What is Hip Resurfacing Arthroplasty?

Hip resurfacing arthroplasty is a surgical procedure designed to treat hip joint damage while preserving more of the patient’s natural bone compared to traditional total hip replacement. In this procedure, the damaged surfaces of the hip joint are trimmed and capped with a smooth metal covering. This technique is particularly beneficial for younger, more active patients who may benefit from retaining more of their natural bone structure.

How is Hip Resurfacing Arthroplasty Done?

1. Preoperative Assessment: A thorough evaluation, including medical history, physical examination, and imaging studies such as X-rays or MRI, is conducted to plan the surgery.
2. Anaesthesia: The procedure is performed under general anaesthesia or regional anaesthesia (spinal or epidural), ensuring the patient is pain-free during the surgery.
3. Incision: An incision is made over the hip to access the joint.
4. Preparation of Joint Surfaces: The surgeon trims the damaged cartilage and a small amount of bone from the surface of the femoral head (the ball of the hip joint).
5. Implantation of Metal Components: A metal cap is placed over the reshaped femoral head, and a matching metal socket is implanted into the hip socket (acetabulum).
6. Closure: The incision is closed with sutures or staples, and a sterile dressing is applied.

Why is Hip Resurfacing Arthroplasty Done?

Hip resurfacing arthroplasty is performed to relieve hip pain and improve joint function in patients with hip joint damage. This procedure is often chosen for younger, more active patients who may benefit from the bone-preserving nature of hip resurfacing. It is particularly advantageous for those who wish to maintain a high level of physical activity post-surgery.

Who Might Need Hip Resurfacing Arthroplasty?

Hip resurfacing arthroplasty is suitable for individuals who experience:

• Severe hip pain that interferes with daily activities such as walking, climbing stairs, and getting in and out of chairs.
• Persistent pain despite the use of pain medications and physical therapy.
• Limited range of motion in the hip joint.
• Hip joint stiffness that impairs mobility.
• A desire to maintain a higher level of physical activity post-surgery.

Conditions Treated with Hip Resurfacing Arthroplasty

• Osteoarthritis: Severe degeneration of the hip joint due to wear and tear.
• Rheumatoid Arthritis: Chronic inflammation causing joint damage.
• Avascular Necrosis: Loss of blood supply to the hip joint leading to bone death.
• Hip Dysplasia: Abnormal development of the hip joint.
• Post-Traumatic Arthritis: Arthritis following a hip injury.

Recovery Times

Recovery time after hip resurfacing arthroplasty varies depending on the individual’s condition and adherence to rehabilitation. Generally:

• Hospital Stay: Patients usually stay in the hospital for 2-4 days post-surgery.
• Initial Recovery: Walking with the aid of crutches or a walker is encouraged within a day after surgery.
• Physical Therapy: A structured rehabilitation programme begins soon after surgery to regain strength and mobility.
• Full Recovery: Most patients resume normal activities within 3 to 6 months, though full recovery can take up to a year, especially for those returning to high-impact activities.

Tips for a Good Recovery

1. Follow Postoperative Instructions: Adhere to your surgeon’s guidelines on wound care, activity restrictions, and medication.
2. Physical Therapy: Engage in prescribed physical therapy exercises to enhance strength and mobility.
3. Home Modifications: Make necessary adjustments at home, such as installing grab bars and using a raised toilet seat.
4. Healthy Diet: Maintain a balanced diet to support healing and overall health.
5. Avoid High-Impact Activities: Steer clear of activities that may strain the resurfaced hip joint, such as running and jumping, until cleared by your surgeon.
6. Attend Follow-Up Appointments: Regular check-ups with your surgeon to monitor progress and address any concerns.

Conclusion

Hip resurfacing arthroplasty is an advanced and effective solution for individuals suffering from severe hip joint damage who wish to preserve more of their natural bone and maintain an active lifestyle. By capping the damaged surfaces of the hip joint with metal components, this procedure can significantly reduce pain and improve mobility.
