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 .
Rapid Rehabilitation and Recovery with Minimally Invasive Total Hip Arthroplasty
To assess the potential recovery rate of a  minimally invasive total hip replacement technique  with minimal soft tissue disruption , an accelerated rehabilitation protocol was implemented with weightbearing as tolerated on the day of surgery . One hundred consecutive patients were enrolled in this prospect i ve study . Ninety-seven patients ( 97 % ) met all the inpatient physical therapy goals required for discharge to home on the day of surgery ; 100 % of patients achieved these goals within 23 hours of surgery .  Outpatient therapy  was initiated in 9 % of patients immediately , 62 % of patients by 1 week , and all patients by 2 weeks . The mean time to discontinued use of crutches , discontinued use of narcotic pain medications , and resumed driving was 6 days postoperatively . The mean time to return to work was 8 days , discontinued use of any assistive device was 9 days , and resumption of all activities of daily living was 10 days . The mean time to walk ½ mile was 16 days . Furthermore , there were no readmissions , no dislocations , and no reoperations . Therefore , a rapid rehabilitation protocol is safe and fulfills the potential benefits of a rapid recovery with minimally invasive total hip arthroplasty
