Total Hip Replacement
What is Total Hip Replacement ?
Total hip replacement (THR), also known as total hip arthroplasty, is the definitive treatment for end-stage hip arthritis and other disabling hip conditions that have failed non-operative management. The damaged femoral head and acetabulum are replaced with prosthetic components, restoring a smooth, pain-free articulation. Total hip replacement is widely recognised as one of the most successful operations in modern medicine, reliably relieving pain and restoring function in the vast majority of patients.
Dr Razvan Stoita has specific expertise in performing total hip replacement through the direct anterior approach using a ceramic-on-ceramic bearing. This combination of a minimally invasive, muscle-sparing approach with the most advanced bearing technology available is designed to deliver the best possible outcome in terms of early recovery, long-term durability and return to an active lifestyle.
The Direct Anterior Approach
The direct anterior approach (DAA) accesses the hip joint through a natural interval between muscles, without cutting or detaching any muscle or tendon. The patient is positioned supine on a specialised operating table, and a short incision is made at the front of the hip. The surgeon works between the tensor fascia lata and sartorius muscles superficially, and between the gluteus medius and rectus femoris in the deeper layer, to reach the hip joint. Because no muscles are cut, the structures responsible for walking and hip stability remain intact throughout the operation.
Ceramic-on-Ceramic Bearing Technology
The bearing surface of a hip replacement is one of the most important factors determining its long-term durability. Modern ceramic-on-ceramic bearings, made from fourth-generation mixed-phase alumina-zirconia ceramic (such as BIOLOX® delta), offer significant advantages over traditional metal-on-polyethylene or metal-on-metal bearings:
Who is suitable?
Total hip replacement with ceramic-on-ceramic bearing through the direct anterior approach is indicated for:
Dr Stoita will review your symptoms, activity goals, and any existing imaging. A detailed clinical examination is performed to confirm the diagnosis and discuss whether this procedure is the right option for you.
Initial visitX-rays, MRI or other imaging may be used to confirm the diagnosis and assess the extent of the condition. In complex cases, 3D computerised modelling may be used to assist with surgical planning.
Pre-surgeryThe procedure is performed under anaesthesia using the most appropriate surgical technique for your condition. Dr Stoita uses minimally invasive approaches where possible to reduce recovery time and optimise outcomes.
Day of procedureMost patients stand and walk with a physiotherapist within hours of surgery.
Discharge home. Walking with a stick or crutches as a comfort aid.
Progressive increase in walking distance and return to light activities of daily living. No postoperative precautions are required.
Most patients are off walking aids and resuming driving and desk work during this phase.
Return to low-impact activities including walking, swimming and stationary cycling.
Gradual return to golf, hiking, skiing, tennis and other recreational activities.
Frequently Asked Questions (FAQ)
Hip arthritis usually develops over time rather than from a single cause. The most common reason is gradual wear of the joint cartilage with age. However, many people develop it earlier due to subtle issues with the shape of the hip, when the ball and socket don’t fit perfectly, it creates uneven pressure that slowly damages the joint. Previous injuries, such as fractures or dislocations, can also speed up this process. In some cases, genetics, inflammation, or increased load on the joint (including higher body weight or repetitive stress) contribute.
