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 .
[Measurement of ground reaction forces after total hip arthroplasty using different surgical approaches].
AIM Benefits of less damage of soft tissues and muscles in minimally invasive hip replacement lead to expectations of better results in gait rehabilitation . The aim of the study is to evaluate post-operative walking ability in terms of different surgical approaches . METHOD 16 patients underwent a minimally invasive total hip replacement ( MIS group ) and 16 other patients got a THA using a transgluteal approach ( st and ard group ) . Differences in functional indices of ground reaction forces and symmetry indices were measured one day pre-operatively as well as 8 , 14 and 28 weeks post-operatively . The results were compared between the surgical approaches and to an age-matched healthy control group . RESULTS There are significantly reduced pain symptoms and a higher functional ability in both surgical groups 8 weeks post-operatively . There are no differences in gait parameters between the surgical groups after 28 weeks . Trends in gait velocity , temporal parameters and in functional indices of ground reaction forces show advantages for the minimally invasive group 8 and 14 weeks post-operatively . Patients do not reach the age-matched control group . CONCLUSION Obviously the immediate post-operative advantages of minimally invasive hip replacement provide better chances for gait rehabilitation compared to the transgluteal approach . Due to the complexity of the problem clinical and gait analysis studies should be linked more closely
