Study hypothesis
Added 13/08/09:
The RigidFix® system preserves graft tension gained during surgery, and leads to lower KT-1000 arthrometer side-to-side differences than the BioCryl® screw after six months of follow-up.
As of 13/08/09 this record has been extensively updated. All updates appear in the relevant field with the above update date.

Patient information sheet
Condition
Reconstructive surgery for anterior cruciate ligament (ACL) deficiency
Intervention
Patients will undergo standardised, arthroscopic ACL replacement by four-stranded hamstring tendon grafts. During surgery, participants will be randomised to transplant fixation by resorbable poly-L-lactide pins (experimental group) or poly-L-lactide/hydroxyapatite screws (control group). No other changes will apply in the treatment protocol. We will compare the residual anterior knee laxity at 3- and 6- months-follow-up between both methods.

Primary outcome measures
Added 13/08/09
Side-to-side (repaired to healthy knee) difference in anterior translation as measured by the KT-1000 arthrometer at a defined load (89 N) six months after surgery
Secondary outcome measures
Added 13/08/09:
1. Generic and disease-specific measures of quality of life evaluated by:
1.1. Lysholm scale
1.2. Tegner score
1.3. International Knee Documentation Committee evaluation form (IKDC) German translation
2. Magnetic resonance imaging morphology of transplants and devices
