Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate the sensory distribution of a LFCN-block with two different doses;Secondary Objective: Not applicable;Primary end point(s): -Difference in the percentage coverage of the incision (posterior approach) between the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml, assessed by cold sensation with an alcohol swab.;Timepoint(s) of evaluation of this end point: 1 hour post block | — |

| Measure | Time frame |
|---|---|
| Secondary end point(s): -Difference in the percentage coverage of the incision (anterolateral approach) between the side givenropivacain, 16 ml, versus the side given ropivacain, 8 ml, assessed by cold sensation with an alcohol swab. -Difference in the percentage coverage of the incision (posterior approach) between the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml, assessed by pinprick (von frey). -Difference in the percentage coverage of the incision (anterolateral approach) between the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml, assessed by pinprick (von frey). -The percentage of patients with no sensory function (VAS = 0) assessed by Maximum pain during tonic heat stimulation test on the most superior part of the incision (posterior approach) on the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml. -The percentage of patients with no sensory function (VAS = 0) assessed by Maximum pain during tonic heat stimulation test on the most inferior part of the incision (posterior approach) on the side givenropivacain, 16 ml, versus the side given ropivacain, 8 ml. -The percentage of patients with no sensory function (VAS = 0) assessed by Maximum pain during tonic heat stimulation test on the most superior part of the incision (anterolateral approach) on the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml. -The percentage of patients with no sensory function (VAS = 0) assessed by Maximum pain during tonic heat stimulation test on the most inferior part of the incision (anterolateral approach) on the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml. -Estimation of the areal of the sensory loss (including fotodocumentation) on the side given ropivacain, 16 ml, versus the side given ropivacain, 8 ml. Marked with the incicions -The difference in MVIC (maksimal voluntary isometric contraktion) of the knee joint between the side given ropivacain, 16 ml, versus t | — |
