Overview
The primary objective of this clinical trial is to verify the superiority of a digital diagnosis and treatment system for the conservative management of knee sports injuries-based on wearable sensors, machine vision, and large language models-over conventional off-site rehabilitation in terms of functional outcomes. The secondary objectives include assessing safety and adverse events, compliance and feasibility, algorithm evaluation accuracy and usability, and generating clinical evidence to support the registration of a Class II medical device. Participants will undergo a six-month intervention comprising knee muscle strengthening exercises, lower limb balance and stability training, and stretching exercises. Follow-up assessments will be conducted every four weeks, recording IKDC and Lysholm subjective knee function scores, VAS pain scores, SF-36 quality of life scores, knee range of motion, and MRI findings.
Interventions
- Other Muscle Strength Training
Wall Squats, Glute Bridges, Lunges, Crab Walks, Bulgarian Split Squats, Deadlifts, and similar exercises. - Other Lower limb balance and stability exercises
Single-leg balance stance, step-up/step-down, lower limb Y-balance single-leg stance training, lower limb single-leg stance star excursion balance training, quadruped position support, and similar exercises. - Other Stretching and Relaxation
After each training session, you can perform muscle stretching or use methods such as resistance band exercises or foam roller rolling for muscle relaxation.
Primary outcome measures
- International Knee Documentation Committee Subjective Knee Form Score [Time frame: week0、week4、week8、week12、week24]
- Lysholm Knee Scoring Scale [Time frame: week0、week4、week8、week12、week24]
Secondary outcome measures (4)
- Visual Analogue Scale [Time frame: week0、week4、week8、week12、week24]
- 36-Item Short Form Health Survey [Time frame: week0、week4、week8、week12、week24]
- Knee Range of Motion [Time frame: week0、week4、week8、week12、week24]
- Knee MRI [Time frame: week0、week4、week12、week24]
Eligibility criteria
Inclusion criteria
- Age 18-50 years.
- Clinical symptoms, signs, and MRI diagnosis confirming ACL rupture.
- First-time unilateral ACL rupture.

- Initially, unilateral knee presents with dull pain, soreness, or a sense of weakness, followed by increased knee pain predominantly located behind the patella. Pain worsens after exertion, with difficulty climbing up or down stairs, and alleviates or disappears after rest. The pain VAS score is ≤6 points.
- Positive unilateral knee patellar grind test and/or positive patellar compression test and/or positive squat test.
