CONCLUSIONS: We concluded that prognosis of SCH is worse than conventional one and we speculated this is due to the difficult site of the tumor (intraarticular), diagnostic delay and inappropriate previous treatments. [ncbi.nlm.nih.gov]

According to Campanacci et al. the prognosis of SCH is comparable to that of conventional CHS and depends on the histological grade of malignancy of the lesion (1). [atm.amegroups.com]

No etiological factors can be indicated, even though in some cases there is a history of trauma. No familiar cases were reported. Surgery ended up with amputation in 59.7% of cases. Local recurrence rate was 28.3%. [atm.amegroups.com]

ETIOLOGY: The etiology of synovial chondromatosis is not known. Some suspect that it is due to synovial irritation. This may be from trauma or possibly from infection, but this is unclear. No organism has ever been cultured. [gait.aidi.udel.edu]
