Revision Total Knee Arthroplasty

Feature Summary

        We have highly experienced surgeons to deal with common but challenging problems during a revision total knee arthroplasty surgery, including infection, torn ligaments, massive bone loss, poor alignment or poor implant position. The goal of a revision total knee arthroplasty surgery would be to make the affected knee joint stable, painless, with correct alignment and functioning well.

 

Overview

        Recurrent pain, swelling and disability of the knee joint after a total knee arthroplasty surgery is problematic. Common causes are listed as below:

  • Infection

        Clinical presentations of an infected knee joint include pain, swelling, erythematous skin, purulent discharge and local heat. Proper assessment, diagnosis, and management of periprosthetic joint infection (PJI) is the key to eradicate infection.

  • Instability

        Patients may present with recurrent knee effusion, weakness, especially from sitting to standing, or refractory tendinitis around the knee joint. Revision of partial or all components may be necessary to regain stability.

  • Wear or implant loosening

        Longevity of the prosthesis depends largely on patients’ age and activity level. Wear or implant loosening may happen many years after primary total knee arthroplasty surgery, with presentation of painful sensation over a previously well-functioning, painless joint. X-ray is the main diagnostic image modality of this condition.

  • Implant malposition

        Patients may present with persistent pain, especially during walking or bending his/her knee following primary total knee arthroplasty surgery.

        Above all, a knee operated with total knee arthroplasty should be painless, able to bear weight and to do range of motion without difficulty. Potential problems or complications following total knee arthroplasty surgery should be well assessed by experienced surgeons in our team.

 

Procedures and Features

        Our team is composed of experienced orthopedic doctors, infectious disease specialist and radiologists who can make accurate diagnosis and management of a painful, malfunctioning knee joint following total knee arthroplasty surgery.

        We have set up one of the largest bonk bank in Taiwan, which makes us easy to deal with different degrees of bone loss during a difficult revision surgery.

        Operation time largely depends on surgical plan, which may vary from about 1 to 3 hours. Range-of-motion exercises and weight-bearing program will be decided by orthopedic doctors according to intra-operative findings. Most of the patients can walk without weight-bearing restrictions and start range-of-motion exercises immediately after surgery.

 

Estimated cost

        The procedure cost is around 600,000 NTD, depends on the actual medical expenses.
