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.

Arm Intervention/treatment
Active Comparator: Femoral Nerve Block
Ultrasound guided femoral nerve block, 30 ml of 0.25% bupivacaine and 4 mg of dexamethasone to be administered.
Procedure: Femoral Nerve Block
Regional anesthetic technique that blocks the sensory and motor information of the femoral nerve (and it's branches).

Active Comparator: Adductor Canal Block
Ultrasound guided adductor canal block, at the proximal third of the canal, 30 ml of 0.25% bupivacaine and 4 mg of dexamethasone to be administered.
Procedure: Adductor Canal Block
Interfascial block that targets mainly the saphenous nerve.

Experimental: Apex Femoral Triangle Block
Ultrasound guided femoral triangle block, at the distal third of the triangle, 30 ml of 0.25% bupivacaine and 4 mg of dexamethasone to be administered.
Procedure: Apex Femoral Triangle Block
Nerve block that aims the vastus medialis nerve, the saphenous nerve and the anterior femoral cutaneous nerve.




Primary Outcome Measures :
  1. 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 Outcome Measures :
  1. Timed Up and Go (TUG) [ Time Frame: 6, 24 and 48 hours postoperatively. ]

    Timed Up and Go gauges a patient's sense of balance by measuring the time required for a certain set of movements: stand up from a chair, walk 3 m, walk back, and sit down. It has been verified to serve as a good indicator of functional level.

    Measured in seconds, the better values are related to shorter times.


  2. 30' CST (30 secs Chair Stand Test) [ Time Frame: 6, 24 and 48 hours postoperatively. ]
    How many times can a patient stand up and sit down from a chair in 30 seconds. The amount of times will be counted, more times will be related to a better outcome.

  3. Range of Motion (ROM) [ Time Frame: 6, 24 and 48 hours postoperatively. ]
    Range of motion refers to a knee's degree of extension or flexion and is measured via a goniometer. Considering normal values from 0-120º, the baseline movement will be measured preoperatively to be compared postoperatively.

  4. Daniels' Test [ Time Frame: 6, 24 and 48 hours postoperatively. ]
    Active extension of the knee against gravity and applied resistance (0-5). 5: normal contraction against gravity and maximal resistance. 0: abscence of contraction.

  5. 10-PMS (10 point Mobility Scale) [ Time Frame: 6, 24 and 48 hours postoperatively. ]

    Scale from 0-10 in which the mobility of the patient is measured; sitting on the bed, chair, edge of the bed, mobilize the knee more than 45º, stand up, walk with or without a mobility aid.

    Higher values are related to better outcomes.

    An expected degree of flexion of the knee is ≥45 degrees on postoperative day 1 and ≥70 degrees on postoperative day 3.

    Expected points for postoperative day 0: 4 points Expected points for postoperative day 1: 8 points Expected points for postoperative day 2: 9-10 points


  6. Pain measurement trough the visual analogue scale (VAS) [ Time Frame: 6, 24 and 48 hours postoperatively. ]

    Pain will be measured via the VAS pain score by having the patient point on an unmarked scale how their pain was and then translating it to millimeters on the 100-mm scale.

    0 mm: no pain 100 mm: severe/extreme pain


  7. Quantity of opioids administered [ Time Frame: 6, 24 and 48 hours postoperatively. ]
    into morphine equivalent if needed.

  8. APS-POQ-R. [ Time Frame: At 24 hours postoperatively ]
    Developed by an interdisciplinary task force of members of the American Pain Society, the Patient Outcome Questionnaire (APS-POQ) for QI has been revised to include instrument psychometrics. The article is available by open access at The Journal of Pain web site.

  9. Patient satisfaction [ Time Frame: 24 and 48 hours postoperatively ]
    Scale from 0 to 10, answering how do they feel about the treatment received, being 10 the maximum value related to the highest satisfaction level.

  10. Length of hospital stay [ Time Frame: at patient discharge, an average of 6 days postoperatively ]
    Days from surgery until discharge.

  11. Maximum voluntary isometric contraction (MVIC) [ Time Frame: 24 and 48 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, 24, and 48 hours postoperatively.

    A higher the percentage will relate with less motor block.
