Abstract:
The study has been carried out at the Emile de Vialar Clinic in Lyon (France)
The aim of that study is to analyze the feasibility of the mini invasive technique through a comparative and prospective
study uni-centric realized on two groups: “classical” and “mini-invasive” of 18 patients. The patients have been checked 6 to
8 months after the surgery. Check has been clinical, radiological and echographycal. Radiological laxity has been evaluated
for each compartment. The echographycal study analyzed the the patellar tendon and peri tendon.
All data were extracted on an Excel spreadsheet (Microsoft) and analyzed with spreadsheet tools and those of the toolbox
Statistical Toolbox (Matlab).
A radiological classification of the anterior tibial tuberosity (TTA) was established. The study highlights a correlation
between the TTA and the patellar apex.
The grafts taken by classical technique showed in every case good characteristic, against 45% of cases taken by «miniinvasive way". The earlier pain was 22 % in the "classic" group and 33% in «mini-invasive».
Data analysis showed no correlation between the earlier pain and (a) the result of “knee walking” test or (b) the thickness of
the peri- tendon. It was found a correlation between the results of «knee walking» test and the asymmetry of tabs width in
the "mini-invasive" group.
The IKDC scores: a) Subjective was virtually identical and b) Objective was 94% (or A) to the "classic" group and 81% (A
or B) to the group "mini- invasive".
This “mini- invasive" technique respects the infra- patellar branch of intern saphenous nerve in 95%. The indication of
sampling patellar graft by “mini invasive” technique is the TTA type III.
