Hip Joint is the largest and the most stable joint in the human body.It is the largest ball socket joint, socket cup formed by the Acetabulom, which is the past of pelvic bone and the ball is formed by the upper end of the thighbone (Femur). The ligaments and the hip provide stability, acting in coordination during each and every degree of mobility in our day to day activities.
Common Causes Of Hip Pain
- OSTEOARTHRITIS: Age-related wear and tear seen in people of 50 years and beyond where bones rub against each other causing pain and stiffness.
- Rheumatoid ARTHRITIS: An autoimmune disease in which the synoniuimin the cartilage destroys the cartilage.It is also termed as Inflammatory Arthritis.
- AVASUCLAR NECLASIS (AVN): Any injury to the hip, previous dislocation, childhood disease, long-term use of steroids smoking and alcoholism may result in lack of blood supply, leading to the collapse, deformation and arthritis of the Hip.
- Past Traumatic Arthritis: Any major injury to the hip followed by surgery and its failure can lead to arthritis causing pain and deformity.
Total Hip Replacement
In Total Hip Replacement surgery, the damaged bone and cartilage is removed and replaced with prosthetic components. The damaged femoral head is removed and replaced with a metallic stem that is placed into the hollow centre of the femur. A metal or ceramic ball is placed on the upper part of the stem. The damaged cartilage surface of the socket (Acetabulum) is removed and replaced with metal socket to allow for a smooth gliding surface.

When is Surgery Recommended?
- Hip pain that limits everyday activities like walking stairs, bending etc.
- Pain at rest – day or night
- Inadequate relief from medication, physiotherapy and walking aids.
Medical history of the patient is first checked. Physical examination includes hip mobility, pain score strength alignment. X-rays show degeneration/deformation while MRI is helpful in soft tissues condition and early stages of AVN.
Most patients who undergo Hip replacements experience significant/dramatic pain relief and improvement in the ability to perform daily activities. With ageing, the prosthetic material between the head the socked (liner) begins to wear. With appropriate activity and lifestyle modification, hip replacements can last for years.
Once the need for surgery has been decided, the patient will undergo a set of a surgical profile, medical /cardiology clearance and preanesthetic evaluation. The implant to be used will be chosen according to the patient requirements and is based on the quality and strength of the bone.
The patient will be staying in the hospital for 2-3 days initially for pain management. The wound heals after approximately 2 weeks of surgery.
Post Operative Care
There has to be a graduated walking program followed by normal activities such as sitting,standing and climbing stairs in 3-4 weeks.
Possible Complications of Surgery
The rate of complications in hip replacements in as low as 2% worldwide. These include infections, blood cots, limb length inequality, dislocation etc.
Hip replacement in a boon for the patients with severe hip pains impacting the day to day activity. The success of the surgery is based on the selection of the patient, education of the patient before and after surgery, necessary evaluation and right expert intervention.
