Abstract: Continuous passive motion (CPM) may have potential application as a physical modality in decreasing acute pain. The purpose of this study was to examine the effects of CPM immediately following an arthroscopically-assisted anterior cruciate ligament (ACL) reconstruction utilizing bone-patella- bone autograft on acute pain during the inflammatory phase of soft tissue healing. Acute pain was measured by assessing the amount of pain medication (amount of narcotic delivered from the patient-controlled analgesia (PCA) pump during the first postoperative 24 hours and the total intake of oral medication during the second and third postoperative days), the need for pain medication (number of times the patient pushed the PCA button during the first postoperative 24 hours), and perceived pain (graphic pain scale measuring antalgic sensation). Thirty patients (15-45 years old) participated in this study. The patients were prospectively randomized into two groups, CPM and non-CPM. Both groups followed an identical postoperative rehabilitation program except for the CPM groups using a CPM device. The design of this study included the collection of data during the inflammatory phase of soft tissue healing. The results indicated that the initiation of CPM immediately following an ACL reconstruction had a significant (p < .05) effect on decreasing the amount of medication consumed by the patient and a significant (p < .05) decrease in the patient's need for medication during the inflammatory phase. There was no statistical significance in the level of perceived pain between the groups.(ABSTRACT TRUNCATED AT 250 WORDS)
