Knee Hyperextension After TKR

Posted by brendaem @brendaem, May 18, 2023

Has anyone who has had TKR experienced a problem with backwards hyperextension of the joint? I had TKR in October 2019. My recovery has been complicated by a sacroiliac joint issue with radiculopathy that has responded to injections and LOTS of PT. However, my knee continues to hyperextend. My ortho X-rays are normal, and the surgeon says sometimes it takes a year, 18 months, 2 years to fully recover. It’s been 3.5 years now and they’re telling me that maybe I need different hardware in the knee. Maybe?? I don’t want another surgery based on a maybe! Has anyone else had to deal with this?

I saw an ortho last year for second opinion on knee. I am pretty worried. I had atrophy of my quad after TKR in 2020. I could not climb stairs, said it was due to quad shut down, etc But, over the course of 4 years, the hyper extension started. From what I understand, this typically is rare. Saw a neurologist. First thought femoral neuropathy. Year later 2022, saw another neurologist- EMG, had an abnormal EMG. Fast forward- 2023- neuromuscular did EMG, she said normal.

Saw ortho revisionist- aspirated knee, thinks- I have an infection. Waiting more tests in next 2 weeks.

Now, my other knee needs replacement .

I had total left knee replacement in Sept, 2023...it was a very difficult and painful recovery
I had total right knee replacement in March, 2024. That went better...I noticed that the first surgery, left knee, continued to be more painful and swollen.
Shortly thereafter my left knee was bowing backwards, called
Hyper flexing. I am still in PT and they had not seen a case like mine.
I returned to the surgeon yesterday and he said in all of his years he had not had a case like mine.
He said 3 options ...remove the device and replace it with a henge type of appliance or put in a "plastic wedge" or a full leg brace.
I am not up for another surgery. I am so disappointed...I also have other health issues.
Has anyone ever experienced hyper flexing and what was done about it? I will appreciate your input as I limp along!

Hello. I am having an issue with hypertension also after 3 acl surgeries. And a total knee replacement in March. My original injury was May 2020 physical therapy after each surgery. Then a whole year of therapy that I’ve just finished. The physical therapist and my surgeon say they have never seen this issue before. I’m feeling defeated As I haven’t walked correctly in almost 5 years.

Yes, this happens to me. My TKR on my right knee was 7/2024. I am back to walking on average 7,500 steps/day, and most mornings I walk about 3 miles for exercise. The hyperflexing happens once every 1-2 days...scares me because it comes out of nowhere...it doesn't hurt, and once it happens all is good again. My PT believed it' because the muscles aroung my knee aren't strong enough yet...maybe?
