The Fall Doc #24 Why Some Knee Replacements Fail

Not every knee replacement recovery goes smoothly—and when strength and rehabilitation are neglected, the long-term consequences can be significant. In this episode of The Fall Doc, hosts Dennis Fraise and Dr. John Thompson discuss the hidden challenges that can follow knee replacement surgery, especially when patients struggle to rebuild strength and mobility after the procedure. Dr. Thompson explains why quad strength is one of the most important factors in recovery and how weakness in the legs can contribute to instability, falls, and loss of independence. The conversation also explores the cycle of deconditioning that can happen after surgery, the realities of post-operative pain, and why rehabilitation shouldn't stop once formal physical therapy ends. This episode offers practical insight into how patients can stay proactive, continue building strength, and improve long-term outcomes after knee replacement surgery.
