Plain English summary of protocol
Background and study aims
Medial osteoarthritis (wearing of the inside of the knee joint) can be treated with medial wedge high tibial osteotomy (HTO for short). This procedure involves cutting the tibial bone (shinbone) and introducing an opening wedge to change the angle of the knee joint and thereby shift the patient’s weight from the medial side (inside) to the lateral side (outside) of the knee. This then avoids the need for a partial or total knee replacement. As with other major knee operations, after surgery a lot of swelling can develop in and around the site of operation. This is painful, may increase the risk of surgical wound infection, and can limit a patient’s progress with mobilisation after the operation. Therefore, research is already ongoing in the field of knee replacement surgery to determine if a different type of bandaging of the affected leg after surgery may improve patient and clinical outcomes. A new method is now available which involves bandaging that compresses the leg. This may reduce pain and swelling because fluid cannot build up as easily. This study aims to find out whether compression bandaging is better than standard non-compression bandaging in terms of keeping a patient comfortable by reducing pain, swelling and enabling early mobilisation.
Who can participate?
Patients aged over 18 undergoing HTO
What does the study involve?
Participants are randomly allocated to receive either standard bandaging or 3M Coban compression bandaging. Follow-up is up to 12 weeks after surgery. Incidence of infection and deep vein thrombosis/pulmonary embolism, readmission to hospital, pain, degree of swelling of the affected leg, and knee joint function are all assessed. The main objective is to see whether 3M Coban bandaging is significantly better than standard bandaging at day 12 after surgery.
What are the possible benefits and risks of participating?
For participants in the standard bandaging group there is no direct benefit for taking part in this study. Patients will be cared for in exactly the same manner as they normally would, apart from the introduction of a few questionnaires. However, by taking part they will help to improve the management of knee osteoarthritis in the future. For participants in the 3M Coban compression bandaging group there may be benefits in terms of pain and swelling after the procedure. However, this has not yet been proven, and this study aims to assess this. There is no intended clinical benefit from taking part in this study. Patients cannot claim payments, reimbursement of expenses or any other benefits or incentives for taking part in this study. There is no personal safety risk anticipated regarding taking part in this study. Like with any invasive procedure, the osteotomy surgery carries risks such as bleeding, blood clots and infection after the operation. However, the osteotomy surgery itself is not classed as being part of this study and patients are asked to give separate written consent for the surgery itself. If they do decide to take part in the study, and their surgeon, nurse or the research team learns of important new information that might affect their desire to remain in the study, they will tell them as soon as possible. Appropriate precautions are in place to ensure medical and personal information are kept safe.

Scientific title | A multi-centre, two-arm, controlled, prospective randomized trial of 3M Coban dual-layer compression bandaging versus non-compression bandaging after high tibial osteotomy surgery |
Study acronym | ROBOT |
Study objectives | This study aims to assess if compression bandaging is better than standard non-compression bandaging in terms of keeping a patient comfortable by reducing pain, swelling and enabling early mobilisation. |
Ethics approval(s) | Wales REC 7, 06/02/2018, ref: 18/WA/0027 |
Health condition(s) or problem(s) studied | High tibial osteotomy |
Intervention | A total of 68 patients will be recruited and allocated to either standard bandaging (34 patients) or 3M Coban compression bandaging (also 34 patients); follow-up of patients will be up to 12 weeks post-surgery. Apart from clinical outcomes data, such as incidence of infection and deep vein thrombosis/pulmonary embolism, plus readmission to hospital, patient-reported outcomes will be recorded too. These include pain experienced, degree of swelling of the affected leg, and knee joint functionality. The main objective of the study is whether 3M Coban bandaging is significantly better than standard bandaging at day 12 post-surgery when measured on a visual display pain scale. |
Intervention type | Other |
Primary outcome measure | Level of operation-site related pain experienced at day 12 post-operation and average pain scores in the control and Coban arm, measured using the 10 cm visual descriptor scale (VDS) for pain; Timepoint(s): End of the study |
Secondary outcome measures | 1. Post-operative patient-reported outcome measures are recorded using Visual Display Scale pain and short form McGill pain questionnaire at 5, 12 days, and 6, 12 weeks post-surgery 2. Quality of night rest measured by Richards-Campbell Sleep Questionnaire (two consecutive nights per timepoint) prior to surgery as baseline, and 12 days and 6 weeks post-surgery 3. Degree of swelling of affected limb recorded by measurement of thigh, suprapatellar and calf girth prior to surgery as control, and 12 days, 3 weeks post-surgery 4. Knee function and quality of life measured using the Knee and Osteoarthritis Outcome Score (KOOS), Oxford Knee Score (OKS), quality of life measured with EQ-5D-5L prior to surgery as baseline, and 12 weeks post-surgery 5. Descriptive safety overview obtained by recording readmissions to theatre and/or hospital, infection of wound site , and diagnoses of pulmonary embolism or deep vein thrombosis at 30 days and 12 weeks post-surgery |
