Postoperative rehabilitation is important for early recovery and early return to society, but postoperative rehabilitation is often accompanied by pain. On the other hand, it is known that exercise therapy activates the endogenous pain inhibitory system and alleviates musculoskeletal pain.
In rehabilitation after knee replacement surgery, a continuous passive motion (CPM) device is used to gain range of motion of the knee. Although CPM is usually performed only on the operated side, it is expected that CPM can activate the endogenous pain inhibitory system by exercise therapy on the healthy side. In addition, we believe that CPM is effective in reacquiring the body image of the operated side, whose depth perception is diminished or lost after knee replacement. In this study, we will examine the pain-relieving effects of exercising the healthy side during postoperative range-of-motion training using CPM.

Treatment
Maneuver |
The usual treatment group applies CPM devise to the operated side for a range of motion training.
The intervention group also applies CPM devise to the non-operated knee and performs a range of motion training in sync with the operated side.

Comparison of VAS scores before and after CPM showed no significant intergroup differences on all measurement dates. However, there was a significant difference in values on day 14 (P<0.05). Both groups showed an increase in ROM after CPM, with significant increments observed on days 2 and 4 in the bilateral group and on day 14 in the unilateral group. There was no significant difference in values on postoperative day 14.

We enrolled patients aged >60 years who were scheduled for unilateral TKA at the university hospital. Patients were excluded based on the following criteria: severe pain or deformity of the knee on the contralateral side; chronic opioid use; diabetes mellitus; rheumatoid arthritis; necessity of anticoagulants; or impairment of cognitive function.
This study was conducted as a prospective randomized controlled trial. Participants were randomly assigned to two groups: a bilateral group that performed bilateral exercise on the affected and healthy sides, and a unilateral group that performed exercise therapy only on the affected side. Computer-generated block randomization (block size, 4, revealed to the study group at the first exercise) was used for randomization such that both groups contained equal numbers of patients. Group allocation was performed by the first author; the examiner and patients were blinded to group assignment until the CPM practice began. As the groups performed different CPM practices, the participants could not be masked to the group assignment.
No adverse events were noted.
The following patient information was collected preoperatively: age, sex, body mass index (BMI), diagnosis, Visual analogue scale (VAS) score, knee joint ROM, and Kellgren-Lawrence
classification for the operated and non-operated sides. For postoperative evaluation, the time from return to first use of rescue analgesia and the total amount of rescue analgesia during the study period were also measured. VAS scores and ROM on the operated side were measured immediately before and after CPM on postoperative days 2, 4, 7, and 14. The
10-m walk test was performed on postoperative days 7 and 14 to evaluate walking ability, The primary outcome was the difference in the VAS scores before and after CPM on postoperative day 14. The secondary outcome was the difference in the ROM before and after CPM and the 10-m walk test result on postoperative day 14.
