Now 9 months ago, Wietze had to have his 2nd knee operated on. Recovery was far from successful, this due to recurrent wear and tear in the operated knee. The attending physician(s) recommended that the knee be operated on again, this time for a full artificial knee. Wietze will undergo surgery on Dec. 17. During the holidays, he should take all the rest he needs to re-enter the recovery process. Wietze will not be able to make much physical effort for at least another six months, so unfortunately the crutches will remain for the time being.
