Effects of Preoperative Rehabilitation on Tendon Healing and Bone Mineral Density After ACLR

A Study on the Effect of Exercise Rehabilitation on Bone Mineral Density and Reconstruction Ligament Tendon Bone Healing After ACL Rupture

To explore the effect of preoperative exercise rehabilitation on bone mineral density, tendon bone healing, change of cartilage, and gait feature in patients with anterior cruciate ligament rupture.

Anterior Cruciate Ligament (ACL) injury is one of the most common sports injuries. It is a serious knee injury. The fracture of ACL can cause functional instability of knee joint, damage of meniscus and articular cartilage, and even induce knee osteoarthritis and other diseases. It has great influence on knee joint and even lower limb function of patients. Arthroscopic ACL reconstruction has become the first choice in clinical treatment of ACL fracture. ACL fracture can cause local knee joint osteoporosis, and reconstruction surgery can also affect tendon bone healing, bone canal enlargement, rehabilitation period, gait, articular cartilage degradation, etc. This study intends to conduct preoperative rehabilitation intervention for young people with anterior fork rupture, and explore the effects of exercise rehabilitation on knee bone mineral density, muscle strength, proprioceptive ability and other aspects after ACL rupture, as well as the effects of knee bone mineral density, tendon bone healing, bone tunnel aperture, motor function, gait characteristics and cartilage degradation after reconstruction.

Before ACL reconstruction,40 minutes of rehabilitation training was performed 3 times a week for 6 weeks, and gotted regular treatment. The ACL reconstruction was followed by a 0.5 year rehabilitation.

Regular rehabilitation training was not performed before ACL reconstruction, got regular treatment. The ACL reconstruction was followed by a 0.5 year rehabilitation.

Three-dimensional gait analysis system and plantar pressure were used during walking, running, cutting and jumping

Exclusion Criteria: Be older than 40 years, or less than 18 years old Within 8 weeks of the onset of the trauma, or more than 1 year Severe injury to other knee ligaments History of knee trauma
