Descrizione dettagliata
Patients will be included on the first day after TKA surgery and randomized in two groups. Each group will receive 2 ACB with a 1 hour interval, one ACB with an active drug, Ropivacaine, and another ACB with a placebo drug, Saline.
At T0, arm ACB_active/placebo will receive the active ACB with Ropivacaine followed by the placebo ACB at T60 (60 minutes after T0).
At T0, arm ACB_placebo/active will receive the placebo ACB with Saline followed by the active ACB with Ropivacaine at T60 (60 minutes after T0).
Outcome measurements will be made at T60, 1 hour after the first ACB, and the difference in outcome between the groups will be compared.
Baseline values will be measured prior to the first ACB. Final measurements at T120 (120 minutes after the initial ACB), will determine if the differences between the groups are eliminated, since both groups then have received an active ACB.

Comparatore attivo: ACB_active/placebo
Patients will receive the first ACB with a active drug, 30 ml bolus Ropivacaine 7,5 mg/ml at T0. First outcome measurement are made one hour after the first ACB, prior to their second ACB. At T60 (60 minutes after T0), patients will receive their second ACB with the placebo drug, 30 ml bolus Saline and outcome measures performed again at T120(120 minutes after T0). The measurements for baseline and outcome will be made in following order: VAS pain score at rest - VAS pain score during active flexion of the knee - Muscle strength - TUG test - Highest VAS pain score during TUG test |

Comparatore placebo: ACB_placebo/active
Patients will receive the first ACB with placebo, 30 ml isotonic saline at T0. First outcome measurement are made one hour after the first ACB, prior to their second ACB. At T60(60 minutes after T0), patients will receive their second ACB with the ropivacaine 7,5 mg/ml 30 ml and outcome measures performed again at T120(120 minutes after T0). The measurements for baseline and outcome will be made in following order: VAS pain score at rest - VAS pain score during active flexion of the knee - Muscle strength - TUG test - Highest VAS pain score during TUG test |

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Difference between groups in muscle strength of the quadriceps femoris muscle.
Lasso di tempo: 60 minutes after first ACB (T60)
|
Muscle strength is assessed as maximum voluntary isometric contraction (MVIC) using a hand-held dynamometer.3
consecutive measurements will be made and the average used.
Results for each group will be presented as percentage of baseline values.
The primary outcome is the difference in MVIC between the groups.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Difference between groups in muscle strength of the quadriceps femoris muscle.
Lasso di tempo: 120 minutes after initial ACB (T120)
|
Same as primary outcome
|
120 minutes after initial ACB (T120)

|
VAS pain scores at rest
Lasso di tempo: 60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120)
|
Pain at rest (VAS 0-100 mm) one hour after the first and second ACB. Results will be compared between the two groups. VAS pain scores at rest will be inquired before any other outcome measurements. |
60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120)
|
|
VAS pain score during TUG test.
Lasso di tempo: 60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
Highest VAS (0-100 mm) pain score during TUG test will be inquired for each TUG test.
Results will be compared between the two groups.
|
60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
|
Timed Up and Go(TUG) test
Lasso di tempo: 60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
Time (seconds) to complete a TUG test measured one hour after the first and second ACB.
Results will be compared between the two groups.
|
60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
|
VAS pain scores during 45 degrees active flexion of the knee
Lasso di tempo: 60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
Specification of pain (VAS 0-100 mm) during 45 degrees active flexion of the knee one hour after first and second ACB.
Results will be compared between the two groups.
|
60 minutes after the initial ACB (T60) and 120 minutes after initial ACB (T120
|
|
Sub-group analysis of muscle strength and mobility acconding to baseline VAS during active flexion of the knee prior to the first block
Lasso di tempo: 60 minutes after first ACB (T60)
|
According to their specified VAS (0-100 mm) pain score during active flexion of the knee prior to the first block, patients will be divided into two groups.
Group 1 VAS 0-59 mm and group 2 with VAS 60-100 mm.
Results within the two groups will be compared: e.g is there a difference in MVIC in the subgroup of patients scoring VAS 0-59 during active knee flexion at baseline?
and is this difference larger in the subgroup of patients scoring VAS 60-100?
