Brief summary
AIM: To investigate the impact of functional exercise training on postoperative functional recovery in patients with knee meniscus injuries. METHODS:A prospective randomized controlled trial (RCT) was conducted from April 2023 to September 2024, involving 96 patients with knee meniscus injuries who underwent meniscus repair interventions. Participants were randomly assigned to either the Control （CON） group (n=48) or the functional exercise training (FET) group (n=48) using a computer-generated random number table. The CON group received standard rehabilitation, while the FET group underwent functional exercise training. Clinical outcomes were evaluated at baseline, 1 month, and 6 months post-intervention, including the Lysholm score, IKDC score, VAS pain score, range of motion (ROM), serum levels of prostaglandin E2 (PGE2) and serotonin (5-HT), as well as passive 60° position sense and 60° motion sense. Postoperative complications occurring within 1 month were also recorded.
Interventions
BEHAVIORALControl （CON） group
Both groups were given arthroscopy and meniscoplasty. After operation, the control group received active knee flexion and extension exercise, ankle pump training, quadriceps muscle training and other routine rehabilitation training.
BEHAVIORALFunctional exercise training (FET) group
Patients in the observation group were supplemented with neuromuscular training on the basis of routine rehabilitation training, and received rehabilitation education before training. The patients were informed of the specific content, frequency, expected effect and importance of training in various forms such as on-site demonstration combined with publicity brochures and playing videos, so as to improve patient cooperation.

| International Society of Knee Injuries and Arthroscopy Score | up to 24 weeks | IKDC (International Knee Injury and Arthroscopy Score) is a tool used to assess knee function and symptoms and is widely used in rehabilitation assessment of knee injuries, especially in recovery monitoring after anterior cruciate ligament and meniscus injuries. The rating scale includes four main items: symptoms (pain, swelling, etc.), activity (functional limitations in daily activities), motor capacity (performance in physical activities), and function (knee stability and load-bearing capacity). The IKDC score is scored on a scale of 0 to 100, with 0 indicating complete loss of knee function and 100 indicating complete recovery and normal function of the knee. The higher the score, the better, indicating better knee function and less severe symptoms. The MCID (minimum clinically significant difference) of IKDC is usually 10 points. |
| Range of Motion | up to 24 weeks | — |
| Visual Analog Scale | up to 24 weeks | Visual analog scale (VAS) is a commonly used subjective pain assessment tool, which is widely used in clinical practice and research. It is usually scored on a scale of 0 to 10, which is explained as follows: 0: completely painless. 1 to 3 points: mild pain, does not affect daily life. Scores 4 to 6: Moderate pain that interferes with daily activities and sleep. Score 7 to 10: Severe pain that severely affects quality of life and daily functioning. MCID is usually 2 points. |
| Passive position sense | up to 24 weeks | The sensory threshold measurement method was used to measure passive position perception, motion perception and isotonic power. During the passive 60° position perception test, subjects were asked to sit and stop when they felt reaching the target Angle with an eye mask and headset. Each Angle was repeated three times. Record the error between the target Angle and the measured Angle; 10% of the maximum contraction force of the quadriceps isometric resistance was selected, and the activity Angle of the knee joint was set as the activity degree of the knee joint in the seated position. 60 was measured on a CPM machine using a motion test sensor. The subjects passively completed 60° knee flexion and extension at a constant angular speed of 1° / s. The subjects stopped the movement when they felt the joint movement or the joint position change. Three tests were conducted and the Angle of each perceived movement was recorded. |
| Lysholm Knee Scoring Scale scores | up to 24 weeks | The Lysholm Knee Scale (Lysholm Knee Scale) is a widely used assessment tool to measure the functional status and quality of life of the knee joint, especially in the assessment of recovery after knee injury and surgery. The scale quantifies knee function through eight items (such as claudication, pain, stability, etc.), with a total score ranging from 0 to 100, with higher scores indicating better knee function. The Lysholm Scale is designed to provide clinicians with an effective assessment tool to help them judge the impact of knee disease and injury. The MCID is 10 points. |
