[Articular chondrocalcinosis and sliding knee prosthesis].

The authors examined 24 files, involving 24 cases of arthroplastic knee surgery and revealing an articular chondrocalcinosis which was histologically proven. The mean post-operative follow-up took place in 30 months (1 to 5 years). The results were neither spectacular nor catastrophic. The overwhelming majority of the patients were satisfactory. 60% of those who had undergone surgery showed good objective results. Radiological aggravations were rare; the latter were not necessarily parallel to the clinical results. In conclusion, chondrocalcinosis does not appear to be an aggravating factor in the prognosis for sliding unicompartmental arthroplastia. The results were completely comparable to those in cases of osteoarthrositis without calcinosis. In both cases, the same encouraging results were observed, as well as the same doubts and uncertainty as to the future.
