BACKGROUND: To characterize the histological changes within the posterior calcaneal cartilage in @entity1 with @entity924 ( @entity924 ) and test the relationships between severity of the histological changes and level of functional impairment. METHODS: Sixteen posterior calcaneal wall specimens of @entity1 with @entity924 who had posterior calcaneal ostectomy were investigated. @entity1710 - @entity1711 stain, @entity11979 stain, Polarized light microscopy, and Masson Trichrome stain were used to characterize histological changes. Changes within the posterior calcaneal wall cartilage were graded according to @entity571 Research Society International (OARSI) criteria. Functional scores were completed at the time of surgery according to the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score. RESULTS: Mean age of @entity1 was 48.9  years. Histological findings within the posterior calcaneal wall cartilage specimens were consistent with arthritic changes. OARSI grading indicated Grade 2 changes in one specimen, mean AOFAS score 60; Grade 3 changes in three specimens, AOFAS score 73.7        2.5; Grade 4 changes in four specimens, AOFAS score 44        21.4; Grade 5 changes in eight specimens, AOFAS score 48        9.9. Higher OARSI grades were correlated with lower AOFAS scores (rho   =   -0.65, p   <   0.01). CONCLUSIONS: Degenerative arthritic changes of the posterior calcaneal wall cartilage characterize @entity1 with @entity924 and the severity of such changes is directly correlated to the @entity73 .

Insertional Achilles XXXX is associated with arthritic changes of the posterior calcaneal cartilage: a retrospective study.
