The purpose of the study is to find the best way to mobilize a knee after total knee arthroplasty (TKA). In particular, the aim of this study will be to investigate the advantages of adding a gentle knee mobilization to the standard rehabilitation used by physiotherapists in this hospital after TKA.
All individuals waiting for TKA from the "Departement de l'appareill Locomoteur (DAL) - Centre Hospitalier Universitaire Vaudoise (CHUV)" will be considered for this research trial. The number of individuals necessary to complete this study is 32.
Participants deciding to take part will be given an information sheet and asked to sign a consent form. If deciding to take part, they will still be free to withdraw at any time and without giving a reason. A decision to withdraw at any time, or a decision not to take part, will not affect the standard of care they receive.
People who agree to take part will be randomly selected into 2 groups: one group will follow the standard treatment used in physiotherapy after TKA, the other group will have the same treatment and the technique of A+ mobilization in investigation added. Participants have 50% chances to be allocated to either of the groups. Before surgery, at the first and seventh day after operation, the researchers will measure the range of motion (ROM) of the replaced knee. This means that the study will last till the moment the last participant leaves the DAL - CHUV, which is estimated to be in 12 months after the first recruitment.
Individuals over 18 years old undergoing unilateral primary TKA caused by osteoarthritis will included. Exclusion criteria will be: a) insufficient French language skills to agree a written consent, b) body mass index (BMI) >40 kg/m2, c) symptomatic OA in the contralateral knee (defined as self-reported knee pain >4 on a 10-point verbal analogue scale), d) other lower extremity orthopedic problems limiting function, e) neurologic impairment or g) cognitive dysfunction.
No life-style restrictions will be requested. Patients will just need to follow the physiotherapist's usual advices during the in-hospital period at the DAL - CHUV. This study does not alter the standard procedures, patients will receive all the techniques used in physiotherapy as every other TKA patient. If allocated into the mobilization group, a specific knee splint will be positioned on the patient's knee. This position will be held for 20 minutes with the leg straight and 20 minutes bent, twice a day. The person in charge of these procedures is the principal investigator of the study, a certified orthopedic physiotherapist on the staff of the DAL - CHUV. No additional changes to patients' daily routine will be involved.
To the investigators knowledge, there are no side effects due to use of this mobilization. Nevertheless, the pain levels of every patient will be recorded to identify any differences between groups. If, during or after the clinical study, any patient will face unexpected health problems related with the study, they will be kindly asked to transmit the information to the principal investigator of the study. The mobilization technique involves no additional risk over that of standard treatment performed in the hospital. This study hypothesis that adding A+ graded mobilization combined with the standard in-hospital rehabilitation protocol will improve ROM without increasing pain.
All information collected will be kept strictly confidential. Any information used will have names and addresses removed. All data will be stored, analyzed and reported in compliance with the Data Protection Legislation of Switzerland.
