My Zada had both knees done at the same time, then months later had a torn ligament which the orthopedic surgeon found that the LP surgery was not done correctly. My poor girl spent 3 months in her crate and expen the first time and another three months the second time.
If your worried about doing house work, try putting her in a front carrier. The type that allow her back legs to dangle our maybe a sling. Take her out for walks, but carry her of course or use pet stroller. There are many ways to make sure they are comfortable, and to let you get some house work.
