There exists only limited scientific evidence concerning medium- to long-term benefits concerning minimally invasive (MI) total hip arthroplasty (THA). The investigators examined in a randomized study design 157 patients 8 years after THA, which were performed via 3 different surgical approaches.
In contrast to reported short-term advantages of minimally invasive (MI) total hip arthroplasty (THA) there exists only limited scientific evidence concerning medium- to long-term benefits.
The investigators therefore sought to answer the following questions: Is the functional medium-term outcome in THA patients with MI-anterior(MI-A) and MI-anterolateral (MI-AL) approach superior to those treated by direct lateral approach (DLA)? Is the level of life quality increased by MI-THA? Is patient satisfaction higher by MI-THA? Is the revision rate reduced by MI-THA?

Exclusion Criteria:
The minimally invasive anterior surgical approach was carried out using a modified Smith-Petersen access as described by Bender et al. (Bender et al. 2009) with the patient in supine position.
Other: surgical approach
For the minimally invasive anterolateral surgical approach, a modified Watson-Jones approach according to Röttinger (Rottinger et al. 2006) was applied with the patient in supine position.
Other: surgical approach
The direct lateral surgical approach was performed according to the technique described by Hardinge et al. (Hardinge et al. 1982) with the patient positioned supine
