Neuromuscular Training on Lower Extremity in Post-operative Anterior Cruciate Ligament Reconstruction

The knee joint problems and injuries has been rising as a result of more number of patients getting injuries in various daily livings e.g traffic and industrial accidents Ligamentous injuries are one of the commonest injuries of knee among which occurrence of Anterior cruciate ligament(ACL) injuries are of considerable importance The ACL is actually made up of many bundles of connective tissue and it has course from femur to tibia as shown in picture. The ACL is main ligament which prevents tibia to go outwards and excessive loads. When knee is in straight position ACL has 32mm length and 7-12mm width.ACL has 2 parts anteromedial bundle and posterolateral bundle. During flex position AMB goes into lengthened position and PLB goes into shorten position. It is made up of collagen fibres and its framework has proteins, glycoproteins, elastic systems, and glycoseminoglycans. Because of its elastic property it undergoes into many stresses. And it has nerve supply of tibial nerve and it has arterial supply of middle genicular artery. The Occurrence of ACL injures mostly reported among paediatric and adolescent population as compared to adult population. This factor which raises the contribution of adults to participate in sports are younger age high performance training, awareness of injury and use of better modalities. Short term complications of ACL that include loss of function, pain and reconstructive surgery period of about 24 to 36 weeks required for return to function. Reconstructive surgeries include autogenous or allogeneic graft reconstruction Many studies showed that after reconstructive surgery patients return to sports. Most (82%) patients are able to return to sport activity according to a meta-analysis results; however preinjury levels of performance are attained in only 43-65.7% of cases. Long-term complication of ACL injuries that significantly include osteoarthritis that develop later in life. One of the studies show that 50% of diagnosed patients of meniscus or ACL tear might develop osteoarthritis (OA) in the affected knee in about 10-20 years after surgery and the prevalence and severity of OA has not been shown to reduce by reconstructive surgery. Newer surgical approaches and techniques seems to reduce risk of developing osteoarthritis later in life but still questionable.

Inclusion criteria

• Patients between ages 20-40 years having unilateral ACL injury.
• Patients of both genders.
• Underwent surgical reconstruction of the ACL.
• Participants after two months of ACL unilateral reconstruction.
• Participants who attended physical therapy sessions for first two months to reduce swelling and to gain ROM post operatively.

Exclusion criteria

• Recently re-injured in 1 month. Complications such as cancer, inflammatory arthritis, disorders of autoimmune nature (Rheumatoid arthritis), anticoagulant conditions, neurodegenerative diseases (Parkinson's Disease, Motor neuron disease), organic referred pain, pregnancy, and disability compensation.
