After a very short résume of his presentation in sept 2000 for the ISTA Conference in Berlin, the author looks briefly at the results of T.R.A.C knees after, what is now, four years of clinical follow-up.

Given the bad results this far regarding the femoropatellar joint and the uncemented version. M.D. François Pilon moves on to present an original concept, the latest evolution in knee systems: the rotary plateformed and posterior stabilised prosthesis, which offers a large congruence of polyethylene.

Originality of the newwave prothesis:

-Developement of a non-posteriorstabilised, fixed-plateau, prosthèses (GALICA, 8 yrs on !)

-Use of GoldFinger System (4 yrs on)

-First implantations in Sept. 00 (only simple clinical impressions today)

Clinical, X-ray follow-up system: All NewWave users can consult the computer Letterbox : newwave@groupe-lepine.com to have current results (up to the minute)

A NewWave reimplantation replacement prosthesis is at the moment on the drawing-board.

In four years time, Dr Pilon hopes to be presenting the real five year follow-up H.S.S. results of NewWave to the I.S.T.A..
