HIP ARTHROPLASTY
As the body ages our joints can wear. In the hip joint this is especially painful. Other causes of joint degeneration can give rise to debilitating hip pain as well. Luckily, orthopaedic science has progressed to a point where we can effectively manage most of these problems with a hip replacement.
The procedure consists of replacing the diseased joint with a mechanical one. Pain relief is dramatic and complications are rare. Possible complications would include deep venous thrombosis in about 1% of patients, infection in about 0.3% of patients and other less common problems such as fracture, bleeding, dislocation etc.
The prosthesis lifespan is about 95% after 10 years and 90% after 20 years depending on the series you used.
Different surgical approaches are used depending on the skill and preference of the surgeon. I mostly use the Anterior Minimally Invasive Approach as my patients have less pain, mobilize earlier, bleed less and have less chance of dislocation,
