Ropivacaine
30 mL Ropivacaine 0,75% administered as a unilateral TQL block
Quadriceps muscle strength
Quadriceps muscle strength is assessed using a hand-held dynamometer. Each participant is tested pre block administration and 60 minutes after
Timed Up and Go
To test mobilisation the standardised Timed Up and Go test is used. Each participant is tested pre block administration and 60 minutes after
Single-leg 6 meter timed hop test
To test muscle strength and power the single-leg 6 meter jump test is used. Each participant is tested pre block administration and 60 minutes after
Temperature discrimination
Dermatomal evaluation of cold and warm discrimination of the thoracic and lumbar dermatomes Approximately 60 minutes after block administration
Pinprick test
"Dermatomal evaluation of pinprick/sharp sensation of the thoracic and lumbar dermatomes.~Approximately 60 minutes after block administration"
Blood samples
As a substudy the maximum serum concentration of ropivacaine is analyzed. Blood samples are taken at 0, 15, 30, 45 and 60 minutes after block administration
Non-invasive blood pressure measurement
Non-invasive blood pressure is measured prior to block administration and 30 minutes after block administration
