Introduction
Minimally invasive unicompartmental knee
replacement surgery is now very popular. It
is therefore important to know if this is safe
and effective. The aim of this study was to
determine the midterm results of the Oxford
unicompartmental knee implanted with a
minimally invasive approach.
Materials and Methods
This prospective study reports the complications
and survival of the fi rst 688 Phase
3 minimally invasive Oxford medial UKR
implanted by two surgeons and followed up
independently. None were lost to follow-up.
One hundred and thirty two of the replacements
were implanted over fi ve years ago.
The clinical assessment of 101 of these that
were available for review at fi ve years is also
presented.
Results
Nine of the 688 knees were revised: four
for infection, three for bearing dislocation
and two for unexplained pain. The survival
rate at seven years was 97.3% (CI: 5.3 %),
in addition seven knees (1%) required other
procedures: four MUAs, two arthroscopies
and one debridement for superfi cial infection.
At fi ve years, 96% of patients had a good or
excellent Knee Society rating, their average
Oxford knee score (OKS) was 39 and their
average fl exion was 133 0.
Conclusions
This study demonstrates that the minimally
invasive Oxford UKR is a reliable and effective
procedure.

Background:
Unicompartmental knee arthroplasty is experiencing
a resurgence in popularity worldwide.
The purpose of this study was to report our
experience with the Miller-Galante unicompartmental
knee arthroplasty at a mean 10
year follow-up in order to determine if this
procedure can provide durable long-term
clinical results.
Methods:
The study group consisted of 109 consecutive
Miller-Galante unicompartmental knee
arthroplasties in 83 patients performed by
two surgeons between 1989 and 1997. There
were 107 medial and two lateral compartment
arthroplasties performed. The mean age of
