Revision Knee Replacement

Revision knee arthroplasty involves the replacement of a previously implanted artificial knee joint with a new prosthesis. In severe conditions patients need to undergo revision knee arthroplasty in Delhi,

The conditions include wear and tear of the original joint leading to loosening or instability, infection around the implant, bone loss or damage around the knee joint, or failure of the initial knee replacement due to mechanical issues.

Revision knee arthroplasty involves the replacement of a previously implanted artificial knee joint with a new prosthesis. In severe conditions patients need to undergo revision knee arthroplasty in Delhi,

The conditions include wear and tear of the original joint leading to loosening or instability, infection around the implant, bone loss or damage around the knee joint, or failure of the initial knee replacement due to mechanical issues.

The rising cases of revision knee arthroplasty are due to ageing population, resulting in more individuals with existing knee replacements needing surgeries as these prosthetic joints age and face complications. Plus, younger patients who are undergoing knee replacements will likely require revisions over their lifetimes.

Initial knee replacements fail due to following reasons.

1. The wear and tear of the artificial joint components over time, causing implant loosening or instability.
2. Infections around the implant, causing failure.
3. Bone loss or damage around the knee joint
4. The implant-related complications such as fractures or dislocations can necessitate revision surgeries.

Patients can adopt following measures to prolong the life of their knee replacements:

1. Maintaining a healthy weight reduces stress on the artificial joint
2. Engaging in appropriate physical activities, following post-surgery rehabilitation programs,
3. Taking prescribed medicines for preserving the functionality of the implanted joint

Following risk factors can lead to the need of revision knee arthroplasty:

1. Obesity increases stress on the artificial joint causing earlier failure.
2. Other factors include a history of previous joint surgeries, inflammatory joint diseases like rheumatoid arthritis, osteoporosis leading to weakened bones, and certain occupations or activities that subject the knee joint to repetitive stress

Diagnosing a failed knee replacement involves clinical examination imaging studies like X-rays, CT scans, or MRIs to assess implant position, bone quality, and signs of wear or instability. There may be a need for Laboratory tests, such as joint fluid analysis in case of suspected infection in confirming diagnoses.

Yes, revision knee arthroplasty has challenges due to the altered anatomy and loss of bone stock from the initial surgery. Ortho Surgeons in Delhi have to address bone defects or failure to ensure stable implant fixation. In some cases, bone grafting or metal augments, are necessary to reconstruct bone deficiencies. Additionally, scar tissue adds complexity to the surgery.

Enhanced implant surfaces with improved coatings provides better integration with surrounding bone, giving stability and longevity. Modular implant systems allow flexibility, enabling surgeons to address bone defects. Highly cross-linked polyethene components reduced wear rates, potentially extending implant lifespan.
