Summary

The purpose of this study is to determine if there is a difference in terms of length of hospital stay and post-operative outcomes between patients whose total hip replacement surgery is performed with a minimally invasive versus standard surgical approach.

Detailed description

Traditional techniques for total hip arthroplasty (THA) require complete visualization of the acetabulum and proximal femur since anatomic landmarks are crucial for correct orientation of the prosthetic components. All surgeons are taught that a wide surgical exposure is one of the most important factors in performing successful THA. Traditionally, it was impossible to achieve accurate fixation and orientation of the components without complete visualization of bony landmarks. These extensile exposures facilitate accurate implant alignment, but at the expense of more extensive soft tissue dissection. Little clinical research has been undertaken to relate the surgical approach to postoperative complications or patient function. Furthermore, despite the good overall results of THA, the recovery time to improved function can be lengthy. Blood loss is expected to be directly related to the extent of the surgical exposure and to influence patients outcomes. Based upon these facts, an important principle of arthroplasty surgery is to minimize the amount of soft tissue trauma while being able to achieve the surgical goal of reconstructing the arthritic hip joint. By definition, minimally invasive surgical (MIS) procedures result in less soft tissue disruption, which in turn should reduce pain, expedite healing, decrease recovery time, and potentially reduce the number of associated complications.

Conditions

• Hip Arthroplasty
• Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	Minimally Invasive Surgery	In minimally invasive surgery, the surgeon makes a shorter incision (about 10 cm or less) along the side of the thigh and replaces the hip through this smaller incision. The surgeon is able to do the surgery through a shorter incision by using special instruments which can guide him or her.
PROCEDURE	Standard Surgery	The standard way that an orthopaedic surgeon performs a hip replacement surgery is that they make a long incision (about 20 cm) down the side of the thigh and then replaces the hip joint through this long incision.
