on the lateral cortex well proximal to the lateral
epicondyle. If found accurate by fluoroscopy
the guide pin is overreamed with an 8mm
cannulated reamer to e depth of 30mm.
The graft is then pulled into the tunnel. The
knee is cycled 5 times with moderate tension
on the graft. Fixation is performed with an
8x28mm resorbable interference screw at
20 degrees of knee flexion.
Remark:
In children with open physes the graft
can be fixed with a bone anchor or sutures alone
[10].
Postoperative Treatment
A knee brace with ROM 0-90° is used. The
patient is mobilized with 20kg partial
weightbearing for 3 weeks. Full weightbearing
as tolerated is started thereafter. Passive ROM
exercises to a maximum of 90degrees is
started thereafter immediately postoperatively.
Stationary cycling is started 6 weeks postop.
Full return to pivoting sports is between 4 and
5 months after the operation.
Conclusion
MPFL reconstruction using a strip of
quadricepstendon harvested subcutaneously in
the described technique has been found to
result in excellent clinical and cosmetical
results.Thistechniquecanalsoberecommended
for MPFL revision surgery as well as for
treatment of patella instability in children with
open growth plates.
