The investigators aims to evaluate the effect of multicomponent supervised tele-rehabilitation, compared to home-based self-rehabilitation, on range of motion (ROM), pain, muscle strength, and function in patients following ACLR. The hypothesis is of superiority for the effects of multicomponent supervised tele-rehabilitation over home-based self-rehabilitation.

The whole program is constituted of preoperative education and postoperative rehabilitation (in hospital and out of hospital). All the participants received the same preoperative education through the mobile phone application and oral communication. Participants in the intervention group get the multicomponent supervised tele-rehabilitation, while participants in the control group get the home-based self-rehabilitation. All the postoperative rehabilitation programs are presented and executed through the mobile phone application.
the percentage of patients who achieve a satisfactory active ROM (flexion and extension)
In the first 3 months after ACLR, the achievement of acceptable knee active extension and flexion was regarded as what matters most for a successful recovery. A good knee active ROM could guarantee an expectedly continue improvement.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
active and passive ROM
The active and passive ROM of the affected side knee
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
Visual analogue scale (VAS)
The postoperative pain was measured with VAS. The VAS scale ranges from 0 to 10 points, 0 points represent no pain, while 10 points represent the worst imaginable pain. A higher VAS score mean a worse outcome.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
Muscle strength
The isokinetic concentric strength test was used to assess muscle strength. Isokinetic concentric extenso was the best rated with sufficient intrarater reliability and construct validity for the measurement of knee muscle strength
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
The 2000 International Knee Documentation Committee (IKDC)
The 2000 International Knee Documentation Committee (IKDC) Subjective Knee Form is a patient-oriented questionnaire that assesses symptoms and function in daily living activities. Scores are obtained by summing the individual items and then transforming the crude total to a scaled number that ranges from 0 to 100. This final number is interpreted as a measure of function with higher scores representing higher levels of function.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR

knee injury and osteoarthritis outcome score (KOOS)
The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL).Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
the Tegner activity scale
the Tegner activity scale is a one-item questionnaire that is scored on an 11-item scale (0 to 10) based on the patient's reported level of activity/work. A level of 0 represents maximum disability while a level of 10 represents elite sports athletes.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
the Lysholm knee scoring scale
The Lysholm Knee Score is a questionnaire consisting of 8 items that the patient completes together with the therapist. The questionnaire is designed to assess the degree of knee instability at both impairment and limitation levels. .The Lysholm Knee Score calculates and grades an overall score from 0 to 100 based on 8 domains: squatting, locking, pain, stair climbing, support, instability, and edema.A higher score mean a better outcome. Scores between 95 and 100 are regarded as exceptional, 84 and 94 as acceptable, 65 to 83 as fair, and less than 65 as poor.
Time frame: at the 2, 4, 8, 12 and 24 weeks following the ACLR
