What is Revision Total Knee Replacement?

Revision total knee replacement is usually considered when knee replacement surgery fails. During the procedure, your orthopedic surgeon may replace the damaged parts of the original prosthesis with the new ones. The procedure aims to provide relief from pain and improve mobility and function of the knee.

Revision total knee replacement is quite different from Primary total knee replacement surgery where the former procedure is a time-consuming, more complex procedure and requires extensive planning due to the use of specialized implants and tools to achieve a good result.

When is this surgery recommended?

A revision knee replacement surgery is usually recommended in conditions like:

  • Infection following knee replacement surgery, which usually is rare due to extreme precautions taken in the operation theatre. If an individual notices unusual swelling, fluid leakage, tenderness after undergoing knee replacement surgery then try contacting the surgeon immediately.
  • Aseptic Loosening, instability, and malalignment of the implants may cause increased soft-tissue laxity around the knee which may alter the knee function and require revision total knee replacement surgery.
  • Periprosthetic fractures.
  • Long-term wear and tear of the implants may also be a reason where Revision Knee replacement is considered.
  • Patient-Related Factors like obesity may increase the incidence of implant failure, age, and activity level of the patients can also contribute to implant failure, younger or more active patients tend to have a higher rate of revision than older, and less active patients. 

What is the procedure?

During the procedure, your orthopedic surgeon may remove the damaged implant or prosthesis which was fixed during total knee replacement. In case of damage to the bone, the orthopedic surgeon may find it difficult to use standard total knee implants for revision knee replacement. However, in most cases, the surgeon may use specialized implants with thicker, longer, stems that can fit deeper inside the bone and provide extra support.

Revision total knee surgery is a complex procedure that requires specialized implants and tools, extensive preoperative planning, and prolonged operating time.

What is post-surgery feedback?

More than 90% of patients who undergo revision total knee replacement can expect to have good to excellent results. Although it’s not always possible to have complete pain relief and restored function the patients can find pain relief with improved stability and function.
