Sample Name: Total Knee Arthoplasty - Right - 1
Description: Right total knee arthroplasty using a Biomet cemented components, 62.5-mm right cruciate-retaining femoral component, 71-mm Maxim tibial component, and 12-mm polyethylene insert with 31-mm patella. All components were cemented with Cobalt G.
(Medical Transcription Sample Report)
PREOPERATIVE DIAGNOSIS: Severe degenerative joint disease of the right knee.
POSTOPERATIVE DIAGNOSIS: Severe degenerative joint disease of the right knee.
PROCEDURE: Right total knee arthroplasty using a Biomet cemented components, 62.5-mm right cruciate-retaining femoral component, 71-mm Maxim tibial component, and 12-mm polyethylene insert with 31-mm patella. All components were cemented with Cobalt G.
ANESTHESIA: Spinal.
ESTIMATED BLOOD LOSS: Minimal.
The patient was taken to the Postanesthesia Care Unit in stable condition. The patient tolerated the procedure well.
INDICATIONS: The patient is a 51-year-old female complaining of worsening right knee pain. The patient had failed conservative measures and having difficulties with her activities of daily living as well as recurrent knee pain and swelling. The patient requested surgical intervention and need for total knee replacement.
All risks, benefits, expectations, and complications of surgery were explained to her in great detail and she signed informed consent. All risks including nerve and vessel damage, infection, and revision of surgery as well as component failure were explained to the patient and she did sign informed consent. The patient was given antibiotics preoperatively.
PROCEDURE DETAIL: The patient was taken to the operating suite and placed in supine position on the operating table. She was placed in the seated position and a spinal anesthetic was placed, which the patient tolerated well. The patient was then moved to supine position again and a well-padded tourniquet was placed on the right thigh. Right lower extremity was prepped and draped in sterile fashion. All extremities were padded prior to this.
There was severe osteoarthritis of the lateral compartment on the lateral femoral condyle as well as mild-to-moderate osteoarthritis in the medial femoral compartment as well severe osteoarthritis along the patellofemoral compartment. The medial periosteal tissue on the proximal tibia was elevated to the medial collateral ligament and medial collateral ligament was left intact throughout the entirety of the case.
At the extramedullary tibial guide, an extended cut was made adjusting for her alignment. Once this was performed, excess bone was removed. The reamer was placed along on the femoral canal, after which a 6-degree valgus distal cut was made along the distal femur. Once this was performed, the distal femoral size in 3 degrees external rotation, 62.5-mm cutting block was placed in 3 degrees external rotation with anterior and posterior cuts as well as anterior and posterior Chamfer cuts remained in the standard fashion. Excess bone was removed.
Next, the tibia was brought anterior and excised to 71 mm. It was then punched in standard fashion adjusting for appropriate rotation along the alignment of the tibia. Once this was performed, a 71-mm tibial trial was placed as well as a 62.5-mm femoral trial was placed with a 12-mm polyethylene insert.
Next, the patella was cut in the standard fashion measuring 31 mm and a patella bed was placed. The knee was taken for range of motion; had excellent flexion and extension as well as adequate varus and valgus stability. There was no loosening appreciated. There is no laxity appreciated along the posterior cruciate ligament.
The wounds were copiously irrigated with saline and antibiotics, and medial parapatellar arthrotomy was closed with #2 Vicryl. Subcutaneous tissue was approximated with #2-0 Vicryl and the skin was closed with staples. The patient was awakened from general anesthetic, transferred to the gurney, and taken into postanesthesia care unit in stable condition. The patient tolerated the procedure well.
