The purpose of this case report is to highlight the advantages of computer assisted navigation surgery (CAS) to improve the accuracy in performing Total Knee Arthroplasty (TKA) in a patient affected by Paget’s disease of the femur and secondary osteoarthrosis of knee. Paget’s disease can be associated with technical difficulties while performing knee arthroplasty because of intra and/or extra-articular deformity in either sagittal or coronal planes or both and there are published reports of sub-optimal varus or valgus placement of components by the manual technique. A 55-year-old male with monostotic Paget’s involvement of the femur with lateral femoral bowing and end stage arthrosis in the knee was managed with a primary cemented cruciate-retaining TKA using Aesculap Orthopilot 5.0 navigation system. His pre-op VAS score of 8/10 and Oxford Knee Score of 20 improved to 2/10 and 42 respectively at 1 year follow up. Knee involvement with Paget’s in Indian population is extremely rare and we are not aware of any previous case reports of using CAS in performing TKA in Paget’s. CAS can obviate the need for corrective osteotomy when performing TKA in patients with extra-articular deformity.
