The underlying aim of MIS hip replacement has been to reduce the tissue trauma, reduce blood loss and transfusion rates, to reduce post-operative pain, to hasten recovery of normal function and to improve scar cosmesis in THA. But unfamiliarity with the approaches also has the potential to increase complication rates, and this needs to be audited closely.
Materials and Method: A prospective study was carried out in 50 patients undergoing primary Total Hip Arthroplasty via mini incision posterior approach from March 2006 to January 2011. Intraoperative blood loss, surgical time, transfusion requirement, postoperative ambulatory status and complications were noted. Harris hip evaluation (modified) was used evaluate the outcome of the procedure.
Results: In our study we found out operating time was less, reduced Intraoperative blood loss and less postoperative blood transfusion. Other than that we did not find any difference in length of stay, post-operative ambulatory status, pain and final outcome according to Harris hip score. There was no significant difference in complication rates also.
Conclusion: Single-incision minimally invasive THR offers some perioperative advantages, including less blood loss, shorter operative time, and shorter length of stay. Little evidence exists with regard to any long-term differences between single-incision minimally invasive THR and standard-incision THR.
