Abstract
We have analysed the early functional results in patients who have had the NRG total knee replacement at the Princess Elizabeth Orthopaedic Centre, Exeter. This is a new modern design designed for high function. We analysed a total of 54 knees (47 patients) operated between September 2005 and October 2007. The follow up ranged from 9 to 25 months averaging 16 months. Thirty eight percent of the patients were male and 62% female. The age of the patients ranged from 42 to 90 (average 72).
The Oxford knee score and satisfaction score were documented at 6 weeks, 6 months, I year and 2 years. The range of movement was also noted. Ninety eight patients had the highest satisfaction score of 3 at the one year follow up. The average Oxford knee score pre-operatively was 45 and the average was 30 at 6 weeks and 6 months and 20 at 1 and 2 year follow up. Seventy four percent of the patients had post operative knee flexion of more than 100 degrees. The average post operative value added flexion was 14 degrees.
We conclude the early results of the NRG knee replacement are very encouraging with very good patient satisfaction scores and post operative flexion of the knee.
