Abstract
Background: Knee Arthritis in most patients begins and remains confined to medial compartment. Unicondylar knee replacement (UKR) can be better alternative in these selected patients. Methods: Eighty one consecutive unicondylar knee arthroplasties in 60 patients of isolated medial compartment arthritis were done using Allegrato unicondylar knee. Patients were followed up at 6month interval with average follow up 1.8 yrs. Knee society score was used for comparative evaluation of these patients. Results: The mean pre operative knee society score of 62 improved to post op. score of 94. No complication reported so far except one case of tibial base plate dislocation requiring re fixation. Our short-term results are good to excellent with 100 % survival at avg. follow up of 1.8 years. Conclusion: UKA is better alternative with many advantages in selected patients of early symptomatic medial compartment arthritis. However proper patient selection improvised design, exacting surgical technique and experienced team with established center are must for uncompromising results.
