Our Summary

This research paper looks at the success of a specific type of hip replacement surgery, known as conversion total hip arthroplasty (THA). The researchers wanted to see if this type of surgery could be performed using the same implants as a first-time hip replacement, and if patients would recover without any major complications.

They studied 36 patients who had this surgery between 2008 and 2018, due to failed treatments for fractures in the upper part of their thigh bone. These patients were matched with others of the same age and sex who had either a primary hip replacement or a revision (second-time) hip replacement.

The researchers found that 72% of the patients who had the conversion surgery were treated with the same implants used in a primary replacement, and none of these patients had any major complications after their surgery. They also scored highly on measures of their health and wellbeing after the surgery.

The researchers conclude that the majority of conversion total hip replacements can be considered as similar to a primary replacement. They suggest that predicting the outcome of a hip replacement should focus more on the patient’s overall health and the potential technical difficulties of the surgery, rather than on whether it is a first-time or repeat procedure.

Doctor’s Tip

One helpful tip a doctor might give to a patient undergoing hip replacement surgery is to follow their post-operative care plan diligently. This may include physical therapy exercises, pain management, and restrictions on certain activities. By following these guidelines, patients can help ensure a successful recovery and minimize the risk of complications. Additionally, maintaining a healthy weight, staying active, and practicing good joint hygiene can help prolong the lifespan of the hip replacement.

Suitable For

Patients who are typically recommended for hip replacement surgery include those who have severe hip pain that limits their daily activities, have not found relief from non-surgical treatments such as physical therapy or medications, have arthritis or other degenerative joint diseases, have had a hip fracture, or have a condition that affects the hip joint such as avascular necrosis.

In the case of conversion total hip arthroplasty, patients who have previously had a failed treatment for fractures in the upper part of their thigh bone may be recommended for this type of surgery. This type of hip replacement may be considered when other treatment options have not been successful in relieving the patient’s pain and restoring function to the hip joint.

Overall, the decision to recommend hip replacement surgery, whether it is a primary replacement, revision surgery, or conversion surgery, should be based on a thorough evaluation of the patient’s individual circumstances, including their medical history, the severity of their hip pain and dysfunction, and their overall health and ability to undergo surgery and recovery.

Timeline

Before hip replacement:

  • Patient experiences chronic hip pain and stiffness that limits their mobility and quality of life.
  • Patient undergoes various non-surgical treatments such as physical therapy, medication, and lifestyle modifications to manage their hip pain.
  • Patient consults with an orthopedic surgeon to discuss the possibility of hip replacement surgery.
  • Patient undergoes pre-operative evaluations and tests to assess their overall health and suitability for surgery.

After hip replacement:

  • Patient undergoes hip replacement surgery, where the damaged hip joint is replaced with an artificial implant.
  • Patient stays in the hospital for a few days for post-operative care and rehabilitation.
  • Patient undergoes physical therapy to regain strength and mobility in the hip joint.
  • Patient follows a rehabilitation plan at home, including exercises and precautions to prevent complications.
  • Patient gradually resumes normal activities and experiences reduced hip pain and improved mobility.
  • Patient continues to follow up with their surgeon for routine check-ups and monitoring of their hip replacement.
