Conditions

Health Condition 1: S835- Sprain of cruciate ligament of knee

Interventions

Intervention1: Anterior cruciate ligament reconstruction: 1. ACL reconstruction using BPTB autograft: a) Patient position- The patient will be placed supine on an operative table. b) Portal placement

A femoral tunnel, with a diameter equal to that of the BPTB graft, is arthroscopically drilled, up to 30 mm in length, over the guidewire. e) Tibial tunnel preparation: Tibial guide pin is passed out

Eligibility

Inclusion criteria

Inclusion criteria: a) Isolated Anterior cruciate ligament (ACL) tear b) Patient symptomatic by instability i.e. having at least one episode giving way of the involved knee c) Mature patient with 16-45 year of age d) Undergoing ACL reconstruction using Bone Patellar Tendon Bone autograft or Hamstring tendon autograft. e) Consenting to participate in the study

Exclusion criteria

Exclusion criteria: a) Patients who refuse to participate in the study b) Associated meniscal injury requiring more than one-third resection or repair c) Any degree of extension lag d) Associated more than grade 2 PCL, LCL or MCL injury e) Associated osteoarthritis of the injured knee f) Associated pathology of contralateral hip, knee or ankle that would affect gait g) Any associated pathology of ipsilateral hip or ankle that would affect gait h) Any pre-injury pathology of the concerned knee

Design outcomes

Primary

Measure	Time frame
Gait analysis parameters : a) Walking velocity (m/s) b) Peak knee flexion angle, degrees c) Peak knee flexion moment, Nm/kg.m d) Peak knee adduction angle, degrees e) Peak knee adduction moment, Nm/kg.m f) EMG activity of the quadriceps and the hamstrings g) Hip extension moment, Nm/kg.m Timepoint: The Gait analysis parameters will be assessed prior to surgical reconstruction of ACL, and at 3 and 9 months post-operatively	—
