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 .
Comparison of immediate postoperative walking ability in patients receiving minimally invasive and standard-incision hip arthroplasty: a prospective blinded study.
Minimally  invasive hip arthroplasty  is thought to result in less soft tissue damage , earlier ambulation , and improved rehabilitation . This prospect i ve blinded cohort study objective ly analyzed early functional walking ability by stride analysis 2 days postoperatively . Ninety-five patients were analyzed , 43 of who received the minimal incision and 52 the traditional incision .  Patients , physiotherapists , and assessors were blinded to the incision used . Velocity , cadence , stride length , operated and nonoperated limb step-length , and the ratio of step length of the operated to nonoperated limbs were recorded . No significant differences in any of these variables were shown between the minimal-incision and traditional-incision groups . This study demonstrates no functional benefits of the minimally invasive incision over the st and ard one in terms of early walking ability
