Outcome measures
Primary outcome
The main study parameter is hamstring muscle strength deficit. Measured by a
Biodex dynamometer.
Secondary outcome
Not applicable
Background summary
Anterior cruciate ligament (ACL) reconstruction techniques are developing
continuously. Studies have shown that anatomical positioning of the femur
tunnel is an important predictor for the clinical outcome. This has led to the
development of new reconstruction techniques with a more anatomical placement
of the femur tunnel: the anteromedial portal (AMP) ACL reconstruction technique
and, more recently, the tape locking screw (TLS) ACL reconstruction technique.
Multiple retrospective studies have shown that the use of a the anteromedial
portal (AMP) and tape locking crew (TLS) reconstruction technique have a better
short term clinical outcome. At this moment, the most widely used technique is
the AMP (performed in approximately 80% of the ACL reconstructions). The TLS
technique is widely used in France and the available literature shows good
short-term results.
A difference between the AMP and the TLS techniques is that the AMP technique
uses a double-bundle hamstring graft where the TLS technique uses a
single-bundle hamstring graft. The idea is that using a single-bundle hamstring
graft causes a less hamstring muscle strength deficit. The available literature
shows different outcomes of hamstring muscle strength deficit, although, there
are no studies found in which the difference in hamstring muscle strength
deficit between both techniques directly has been investigated.
Study objective
The main objective of this study is to compare the hamstring muscle strength
deficit after AMP and TLS reconstruction techniques.
Study design
Retrospective case-controlled pilot study
Study burden and risks
Both intervention operation procedures which are performed are considered safe
and effective. The burden for the participants in this study is limited. The
follow-up after ACL reconstructive surgery is standardized in our hospital. The
participants of this study will undergo the same standardized follow-up. The
patient will undergo an additional biodex measurement 12 and 20 weeks after
surgery which wil take approximately 45 minutes. There are no risks to the
Biodex measurement for the patient. It is a non-invasive test.
