Conditions

Anterior Cruciate Ligament injury

Interventions

The patient is placed in a resting back position on a platform, and an observer places an echo on the knee on the operative side for evaluation. The MRI results are collected from the electronic medic

Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: Patients who can give written consent Patients with first-time or ACL re-tear injuries Must be observable for the entire duration of the study

Exclusion criteria

Exclusion criteria: Patients who are not considered appropriate for the study by the investigator Patients with complex injuries to ligaments other than the ACL Patients with bleeding tendency or complications that may cause problems in training. Patients who cannot undergo MRI imaging (e.g., after closed body metal implantation) Patients who cannot be observed for the entire study period at the time of consent.

Design outcomes

Primary

MeasureTime frame
Evaluation of musculoskeletal muscles and non-contractile tissues around the knee joint (muscle thickness, muscle brightness) using ultrasound imaging system (echo) Knee isokinetic knee extension and flexion muscle strength (using BIODEX system4)

Secondary

MeasureTime frame
ACL Osteoarthritis Score and Ligamentization (maturity of reconstructive ligament) by magnetic resonance imaging (MRI) Knee joint function evaluation (single leg hop test) Quantitative evaluation of knee extensor and flexor muscles using surface electromyography (EM-701M2, Noraxon) Subjective, patient-oriented evaluation of the knee joint; IKDC (International Knee Documentation Committee) score, KOOS (Knee Injury and Osteoarthritis Outcome Score), Tegner Activity Scale score, Lysholm Knee Questionnaire score
