfaction,and postoperative complications.Results The average follow-up period for the 60 patients was 12 months.Statistically significant differences were observed between the two groups in terms of mean intraoperative blood loss[(200.8±5.6)mL vs.(401.2±10.4)mL],length of hospital stay[(6.5±1.l)d vs.(10.6±1.2)d],and Harris score[(90.0±3.3)points vs.(84.4±2.8)points]at 1 month post-operation(P<0.05).At the 6 month follow-up,the overall satisfaction level in group A was higher than that in group B[(98.5±1.3)%vs.(95.2±1.9)%,P<0.01]and the scar scale score in group A was lower than that in group B[(1.5±0.8)points vs.(3.2±1.0)points,P<0.01].Conclusion Both the minimally invasive direct anterior ap-proach and the posterolateral approach have demonstrated efficacy in treating avascular necrosis of femoral head.Howev-er,the minimally invasive direct anterior approach offers distinct advantages,including significantly reduced postoperative pain,decreased intraoperative bleeding,shorter hospital stays,and higher patients satisfaction levels.
