Text
The overall quantitative knee score and range of motion were associated with changes in joint line.We investigate 34 knee revisions in 33 patients, 28 females and 5 males. Pre OP in 15 cases prosthetic
joint li ne was greater than 15 mm proximally to the tip of the fibular styloid and less than 16 mm distal to the medial epicondyle. We saw hyperextension of 10 deg or more and midflex instability. We reconstruct the joint line with the Wallaby III Revision System.The special technique was discribed.
5 years post OP the joint line position was 10 mm(+/-2mm) proximally to the fibular styloid and 25 mm( +/ -2mm) distally to the medial epicondyle.
In all cases normal extension,no midflex instability and in 14 of 15 cases stable situation for varus valgus was seen.
The insall score increase from 25.5 to 84 and the function score from 40.8 to 89.
Conclusion
we reconstruct the joint line in TK Revision with the Wallaby III Revision System.After 5 years it leads to improved knee score,improved ROM and improved ligamentous stability. Exact joint line reconstruction is necessary for good results and good late results in TK Revision.
