Aims: Restoration of normal hip biomechanics in arthroplasty surgery is important in order to achieve good muscle function and joint stability. Methods: In this retrospective cohort study, we examined the postoperative radiographs of 131 femoral revision arthroplasty procedures using a monoblock, fully hydroxyapatite (HA)-coated titanium stem. Femoral offset, modified-global offset and leg length were measured of the operated and contralateral hips. Results: Femoral offset was restored to ±10 mm in 108 cases (82%), modified-global offset was restored ±10 mm in 93 cases (71%) and leg length was restored to ±10 mm in 102 cases (81%). There were 4 dislocations with a mean follow-up period of 38 months. Conclusions: Restoration of hip biomechanics is achievable with a monoblock stem and thus is a viable option in revision hip arthroplasty.Citation
