Use of Leeds–Keio Connective Tissue Prosthesis (L–K CTP) for reconstruction of deficient extensor mechanism with total knee replacement

Purpose
This study was carried out in order to assess the results of reconstruction of a deficient extensor mechanism in the presence of a total knee replacement (TKR) using the Leeds–Keio Connective Tissue Prosthesis (L–K CTP).
Methods and results
The L–K CTP is available as flat tapes constructed from polyester in an open weave structure. It was used to reinforce and reconstruct the extensor mechanism, which was deficient in three patients who had undergone total knee replacement or were about to undergo total knee replacement. Two cases had extensor mechanism deficiency as a complication following total knee replacement while the third case had extensor mechanism deficiency at the time of the primary knee replacement. The average follow-up was 2 years (range of follow up was 12 to 48 months). All three cases showed good results with no extension lag and good range of movement at follow up.
Conclusion
The use of L–K CTP for reconstruction of the knee extensor mechanism offers a good option for the management of the uncommon but difficult problem of extensor mechanism deficiency in patients with a total knee replacement.
