Overview
Brief Summary
The objective of this trial is to compare the efficacy of three different nerve blocks as an analgesic option after total knee arthroplasty (TKA), based on muscle strength, mobilization and pain.
The Adductor Canal Block has been proposed as an equally effective technique to the Femoral Nerve Block in terms of pain control after a TKA, with the benefit of preserving muscle function. We hypothesize that a block performed at the apex of the femoral triangle would best balance analgesia with quadriceps function.

Outcomes
Primary Outcomes
Maximum voluntary isometric contraction (MVIC)
Time Frame: 6 hours postoperatively
It measures quadriceps strength and is normalized to the body mass index (N \* m/kg). This test correlates well with the functional outcome. Will be measured with standard handheld dynamometer (MicroFET2; Hoogan Industries, West Jordan, Utah) perpendicular to the tibial crest 5 cm proximal to the medial malleolus to make the measurement. The patients are told to "reach maximum force and hold for three seconds." Three measurements will be done, and the average will be taken. The primary effectiveness endpoints of the study will be the percentage of baselineMVIC retained on the quadriceps of the leg receiving arthroplasty for each subject at 6 hours postoperatively. A higher the percentage will relate with less motor block.
Secondary Outcomes
- Quantity of opioids administered(6, 24 and 48 hours postoperatively.)
- APS-POQ-R.(At 24 hours postoperatively)
- Pain measurement trough the visual analogue scale (VAS)(6, 24 and 48 hours postoperatively.)
- Maximum voluntary isometric contraction (MVIC)(24 and 48 hours postoperatively.)
- Timed Up and Go (TUG)(6, 24 and 48 hours postoperatively.)
- 30' CST (30 secs Chair Stand Test)(6, 24 and 48 hours postoperatively.)
- Range of Motion (ROM)(6, 24 and 48 hours postoperatively.)
- Daniels' Test(6, 24 and 48 hours postoperatively.)
- 10-PMS (10 point Mobility Scale)(6, 24 and 48 hours postoperatively.)
- Patient satisfaction(24 and 48 hours postoperatively)
- Length of hospital stay(at patient discharge, an average of 6 days postoperatively)
