Hip replacement surgery is one of the most frequently performed procedures in orthopedics. In recent years, the minimally invasive anterior approach has revolutionized the patient recovery journey. We discussed this advancement with Dr. Daniele Caviglia, an orthopedic surgeon at our clinic.

Doctor, what exactly is a minimally invasive anterior approach hip replacement, and how does it differ from traditional techniques?

“The minimally invasive anterior approach, also known as the DAA (Direct Anterior Approach), is a surgical pathway that allows us to access the hip joint while completely preserving the surrounding muscles—without cutting or detaching them from the bone. By eliminating muscular trauma, this technique significantly reduces post-operative pain, ensures a faster recovery, and lowers the risk of prosthesis dislocation.”

What are the primary benefits for the patient compared to conventional surgery?

“The advantages are extensive and positively impact the entire perioperative journey:

• Immediate mobilization: Patients can resume walking on the very day of surgery;

• Reduced post-operative pain: Due to the minimal impact on soft tissues;

• Shorter hospital stays: In many cases, patients are safely discharged within 2 to 3 days;

• No post-operative postural restrictions: Giving patients greater freedom of movement immediately;

• Smaller incisions: Resulting in minimal scarring and a superior aesthetic outcome;

• A faster return to daily life: Significantly reducing social, personal, and occupational downtime.”

Who is the ideal candidate for this type of procedure? Are there any contraindications?

“This technique is highly indicated for the vast majority of patients suffering from hip osteoarthritis (coxarthrosis)—the progressive degeneration of the hip joint—who no longer respond to conservative treatments. Age itself is not a limiting factor; we routinely treat patients ranging from 40 to 90 years old. However, certain unique anatomical anomalies may require an individualized assessment. This is why we always conduct an exhaustive pre-operative study at our clinic, utilizing digital weight-bearing radiographs and, when necessary, 3D CT scans.”

How is the operation actually performed? Should patients be concerned about pain?

“The procedure typically takes about 60 minutes and is performed under either spinal or general anesthesia. Patients feel absolutely nothing during surgery. Post-operative pain is meticulously managed using modern, multimodal analgesic protocols, which minimize the reliance on morphine and opioids. The vast majority of our patients report that any discomfort within the first 24 hours is highly manageable.”

What does the rehabilitation process look like after the procedure?

“Thanks to the anterior approach, rehabilitation is dramatically accelerated. Within just a few hours of surgery, a physiotherapist guides the patient through taking their first steps. On day one, they walk using a walker; by day two, they transition to crutches. By the fourth week, most patients are walking completely independently. Activities such as driving, swimming, or cycling can typically be resumed within 6 weeks. At the Arsbiomedica Clinic, every patient benefits from a tailor-made rehabilitation program, seamlessly coordinated by our in-house physiotherapy department.”

What is the lifespan of a modern hip prosthesis? And what happens if it wears out over time?

“Next-generation implants have an estimated lifespan exceeding 25 years. International orthopedic registries consistently demonstrate survival rates above 90% at the 25-year mark. Should a revision surgery eventually become necessary, the procedure can be precisely planned with excellent clinical outcomes. To monitor the prosthesis over time, it is vital to undergo routine annual follow-ups with standard X-rays.”

What is your final message to patients who are considering this surgery but still feel hesitant or fearful?

“My advice is not to delay the decision for too long. We frequently see patients who have endured years of chronic pain, restricted mobility, and compromised lifestyles. Opting for an anterior approach hip replacement is not a defeat—it is a proactive choice to reclaim your quality of life. Months down the road, the most common sentiment we hear from patients is that they wish they had undergone the procedure much sooner. The key is to place your trust in a specialized center and view the surgery as the first step toward a life of renewed, pain-free mobility.”
