GOAL: The goal of this prospective, non-randomized study is to compare early
functional and life-quality changes in primary total hip replacement (THR) with
minimally invasive anterior (MIA) and direct lateral (DL) approach. MATERIALS and
METHODS: Fourty (20 MIA, 20 DL) consecutive patients underwent primary THR
were operated by the same senior surgeon. Patients completed functional and lifequality
scores (Oxford Hip Score, Harris Hip Score, EQ-5D, EQ-VAS) before
operation and three times (2 and 6 weeks, 3 months) after the surgery. 6 months
after THR 10-10 patients underwent MRI examination to adjudge status of abductor
muscles. RESULTS: In MIA group both functional and life-quality scores showed
better results in first six weeks. Abuctor muscle strength was significantly greater.
Trendelenburg-limping was detected in more cases in DL group. Two weeks after
the surgery climbing a flight of stairs was normal and public transport could be used
by 80% of patients in MIA group. There were 4 operative complications in MIA group,
including 2 transient lateral femoral cutaneous nerve palsy, 1 greater trochanter
fracture, 1 haematoma. Postoperative hip dislocation was not detected. MRI
represented fatty atrophy of abductor muscles in DL group. CONCLUSIONS: It
seems that faster postoperative recovery can be achieved by MIA approach, which
have many financial and social benefits. It preserves muscles and tendons, which
probably can influence the long-term results. By preventing abductor muscles can
assure better gait pattern. Of course additional long-term studies are needed.
