Primary
| Measure | Time frame |
|---|---|
| Incidence of quadriceps motor block defined as paresis and paralysis of knee extension at hours postoperatively. Assessment of quadriceps femoris muscle strength: For motor block assessment the patient will be in supine position and the patient knee will be fully flexed and the patient will be asked to extend it. Muscle power at 6 12 24 hours Knee extension will be assessed according to 3 point scale 0 normal strength extension against gravity and against resistance 1 paresis extension against gravity but not against resistance 2 paralysis no extension possible and hip adduction will be assessed Timepoint: Incidence of quadriceps motor block defined as paresis and paralysis of knee extension at hours postoperatively.
