             (a)    an acute meniscal tear of the knee;
             (b)   calcium pyrophosphate deposition disease (pseudogout);
             (c)   dialysis-related amyloidosis;
             (d)   gout;
             (e)   internal derangement of the knee;
             (f)    Lyme disease;

             (h)   pigmented villonodular synovitis;

         (3)          having an injury or disease which causes synovitis of the affected knee joint at the time of the clinical worsening of popliteal cyst;
            Note: Examples of an injury or disease which can cause synovitis of the affected knee joint include:
             (a)    an acute meniscal tear of the knee;

             (m) tuberculosis.
         (4)          having a partial or total knee replacement before the clinical worsening of popliteal cyst;
         (5)          for clinical worsening of a popliteal cyst manifesting as rupture of a popliteal cyst only, undertaking physical activity at a minimum intensity of five METS at the time of the clinical worsening of popliteal cyst;
Note: MET is defined in the Schedule 1 - Dictionary.
(6)          inability to obtain appropriate clinical management for popliteal cyst.
