[Q]: Question: Does drainage promote post-operative rehabilitation after bilateral total knee arthroplasties compared with nondrainage?
Answer: Suction drainage in TKA does not exhibit substantial advantages in promoting post-operative rehabilitation after unsophisticated TKA, compared with nondrainage. On the other hand, it might complicate the surgical operation, and increase the incidence of post-operative hemorrhage and retrograde infection. Thus we do not recommend suction drainage in unsophisticated TKA.
[A]:
no
