简要总结
Knee extension loss following an anterior cruciate ligament (ACL) reconstruction is believed to play an important role in quadriceps strength recovery. One of the main goals of the rehabilitation following ACL reconstruction is to restore knee extensor muscle strength. Deficits of more than a five-degree extension range of motion (ROM) could lead to delayed knee functionality and anterior knee pain. However, the effect of knee extension deficits in the early postoperative phase of the ACL reconstruction on knee extensor muscle strength recovery and knee functionality is not yet known.
This study aimed to investigate the difference between knee extensor muscle strength recovery and knee functionality in patients with ACL repair who had a knee extension ROM deficit (>5°) in the early postoperative period and those who did not.
详细描述
Knee range of motion deficits are significant surgical complications following an anterior cruciate ligament (ACL) reconstruction, and despite current advances in surgical techniques, knee range of motion cannot always be regained. Previous studies reported that knee range of motion (ROM) deficits play an important role in knee extensor muscle weakness and knee osteoarthritis. Thus, deficits in knee extension joint motion are more difficult to tolerate than flexion deficits. It has been reported that a five-degree decrease in the extension ROM of the affected knee compared to the healthy side can lead to secondary complications such as difficulty walking and anterior knee pain. However, the effect of knee extension deficits in the early postoperative phase of the ACL reconstruction on knee extensor muscle strength recovery and knee functionality is not yet known.
This study aimed to investigate the difference between knee extensor muscle strength recovery and knee functionality in patients with ACL repair who had a knee extension ROM deficit (>5°) in the early postoperative period and those who did not.

研究组 & 干预措施
Extension Deficit (>5 degrees)
Patients who had a knee extension ROM deficit of more than 5 degrees in the fourth week will be subject to the rehabilitation program under the supervision of the same physiotherapist 3 days a week for a period of 12 weeks. The rehabilitation program will include cold therapy, electrotherapy, and exercises focusing on improving knee functioning and restoring muscle strength. From 12 weeks to 6 months, a home exercise program will be advised to all patients equally.
干预措施: Extension Deficit (>5 degrees) (Other)
Extension Deficit (<5 degrees)
Patients who had a knee extension ROM deficit of less than 5 degrees in the fourth week will be subject to the rehabilitation program under the supervision of the same physiotherapist 3 days a week for a period of 12 weeks. The rehabilitation program will include cold therapy, electrotherapy, and exercises focusing on improving knee functioning and restoring muscle strength. From 12 weeks to 6 months, a home exercise program will be advised to all patients equally.
