Pain management medication regime was with no help as well. The pain has worsened over the past 1 year with no particular onset or event that could cause the pain scale of 8/10, this caused the patient to undergo a sequence of cortisone injections which provided relief for just 3 weeks.

Right knee was draped and prepped using sterilization precautions. A straight incision was placed over the knee joint after exsanguinating the extremity. Skin and subcutaneous tissues were incised. Medial parapatellar arthrotomy was performed. Attention was then turned towards the femur. The distal femoral resection guide was placed into position. The distal femoral resection guide was placed into position. The distal resection was made, The anterior, posterior chamfer and oblique cuts were then made using the resection guide. Attention was then turned towards the tibia. The tibial resection was performed. The alignments were checked with the knee extended. The patella was everted. Patellar resection was performed. Drill holes were made in the patella. Trial patella was then placed into position.
