Introduction
There is still a controversial dicussion regarding the value of unicondylar knee replacement. Since 1952 this method has been used, but the publication of Insall and Aglietti (1980) with poor results kept up the discussion. During the last few years there has been a revival of unicondylar knee replacements. This is due to good long term results published in Europe und the USA. Repicci (1999) introduced minimal-invasive operation techniques.
Results
From April 2002 to June 2003 125 Preservation unicondylar knee systems with mobile bearing inlay were operated. The follow up period was from 1 year up to 2 years and 2 months.
The mean operative time was 65 min, the postoperative blood loss was always below < 500 ml. Quick mobilisation was always possible. At time of discharge (average 9 days) 95% of the patients achieved >100° knee flection.
The recorded complications are as followed: [Tab. 1]
Conclusion
With the Preservation knee system it is possible to implant an unicondylar knee in minimal invasive technique. The presented early results, show that patients recovery is remarkably quick. The mobile-bearing inlay has biomechanic advantages but it is more difficult to use with a higher learning curve.
