The authors put forward a program of prevention of dysplastic arthrosis which is presented in graphic form with textual description. It has been worked out on the basis of the formerly elaborated conceptual model "Dysplasia of the joint-dysplastic arthrosis" and it is a complex of general medical prophylactic measures oriented towards the elimination of mutagenous environmental factors, i.e. towards prevention of morbidity and towards the treatment-and-rehabilitation orthopaedic measures directed at reduction of the risk of development of dysplastic arthrosis in the conditions of dysplastic lesion of the joint (prevention of the disease). The conditions necessary for carrying out this program are supposed to be: a diagnostic algorithm providing for revealing dysplastic lesions already at the preclinical stage; thorough quantitative and qualitative characteristics of the dysplastic process providing for planning of correct surgical interventions; prognostic evaluations presuming a probability of evolution of the dysplastic process and its outcome; and a system of stage-by-stage diagnostic and treatment-and-rehabilitation measures providing for achievement of the effect expected in each particular case. Three groups of surgical interventions have been pointed out: prophylactic, which are performed on the dysplastic joint in case of absence of dystrophic changes; therapeutic, which are performed in case of presence of reversible dystrophic changes (e.g. chondromalation at stages I and II); and palliative, which only result in temporary stabilization of the arthrosis process, i.e. leading to improvement.
