Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Identifying the optimal anesthesia technique for patients undergoing total knee arthroplasty according to the fast track protocol giving the best functional outcome;Secondary Objective: Identifying the optimal anesthesia technique for patients undergoing total knee arthroplasty according to the fast track protocol in terms of: pain, used pain medication, quality, quantity and safety of in-hospital mobilization, patient satisfaction, time to reach discharge criteria, length of stay, patient reported functional outcome and quality of life. ;Primary end point(s): Functional outcome will be measured with a performance battery consisting of three functional tests: the Timed-Up-And-Go test, the Stair Climbing Task and the Six Minute Walk test.;Timepoint(s) of evaluation of this end point: The performance battery will be done pre-operative, at reaching hospital discharge criteria, 3 months post-operative and one year post-operative | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): NRS pain, used pain medication, quality of in-hospital mobilization by NRS given by the physical therapist, quantity of in-hospital mobilization measured with an accelerometer and safety of in-hospital mobilization by NRS given by the physical therapist, patient satisfaction with the analgesia (NRS), time to reach discharge criteria in days, length of stay in days, patient reported functional outcome using LEFS and Oxford12Q questionnaires and quality of life using the EQ5D questionnaire. ;Timepoint(s) of evaluation of this end point: Pre-operative, at reaching hospital discharge criteria, 6 weeks post-operative, 3 months post-operative and one year post-operative | — |
