Introduction: There is still limited evidence to support either direct lateral approach (DLA) or posterior approach (PA) for hip arthroplasty. Aim of this study is to compare the short-term clinical outcome of both approaches and discuss the findings from recent literature.
Methods: This is a cohort study of hip arthroplasty registry in our institution from January 2019 until January 2020. Functional evaluation using the Harris Hip score was carried out before surgery, three months, and six months after surgery. The primary clinical endpoint was determined as the intraindividual rise at the six months evaluation versus its preoperative level. Statistical analysis with T- test and Mann Whitney Test
Results: Total of 68 patients undergoing the surgery, equally distributed between the LA and PA group (n=34 for each). Postoperatively, no significant difference of HHS score was found between the two groups in three months for pain score (p = 0.534) and functional score (p = 0.772), also after six months for both pain (p = 0.995) and functional score (p = 0.790). The change in total HHS score from preoperative assessment to postoperative 3rd and 6th month between both surgical approaches was also not significantly difference (p = 0.693 and p = 0.505, respectively).
Conclusion: Hip arthroplasty that performed with posterior and lateral approaches resulted in similar intraoperative morbidity assessed through amount of blood loss and also similar clinical and functional outcome as assessed through length of stay and Harris Hip Score.
