SuperPATH Hip Replacement

What is SuperPATH Hip Replacement?

Supercapsular Percutaneously-Assisted Total Hip surgery, also known as SuperPATH surgery, is a revolutionary technique in orthopaedics, designed to minimise tissue damage and speed up recovery for patients who need a hip replacement. This novel method uses incisions measuring 2-3 inches (in some cases, 2-3cm) to perform the surgery without dislocating the hip or damaging the surrounding soft-tissue muscles and tendons. The level of pain is reduced, and recovery is accelerated.

With SuperPATH surgery, the muscles and tendons are preserved, and the natural structure of the hip is maintained. This procedure also ensures that the joint is replaced from within the capsule. Today, many surgeons have started incorporating the SuperPATH approach in treating their patients — and CK Birla Hospital, Punjabi Bagh was the first centre in North India to introduce it.

“This approach allows surgeons to perform hip replacement with a limited incision of approximately 3 inches. Instead of cutting through major muscles, they are gently retracted, ensuring the preservation of both the anterior and posterior capsules, as well as the short external rotators.” — Dr. Ashwani Maichand

What are the Benefits of SuperPATH Surgery?

• One of the best benefits of SuperPATH surgery is that it results in less postoperative pain. The incisions are very small, ensuring you don't experience pain or discomfort after surgery.
• As the size of the incision is too small, there is minimal blood loss during the surgery.
• Fewer post-surgery restrictions. Unlike conventional hip replacement, SuperPATH patients are not subjected to long-term limitations such as avoiding low chairs, crossing the legs, squatting, or bending forward — many begin walking the same day as surgery.
• Owing to the small size of the incision, there is minimal scarring, making this procedure more preferred from a cosmetic point of view.
• The recovery time in SuperPATH hip replacement is faster, with a shorter hospital stay.
• With this procedure, there is reduced risk of dislocation, and it gives you a natural feeling of a normal hip.
• Reduced need for post-operative dressings and lower drainage compared with conventional hip replacement.

Who are the Ideal Candidates for SuperPATH Surgery?

• Individuals suffering from severe and chronic hip pain that starts interfering with their routine activities are usually recommended this procedure.
• SuperPATH surgery is also good for patients with hip arthritis, osteoarthritis, rheumatoid arthritis, or any other form of arthritis affecting their hip joint.
• Patients with Avascular Necrosis (AVN) of the hip, where the blood supply to the bone is compromised, leading to bone tissue death.
• Patients who have sustained a hip fracture that cannot be repaired through other means are suitable candidates for this surgery.
• Patients with a higher body weight, for whom an anterior-approach replacement may be less suitable, often do well with SuperPATH.
• Individuals seeking a faster recovery are recommended to opt for SuperPATH surgery.

When SuperPATH May Not Be Suitable

While SuperPATH benefits a wide range of patients, it is not the right choice in every case. It may not be recommended for:

• Patients requiring revision (re-do) hip surgery.
• Patients with significant anatomical challenges that limit access through the supercapsular route.

In these cases, Dr. Maichand may recommend an alternative approach such as MIS hip replacement, DAA, or Bikini Incision hip replacement.

How do you prepare for SuperPATH Surgery?

During your first visit to the orthopaedic surgeon, they will conduct a thorough evaluation, including a review of your medical history, physical examination, and imaging studies such as X-rays and MRI scans to assess the current condition of your joint. You may also need to undergo a blood examination. Inform the surgeon if you are on any medication or have any pre-existing health conditions.

They may ask you to adjust the dosage of your medication. If you are a smoker, avoid smoking as it may interfere with the healing process. You will also be advised to participate in a preoperative physical therapy to strengthen your muscles around the hip and improve your overall fitness. It will hasten your recovery. You will further be advised to arrange for assistance at home during the initial recovery period.

How is SuperPATH Surgery Performed?

• The procedure starts with administering general anaesthesia. The effects of anaesthesia keep you relaxed, and you don't feel any pain or discomfort throughout the surgery.
• The surgeon makes a small incision in line with the femur and gently retracts the surrounding muscles and tendons to access the hip joint. No soft tissues are cut — both the anterior and posterior capsules are preserved, maintaining joint stability. In rare cases, the surgeon releases a tendon to gain better access.
• Specialised instruments are passed through this small portal. The acetabulum is prepared using a reamer inserted through a separate small incision, and the damaged cartilage is cleared from the socket.
• A dome-shaped acetabular implant is placed into the socket. The damaged femoral head is then removed and replaced by a femoral implant — a ball-on-stick component that fits precisely into the prepared neck of the femur, all without disturbing the surrounding muscles.
• Once the acetabular and femoral implants are secured, the surgeon puts them together to form the new hip joint.
• After testing stability and range of movement, the new joint is left in place and the incision is closed with sutures and staples.

What Does Recovery after SuperPATH Surgery Look Like?

It is normal to experience some pain and discomfort after the surgery. The care team will monitor your vitals and give you pain medication. Once you are discharged from the hospital, they will give you all the recovery instructions.

• Avoid high-impact activities until you are completely recovered.
• A physiotherapist will work with you during your recovery process. They will design an exercise plan including light movement and stretching to improve mobility and strengthen your muscles.
• Take medication as prescribed for pain management and do not self-medicate.
• Do not skip follow-up appointments with the surgeon. They will monitor your recovery process and make important adjustments.

Takeaway

SuperPATH surgery is a highly effective procedure that improves your mobility and offers long-term relief from chronic hip problems. This minimally invasive approach ensures faster recovery, less postoperative pain, and a lower risk of complications compared to traditional methods. For patients seeking maximum implant-placement precision, robotic-assisted hip replacement is also available as a complementary option.
