Enrollment: 106
Sex: ALL
Minimum age (years): 18
Maximum age (years): 50
Standard ages: ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: SUPPORTIVE_CARE

Brief summary: Anterior Cruciate Ligament ACL reconstruction can be performed under the combination of posterior lumbar plexus block plus sciatic nerve block. The investigators can have the same outcome by performing instead of posterior lumbar plexus block more peripheral nerve blocks. More specifically under the combination of sciatic nerve block plus femoral nerve block plus obturator nerve block.


Eligibility criteria: Inclusion Criteria:

* Age 18-50 years old
