A study issued in the journal 'The Surgeon', portrayed that as per the available reviews, the direct anterior approach (DAA) has superior functional outcomes than the other methods in the immediate postoperative period after primary total hip arthroplasty with no increased risk of complications.

But, there was no evidence to assist the precedence of any approach after six weeks postoperatively.The supporters of the direct anterior approach (DAA) for THAs reported earlier recovery with no increased complications whereas others reported higher complication rates.Fatih Kucukdurmaz et al. conducted a meta-analysis of randomized controlled trials (RCTs) to distinguish between the outcomes of the DAA versus other surgical approaches in case of primary THAs.

On the whole, 18 RCTs suitable for detailed extraction of the data were recognized. These RCTs had a total of 1661 patients with a mean age of 62 years (range 55 to 69). Utilizing DAA led to a significant improvement in the Harris Hip score by a mean of 5.6 points and the WOMAC score by a mean of −3.1 points at 6 weeks postoperatively, There was also a reduction in the analgesic requirements on the day of surgery and pain scores on day one after the operation. DAA was concerned with a smaller incision (−3.2 cm 95% CI −3.3 to −3.1, p < 0.01, I2 99%) and there was no significant difference in complication rates amidst the study groups.
