Which factors
can explain
these differences ?
RTP
FUNCTIONAL STABILITY
ROTATIONAL STABILITY
pivot shift
?
OSTEOARTHRITIS
Recent studies correlate residual rotatory instability
with decreased patient satisfaction , increase functional
instability , chondromalacia and the development of
osteoarthritis . . .
Ayeni Tanaka
positive pivot sign after ACL reconstruction is prognostic
of o/a in the future . . .
Jonsson
restoring rotational kinematics during dynamic pivoting
activities after ACL reconstruction is predictive of
functional outcome . . .
Zampeli , Pappas , Giotis , Hantes , Georgoulis 2012
But . . .
ACL reconstruction , with graft either hamstrings
or BTB , and with the recent techniques , can not
restore the rotation of the tibia to the previous
physiological levels during activities with
increased rotational loading of the knee ,
although the abnormal anteroposterior tanslation
of the tibia has been restablished
Prof An. Georgoulis
Improved
techniques
?
“ posterolateralization ” ?
a more horizontal placement of the femoral
tunnel ,close to 10 o΄clock , which is
anatomically closer to the insertion of the p/l
bundle , can improve rotational stability , without
full restoration
Lucchetti
Double – bundle technique ?
the anatomical double-bundle
reconstruction can decrease the translation and
rotation of the tibia during pivot-shift
Zaffagnini
there are no studies showing any major clinical
advantages in terms of using the double-bundle
surgical technique
Meredick , Sammuelson
technically demanding
dependent on individual anatomical factors
revision ?
Lateral tenodesis ?
. . . The addition of a lateral extra-articular
reconstruction to a standard single bundle ACL
reconstruction with hamstrings tendons graft , is more
effective in reducing the IR of the tibia at 30o of knee
flexion , as compared with a standard single bundle
ACL reconstruction and with an anatomic double
bundle reconstruction . . .
Monaco 2007
Results
Isolated extra-articular tenodesis : only 50% of
patients reported good to excellent results
is no longer recommended
ACL reconstruction and extra-articular tenodesis :
80-90% good to excellent results

In summary our EARLY results showed :
Improved stability ( mainly in the last degrees of extension )
and protection of the knee
Without elongation of the recovery time
Slight delay in achieving full ROM
Without any special demands
Particularly for athletes with high
demanding pivot and cutting activities (
such as footballers ) , the addition of
lateral tenodesis provides a more stable
knee and offers an unrestricted return to
