Ohh my Dad has one that matches it exactly!! He's had his knee done twice.
The first time lasted 5 years, then he got a bone infection, so they pulled the replacement out, filled the knee with cement and tried to treat the infection before they put in a new banger.
Now he has had his opposite hip done, it packed it in due to the weird gait he developed because of the crap knee.
Me - I'm on my 2nd reconstruction.
We've all got crap knees.
Best wishes to your Dad Sundae Girl!!!
