Brief summary
A pneumatic tourniquet is often used during total knee arthroplasty. However, its effect on postoperative outcomes as soft tissue damage resulting in delayed recovery remains unclear. The purpose of the present study was to compare tourniquet use versus non-tourniquet use during total knee arthroplasty for short-term functional recovery.
Detailed description
In a prospective cohort design, consecutive series of patients who underwent primary unilateral total knee arthroplasty (TKA) in the Bergman Clinic, the Netherlands were investigated. Patients scheduled for primary TKA due to osteoarthritis, age between 50 and 75 years and with Dutch language proficiency were eligible for inclusion. Exclusion criteria were inflammatory arthritis, severe cardiac complaints, severe pulmonary disorders, Body Mass Index (BMI) \>35, severe coagulation disorders or hospitalization in the previous two months before surgery. Each patient included in the study signed informed consent. The research protocol was approved by the Regional Ethics Committee VCMO in Nieuwegein, the Netherlands, registration number W13.022.
Interventions
PROCEDURETourniquet application during surgery
Both groups received usual care according to the orthopedic surgeons surgical preferences. One group received no tourniquet during surgery (non-tourniquet group) and the other group received a pneumatic tourniquet during surgery (tourniquet-group).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Knee Injury and Osteoarthritis Score (KOOS) questionnaire | 8 weeks | The KOOS questionnaire was used to assess the functional outcome. Changes were evaluated from baseline at 8 weeks. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Range of Motion (ROM) | Baseline, day 1, day 2, day 3 and 8 weeks | A standard clinical 30cm goniometer was used to evaluated the ROM |
| Isometric bilateral strength | Baseline and 8 weeks | Bilateral isometric strength of the lower limb was measured using hand-held dynamometry (HHD) |
| VAS questionnaire. | Baseline, day 1, day 2, day 3 and 8 weeks | A 100mm Visual Analogue Scale was used for measuring current, minimal and maximal pain. |
| EQ-5D questionnaire | Baseline, day 1, day 2, day 3 and 8 weeks | Quality of life was using the EQ05D questionnaire. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Length of Stay (LOS) | Baseline, day 1, day 2 and day 3 | The total length of each the patients in hospital stay was calculated and evaluated for comparison between both groups. |
| Used analgesics | Baseline, day 1, day 2 and day 3 | During the clinical phase, analgesic use was noted whereas the doses and time interval of each medication was recorded. |
