The meta- analysis of the current evidence base showed that minimally invasive THA is associated with a significantly increased risk of transient lateral femoral cutaneous nerve palsy ( p = 0.006 ) with no significantly better outcome
Over the past decade , minimally invasive surgery has gained popularity as a means of optimising early postoperative rehabilitation and increasing patient satisfaction and cosmesis following  total hip arthroplasty ( THA ) .
However , this surgical exposure has also been associated with increased risk of iatrogenic nerve injury and implant mal-positioning due to limited visibility compared to conventionally larger surgical incisions .
The purpose of this meta- analysis was to compare the outcomes of these two surgical exposures .
Operative and Patient Care Techniques for Posterior Mini-incision Total Hip Arthroplasty
Technical and patient care improvements have occurred with the posterior mini-incision total hip arthroplasty . We hypothesized that these changes would provide better results for patients . The clinical and radiographic results of 100 total hip arthroplasties done with the posterior mini incision between January 2004 and October 2004 were compared with 100 mini-incision total hip arthroplasties done between December 2001 and September 2002 . There were no differences in diagnosis , age , and body mass index of the patients in each group . Component positions were not compromised in either group . There were improvements in the 2004 group with decreased hospital stay , reduction of postoperative pain and opioid analgesic use , reduced use of assistive devices , and earlier muscle recovery . In the 2004 group there were no complications of infection , dislocation , or sciatic palsy . The posterior mini-incision operation has shown improved results with experience and changes in technique and patient care treatment .
