Background: The purpose of this case study is to present three cases in which the robotic assisted TKA device was used to correct a severe post traumatic osteoarthritis. Routine conventional TKA in complex PTOA can be challenging and difficult to execute precisely due to articular distorted anatomy.

Patients and Methods: A single centre retrospective series collated the records of three patients (mean age, 46.3 years) who underwent TKR for post-traumatic osteoarthritis of the knee associated with intra-articular malunion. Mean trauma-to-TKR interval was 8.2 years (range 1 to 6.9 years). Patients were assessed clinically and radiologically at last follow-up, using the Knee Society score and WOMAC score at a mean of 16.3 months.

Results: At a mean overall follow-up of 16.3 months (range 12 to 19 months), mean knee society score improved from 67 to 144.3 and WOMAC score 53.6 to 4.6. Mean flexion gain was 6◦: mean preoperative flexion, 103◦ (0◦ to 110◦), vs. 115◦ (0◦ to 115◦) at final follow-up. No complications were observed in this series.

Conclusion: Robot-assisted surgery allows the surgeon to restore alignment even in patients with severe deformities. In this case series, we have illustrated how the robotic device corrected severe PTOA and flexion deformities in patients, which can be challenging in routine TKA.
