Question to the orthopod

My sister has just had a TKR can you please tell me what degree of knee movement should be expected 2 weeks after? should she expect 110 degree of movement down the track? Is an MUA common in assisting patients that are experiencing minimal movement? Will she always have pain associated with that knee? She suffered RSDS in the first TKR 9 years ago that knee is totally stuffed that was the opposite knee to this recent one. The surgeon said there was only a 2% chance of RSDS in this knee, what is your opinion? Thanks Lynsey.

hi lynsey,
POOR motivation is one of predisposing factors for RSD to develop n knee following TKR.
Now a days RSD is an obsolete term. We call it COMPLEX REGIONAL PAIN SYNDROME.
There are 100 and more reasons/ causes of RSD. But in TKR, if it happens, the main cause is what i said.

Why do you say that poor motivation ensures a high probability of RSDS, surely poor motivation has a number of causes other than RSDS, there are no other symptoms to suggest the onset of RSDS. Lynsey.

hi lynsey163,
the Range of motion depends on the type of implant you have used.Standard implamts promise about 110 degree ROM(zimmer normal knee/depur PFC) where as there are some which give about 165 degrees ROM (zimmer high flex knee / depuy rotating platform knee). so you have to tell me , which implant you have used.
2 weeks is a pretty  small time. by this time ROM should be atleast 90 degrees, no matter what implant you have used. If your physiotherapist or patient herself has poor motivation, then getting RSD will be a sure probability. So gear up for agressive physiotherapy.
Hope your question was answer properly. Feel free to ask more.
regards
