[Long-term results of Insall's total condylar knee prosthesis (10-to-13-year follow-up)].

We have studied 10 to 13 years postoperatively the first 105 total knee arthroplasties using the Total Condylar, a semiconstrained prosthesis with sacrifice of the cruciate ligaments, inserted between 1979 and 1983, in 99 patients (6 were bilateral). The average age of these patients was 73.5 years at the time of arthroplasty.

[Long-term result of lumbar disk chemonucleolysis (a 8-12 years follow-up)].

Introduction: This study is an attempt to assess the effects of chemonucleolysis over an extended period of time (8 to 12 years follow-up).

Material And Methods: From 1981 to 1985, chemonucleolysis using Chymopapain was performed on 134 patients for the relief of radicular pain from herniated lumbar discs. The long term results were evaluated in 110 patients.
