Re: knee hyperextension and TKR

Welcome Ann!

I am sorry to hear that you have not had much success with your knee

surgery, and are potentially facing more.

Knee replacement is no small surgery as you can imagine and you are right to

be cautious - the outcome of the surgery depends so much on what your

expectations will be, if it is to stop dislocations, then this might be

unrealistic as often the prosthesis can dislocate - it's the connecting

structures that allow for the dislocations and hypermobility, not the bones.

Having said that though, I do know that there are some here who have had

TKR, so I hope one or two of them will step forward and say hello!

I just happened to locate this when I was looking for something else.

I hope it helps you Ann.

Total knee arthroplasty in Ehlers-Danlos syndrome.

Rose PS, CA, Hungerford DS, McFarland EG.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota,

USA.

The Ehlers-Danlos syndromes (EDS) are a rare group of connective

tissue disorders characterized by severe joint hypermobility and

instability. Ten patients with 12 primary knee arthroplasties were

identified. Average age at time of surgery was 43.3 years, with

follow-up data acquired at an average of 65 months after surgery.

Primary indications for surgery were tibiofemoral or patellar

instability (n = 8) and arthritis (n = 4). Knee Society Functional

scores averaged 29.6 before surgery and 51.3 at time of interview

(P<.005). Knee Society Knee scores at time of follow-up evaluation

averaged 70. Tibiofemoral and patella stability were significantly

improved. Arthroplasty appears to be an effective option for knee

arthritis and instability in EDS patients, although results and

satisfaction are lower than that reported for conventional

arthroplasty indications.
