Dear All,
I’m seeing a 37 year old male with a knee disarticulation. His height
is 6’1” and weight is 155. He’s very active and sails competitively.
He is always getting his prosthesis wet. Currently he’s using an Otto
Bock 3R30 titanium 4-bar with internal spring assist and a flex foot.
His residual limb is mature with very prominent condyles and is end
bearing. The socket is not ischial level and is open anteriorly to
permit entry with a leather tongue and velcro closure.
This is a perfect patient! And I haven’t fitted one of those in a
while! I’d appreciate recommendations for knee componentry for this
activity level. What endoskeletal knees are people having success
with? Which knees have a high level of function and are durable?
Also, I’d appreciate comments on socket design for the prominent
femoral condyles. I’d like to use suction using a silicone type liner
without socket lock. What suction designs are being used that would
accommodate the condyles?
Thank you for your comments.
Bill Velicky
