Quick Answer
The Direct Anterior Approach (DAA) reaches the hip through a natural gap between muscles at the front — no muscles are cut — allowing most patients to walk the same day with no movement restrictions. The posterior approach cuts through gluteal muscles at the back, requiring 6-8 weeks of restrictions while they heal. Dr. Pulak Vatsya specialises in DAA hip replacement at StepUp Joints, Lajpat Nagar, and uses it as his standard approach for most eligible patients because of the faster, restriction-free recovery.
The Core Difference
Both approaches replace the same hip joint with the same implant. The difference is the path taken to reach it. Dr. Pulak Vatsya explains that the Direct Anterior Approach works between muscle planes without cutting any major muscles, while the posterior approach requires detaching the gluteal muscles at the back of the hip.
This single difference — cutting muscles or sparing them — is what determines recovery speed, movement restrictions, and dislocation risk. It is why Dr. Pulak Vatsya trained specifically in DAA at AIIMS New Delhi and Tokyo Sports & Orthopaedic Centre, Japan.

Why Dr. Pulak Vatsya Prefers DAA
Dr. Pulak Vatsya uses the Direct Anterior Approach as his standard technique for most eligible hip replacement patients at StepUp Joints, Lajpat Nagar. The reasons are practical and patient-focused:
-
Patients walk the same day and return home within 48 hours.
-
No restrictions on sitting, bending, crossing legs, or sleeping position.
-
Lower dislocation risk provides greater long-term confidence.
-
Particularly valuable for younger patients with avascular necrosis (AVN).
The posterior approach remains a proven, reliable operation. But for eligible patients, Dr. Pulak Vatsya finds the DAA recovery experience is significantly better. Very few surgeons in South Delhi perform DAA as their default technique.
