Total condylar prosthesis, which was developed in 1974, was subsequently modified to a posterior cruciate substituting the posterior stabilized version in around 1978 for the purpose of improving stair climbing, better range of knee motion, prevention of posterior subluxation and more conforming knee kinematics. This prospective study was performed to assess the clinical and functional outcomes of standard cruciate retaining arthroplasty in primary osteoarthritis of knee. Methods: 29 patients who are diagnosed primary osteoarthritis knee underwent Cruciate retaining knee arthroplasty and followed up for a period of 2-3 years. Results: In our study patients were evaluated according to Knee society scoring system, which showed preoperatively poor grade and post operatively showed 73% excellent, 17 % good and 10% fair results with no poor results. Conclusion: We concluded from our study that cruciate retaining knee arthroplasty provides pain relief, good range of motion, deformity correction, no instability and no other complications.
