At Bangkok Hospital Phuket, we offer hip replacement using the Direct Anterior Approach (DAA) — a minimally invasive technique that allows surgeons to replace the hip joint without cutting through major muscles. This leads to faster healing, reduced pain, and early return to daily life. 

Key Benefits of DAA 

• ❌ No major muscle cutting → minimal tissue trauma 
• ✅ All patients walk within 24 hrs after surgery 
• 🔻 Lower dislocation risk than traditional approaches 
• ⏱ Quicker return to independence, ideal for seniors and working adults 
• 📈 2024 Patient Outcomes (31 patients) 

What is HOOS-PS? 

A clinical score evaluating hip mobility — the lower the score, the better the function 

What is QOL (Quality of Life)? 

A measure of how well patients return to meaningful daily activities, such as walking, sitting, sleeping, and overall well-being 

Timepoint	HOOS-PS	QOL (%)
Immediate Post-op	10.57	54.17%
2 Weeks Post-op	2.57	87.50%

Clear improvement in mobility and quality of life within 2 weeks 

Pain Reduction (Visual Analog Scale) Patients undergoing DAA reported less pain and faster relief 

Time	DAA	Standard
Pre-op	4.8	6.8
Immediate Post-op	2.4	5.7
1 Week	0.3	4.6
4 Weeks	0	2.4

Walking & Return to Normal Activity 

Activity	DAA	Standard
Ambulate within 24 hrs	✅ 100% of cases	✅ 80% of cases
Walk without aids	1–7 days	1–6 weeks

Length of Hospital Stay 

Case Type	DAA	Standard
Trauma	6–20 days	10–20 days
Chronic	3–10 days	5–14 days

More Than Just Surgery — A Patient-Centered Path to Healing 

DAA is more than a technique — it reflects a care philosophy focused on patient priorities, including: 

• Walking and recovery sooner 
• Faster return to daily routines 
• Less reliance on caregivers 
• Reduced complications and long-term costs 

Because we believe that a successful surgery is measured by life after the operating room.
