Hip replacement surgery is generally carried out for osteoarthritis of the hip. There are some other indications for this surgery including other types of arthritis, previous fracture, dysplastic hip, etc.
Hip replacement surgery involves removing the damaged head of femur (ball of the hip joint) and preparing the socket, in order to accommodate a new ball and socket joint.
Types of Hip Replacement
There are several types of hip replacement. The two main types are cemented or uncemented based on how they are fixed to your bones.
Commonly used bearing surfaces of the hip joint are
1. Metal on plastic
2. Ceramic on plastic
3. Ceramic on ceramic
I choose the type of fixation and bearing surfaces based on the quality of bone stock as well as functional needs of individual patient
Risks and Benefits
Overall, total hip replacement is one of the most successful operations in modern day surgery. In my practice, success rate of a total hip replacement is in the range of 90-95%. Pain relief and improvement in the quality of life is substantial in vast majority of patients. It improves mobility and alleviates pain during day-to-day activities. It also helps patients maintain an independent life with little/no dependence on carers/family.
Risks of total hip replacement include infection (around 1%), dislocation (1-2%), bleeding, DVT (clots in your leg), PE (clots in your lung), leg length discrepancy, loosening, wear, medical and anaesthetic complications. Precautions are taken in order to minimize all the above risks e.g. use of antibiotic prophylaxis and specialized laminar air flow theatres to minimize the risk of infection, use of blood thinning medications and mechanical methods to reduce the risk of clots, etc.
Rehabilitation and recovery
You are generally admitted to the hospital on the day of surgery. Average length of stay in the hospital is 3-4 days. During the hospital stay, a multi-disciplinary team including orthopaedic team, ward doctor, nursing staff, physiotherapist and occupational therapist, treats you. Once you and the team are happy with the progress, you are discharged from the hospital.
Post-operative mobilization includes use of walking aids like walker or crutches to begin with. You can subsequently use walking stick/s until independent mobility can be achieved.
You can expect some swelling and redness around the wound and of the lower leg for few weeks. Generally by 6 to 12 weeks, functional recovery can be expected in most patients.
Implants of my choice
I choose the implants for hip replacement very carefully for each patient. The type of hip replacement used in my clinical practice has a very long track record (>25 years) with excellent long-term survival. Currently, my preferred implants are Corail Femoral stem system (uncemented stem manufactured by Depuy Synthes), C stem AMT (cemented stem manufactured by Depuy Synthes), Pinnacle cup system (uncemented cup manufactured by Depuy Synthes) and Marathon cup (cemented cup manufactured by Depuy Synthes).
