Effect of Blood Flow Restriction Training in Rehabilitation of Posterolateral Corner Reconstruction of Knee: A Case Study

Résumé fourni par la source

The aim of this case report was to evaluate the outcome of blood flow resistance training in the rehabilitation of posterolateral corner reconstruction in a 26-year-old male who met with a road traffic accident eight months ago. He was diagnosed with grade 3 anterior cruciate ligament ACL and posterior horn of medial meniscus along with proximal tibia posterolateral corner injury with posterior cruciate ligament PCL tear over right knee joint following which he underwent arthroscopy surgery for the same. Though he underwent early postoperative rehabilitation as prescribed he continued to experience difficulty in climbing down the stairs swelling over right knee crepitus in the right knee joint associated with movements. He visited outpatient department of Alvarsquos College of Physiotherapy and Research Centre at Moodbidri for evaluation and further management. Residual muscle weakness and associated impairments were identified in the examination and hence was suggested to continue rehabilitation for the same. To strengthen the muscles blood flow restriction training protocol was incorporated in the routine rehabilitation of posterolateral corner reconstruction. The literature on effect of blood flow restriction training following posterolateral corner injuries is scarce and the present study outcomes could provide some insight into the same. Lower Extremity Function Scale was used to evaluate the outcomes of blood flow restriction training before and after the intervention. A total of 15 sessions of blood flow restriction training was given for quadriceps and hamstrings and the outcomes were assessed. Significant changes were observed in lower extremity functional scale from a pre-intervention score of 42.580 to post-intervention score of 6080. The increase in the scores above nine scales indicate an improvement in the functional performances of lower extremity. It can be thus be concluded that blood flow restriction training could be effective in improving residual lower extremity deficits following arthroscopic posterolateral corner injuries.
