Continued procedure TKR for Patricia
The notch guide was lateralized on the femur. The notch BONE WAS REMOVED. The posterior femoral condyles were fretted.
The distal lug holes were DRILLED. The trochlear BONE WAS REMOVED. The chamfer cutting guide was placed and the anterior and posterior chamfer cuts were performed.
The femoral trial was placed and the trial liner was also placed. The knee was articulated and brought out to full extension. The knee was tight in both flexion and extension. The trials were removed and two additional mms of BONE WERE REMOVED FROM THE TIBIA. The trials were placed b ack and now the knee achieved full extension without hyperextension with excellent varus-valgus stability and balance, no mid flexion instability, easy flexion to at lest 120 degrees. There was minimal distractibility at 90 degrees of flexion and full flexion. This was felt to be the appropriate construct for the knee. The trial at this point was with the 12 mm trial.
The patella was EVERTED and measured with the thickness recorded as above. Using a freehand technique the patella was OSTEOTOMIZED (think thats making a hole in the knee cap) from the ostepchondral junction to the osteochondral junction leaving the above noed postresection thickness. The inner diameter was measured and the appropriate DRILL guide was placed. The three LUG HOLES WERE DRILLED. The trial was placed. The tissue on the undersurface of the qudriceps insertion into the patella was removed in order to PREVENT PATELLAR CLUNK. (? wow). Central tracking pertained without tendency towards lateral aift off or subluxation.
At this point, all trial componenets were removed and the knee was copiously irrigated with pulsatile lavage and thoroughly dried. CEMENT was mixed and appropirate doughy, a small amount was applied to the undersurface of the patella and pressurized into the cancellous bed. The patellar button was placed and held in place WITH A CLAMP and excess cement was removed. Cement was then applied to the proximal cut surface ofthe tibia and pressurized into the cancellous bone as well as into the keel HOLE. The tibial component was placed, fully seated and excess cement was removed. Cement was then appalied to the distral and anterior cut surfaces of the femur and pressurized into the cancellous bone. Cement was also applied to the posterior femoral condyles of the femoral component. The femoral component was slid into place, fully seated and excess cement was removed. The trial insert was placed. The knee was articulated (think this means put back together) brought out into full extension, flexed back to 90 degrees and any excess cement was removed. The knee was then held in full extension until the cement hardened. Range of motion, flexibility, stability, alignment and tracking were all verified.
The trial liner was removed. Any excess cement was removed. The tourniquet was released and hemostasis was obtained. The actual liner was dropped into place. The knee was articulated. Range of motion, flexibility, stability, alignment and tracking were all verified.
The knee was then copiously irrigated with pulsatile lavage and thoroughly dried. Bleeding points were cauterized. The fascial layer was closed with #1 vicryl in a figure of eight fashion. The subcutaneous tissue was closed with a running 2-0 vicryl stick followed by interrupted 2-0 Vicryl stick.
The skin was approximated with a running 3-0 Monocryl subcuticular stitch. Sterile dressing were applied. The anesthesia was reversed and the patient was awakened and she screamed bloody murder! haha just kidding!. The patient ws then transferred to her bed and taken to revoery in stable condition.
All needle and sponge counts were correct according to the circulating nurse.
That's it. Isn't it amazing all the cutting, excising drilling that is done. And then they do all the alignment trials, wagging our legs all around all the while our joint is completely exposed and cut open like when you cut a leg off the turkey.
No wonder we ache for a few months and it takes our bodies so long to repair/heal. There is nothing else like this operation. Very barbaric but we are so thankful it is available to us!
