Brief summary
The goal of this randomized clinical trial is to investigate the postoperative recovery following hip and knee arthroplasty procedures depending on the use of either spinal anaesthesia (SA) or general anaesthesia (GA). The main questions are: * Are more patients able to be safely mobilized within 6 hours postoperatively when using GA compared to SA? * Does postoperative pain, nausea and vomiting, dizzyness, occurence of delirium and urinary retention differ between the anaesthetic methods? Participants, scheduled for total hip, total knee and unicomartmental knee arthroplasty, will be randomized to recieve spinal anaesthesia or general anaesthesia in relation to surgery. At 6 hours postoperatively a physiotherapist will conduct a 5-meter walking test to evaluate whether the participant can be safely mobilized.
Interventions
plain or heavy Bupivacaine hydrochloride 10 mg (2 mL) injected in the spinal canal
Propofol (induction: 1.0-2.0 mg/kg. infusion: 3-5 mg/kg/hour) + Remifentanil (induction: 3-5 mcg/kg, infusion: 0.5 mcg/kg/min) given intravenously

Study design
Masking description
Physcians and nurses in the surgical department are not able to be blinded. But outcome assesors (ie. physiotherapists, research personel) are not aware of the treatment allocation.
Intervention model description
Each of the three arthroplasty procedures are investigated in a 2-arm randomised trial: Total hip arthroplasty - either spinal anaesthesia or general anaesthesia. Total knee arthroplasty - either spinal anaesthesia or general anaesthesia. Unicompartmental knee arthroplasty - either spinal anaesthesia or general anaesthesia.
Eligibility
Inclusion criteria
* Clinical and radiological hip or knee osteoarthritis meeting the indications for primary total hip, total knee, or unicompartmental knee arthroplasty. * ≥18 years of age. * Able to speak and understand Danish * Able to give informed consent and must be cognitively intact.
Exclusion criteria
* Lives in an institution. * Uses walking aid such as a walker or a wheelchair. * Terminal illness. * Has contraindications for either general or spinal anaesthesia. * Has objections to receiving either general or spinal anaesthesia. * Requires anxiolytics as premedication prior to anaesthesia. * Traumatic aetiology as a basis for surgical indication. * Altered pain perception and / or neurologic affection due to diabetes or other disorders. * Daily preoperative use of opioids \> 30 mg of morphine milligram equivalents (MME). * Standard primary arthroplasty procedure is evaluated not to be suitable. * Women considered fertile but without sufficient birth control.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ability to be mobilsed safely within 6 hours of surgery | within 6 hours postoperatively. | 5-meter walking test where a physiotherapist evaluates whether the participant can be safely mobilized within 6 hours of surgery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain score | On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted. | Will be recorded during rest and 5-m walk using participant evaluated NRS of 0 to 10, with 10 being worst pain/dizziness/nausea imaginable. This will be recorded at 4 and 6 hours post-operatively on the day of surgery and at 10:00 and 18:00 on the following postoperative days. |
| Fulfilment of discharge criteria | On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted. | Dichotomous (Yes or No) |
| Opioid use in Morphine Milligram Equivilents within the first 6 hours of surgery | On the day of surgery: Within the first 6 hours after surgery. | Cumulated opioid use in Morphine Milligram Equivalents. |
| Nausea Score | On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted. | Will be recorded during rest and 5-m walk using participant evaluated NRS of 0 to 10, with 10 being worst pain/dizziness/nausea imaginable. This will be recorded at 4 and 6 hours post-operatively on the day of surgery and at 10:00 and 18:00 on the following postoperative days. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Quality of Recovery-15 score | On the day of surgery: at 4 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00. This will be asses as long as the patient is admitted. | Four hours postoperatively on the day of surgery and at 10:00 on the following |
| Vital signs - diastolic blood pressure | On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted. | Diastolic blood pressure (mmHg). |
| Vital signs - systolic blood pressure | On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted. | Systolic blood pressure (mmHg). |
