Intra-articular occurrence is even more rare. To our knowledge, this case is one of only 2 reported intra-articular EMC cases of the knee free of local recurrence and\/or amputation at follow-up. This case is also distinctive for being fluorescence in-situ hybridization\u2013negative for the typical EMC-balanced translocation t(9;22) which fuses\n                      <jats:italic
