Torn Meniscus, can surgery cause future problems?

I just had surgery on my right meniscus (left will be later this summer) and I am wondering if having your cartridge/meniscus repaired (or primitively described as completely reshaped) will prematurely break it down and cause future problems with the knee (like rapid degeneration). (Doctor went in for a routine tear repair but found more extensive damage and reshaped the whole thing-no weight on it for 10 days so far)
