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.

Observational
Bergman Clinic Naarden, Naarden, North Holland, Netherlands
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.

Inclusion criteria
Exclusion criteria
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).
Time frame: 8 weeks
The KOOS questionnaire was used to assess the functional outcome. Changes were evaluated from baseline at 8 weeks.
Time frame: Baseline, day 1, day 2, day 3 and 8 weeks
A standard clinical 30cm goniometer was used to evaluated the ROM
Time frame: Baseline and 8 weeks
Bilateral isometric strength of the lower limb was measured using hand-held dynamometry (HHD)
Time frame: Baseline, day 1, day 2, day 3 and 8 weeks
A 100mm Visual Analogue Scale was used for measuring current, minimal and maximal pain.
Time frame: Baseline, day 1, day 2, day 3 and 8 weeks
Quality of life was using the EQ05D questionnaire.
Time frame: 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.
Time frame: 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.
