PREOPERATIVE DIAGNOSIS: Degenerative osteoarthritis of the right knee POSTOPERATIVE DIAGNOSIS:

Question Answered step-by-step PREOPERATIVE DIAGNOSIS: Degenerative osteoarthritis of the right knee POSTOPERATIVE DIAGNOSIS: Degenerative osteoarthritis of the right knee OPERATION PERFORMED: Computer-assisted navigation right total knee arthroplasty COMPONENTS USED: Biomet Vanguard metal femur 62.5 mm PS, polyethylene tibial tray 82 mm, 10 mm PS insert ANESTHESIA: Continuous spinal epidural INDICATIONS: This is a 60-year old active patient with severe degenerative osteoarthritis of her right knee. She presents today for a right total knee arthroplasty with computer assisted navigation.DESCRIPTION OF PROCEDURE: The patient was brought to the operating room, prepped, draped and general anesthesia was administered. A midline incision was made centered over the patella and carried down to the quadriceps mechanism. Median parapatellar incision was fashioned. Subperiosteal dissection of proximal medial plateau of the posteromedial corner was accomplished. Distal femoral trackers were placed. The distal femoral tracker was navigated into position and pinned in place and confirmed. Distal femoral cut was made and verified. The 2 sizing jig was positioned in the hybrid technique for rotation and was computer navigated. The 67.5 was selected and the anterior, posterior, condylar, and chamber cuts were made. Following this, the remnants of the anterior cruciate ligament and medial and lateral menisci were excised, followed by placement of a Homén retractor to expose the proximal tibia. Anterior tibial osteophyte was resected. The tibial cut block was navigated into position and pinned in place. This was confirmed. The proximal tibial cut was made and verified. The 83 sizing plate was positioned and selected.Extramedullary alignment was used to confirm alignment and was pinned in place. Stem punch was passed. Following this, the posterior cruciate ligament was excised, posterior condylar osteophytes were resected, and posterior capsular release was accomplished. The intercondylar notch guide was placed and the notch cut was made. All components were cemented and the patella tracked well at the conclusion of the procedure. The patient was extubated and taken to recovery without any complications.ICD-10-PCS Answers: _________________________ and _____________________________ Health Science Science Nursing MC MISC Share QuestionEmailCopy link Comments (0)
