Purpose: To retrospectively evaluate the midterm results after total knee replacement
using NexGen posterior-stabilised prosthesis. Material and method: Between
January 2004 - June 2005 we had performed 63 total knee arthroplasties in 47
patients (29 females and 18 males), with the mean age 62.3 years (range 51-76),
followed a mean period of 61 months (range 48-72). In all cases the implants were
cemented and the patella was resurfaced. The evaluation was performed according
to the Knee Society Score, Functional and Roentgenographic Scoring Systems.
Results: The mean preoperative Knee Society Score was 49 points compared with
93 points at latest follow-up. The mean postoperative maximum flexion was 120
degrees (range 110-130). There were no cases of patellar clunk, symptomatic
patellar maltracking or posterior dislocation. There was no radiographic evidence of
loosening or osteolysis and no revisions were performed or recommended for
loosening, osteolysis, instability or polythyene wear. Complications included one
knee with a late infection that required revision. Conclusion: The overall midterm
results from using this implant were good and support the ongoing use of this design.
However long-term studies will be required to confirm the durability of the implant.
