李醫生在網上文章表示:TPO手術只能增加關節窩對股骨頭的覆蓋率,並無法完全解決關節鬆弛度的問題,而鬆弛度的問題才是真正導致關節持續惡化 / 脫位的最主要因素.
那麼狗狗在關節還有鬆弛的問題時,即使做完TPO手術,還是有可能會脫位嗎?
胖胖已經1歲半,3/4複診中髖關節仍有鬆弛的問題,TPO手術是否需在關節仍有鬆弛度時進行?

This is why we have to examine and evaluate each case carefully to make sure after surgery we can really enhance the centric movement of femoral head when dog is using this joint. Once this function can be achieved and the femoral head will settle into the acetabulum in 2-4 weeks after surgery. At this time, the femoral head coverage always will be more than 60%, then the chance for the eccentric movement of femoral head will be reduced and dog can have a function joint to use in the rest of their life. The TPO sugery can't 100% to make the joint back to their normal anotomic position so there is a possibility to reduce 2nd DJD of this joint(because surgery improve joint function)but can't 100% get rid of it.
