Abstract: Objectives: To do detailed comparative study on bone patellar tendon bone graft and the hamstring tendon graft for reconstruction of anterior cruciate ligament and evaluation of results.
Materials and Methods: This was prospective compised of thirty patients presented with knee instability and/or pain at SMIMER Surat from year August 2012 to August 2015. They were diagnosed clinically and confirmed by MRI to have anterior cruciate ligament tear. Patients with 18 to 40 years of age with ACL tear that occurred more than 4 weeks without previous surgery/ligament damage were included in study while patients with <18 or >60 years of age and evidence of osteoarthritis on plain radiographs were excluded. Outcome evaluation was done using Tegners’ score & Lysholm knee score and patients were followed at 4,8,12 weeks, 6 months, 1 year
Results: Over all mean post-operative Tegners’ score were 5.86 with median value 6 with scores range 3 to 8. Mean postoperative score for bone patellar tendon bone graft patients was 5.66 and with median value of 6 and ranges 3 to 8. Mean postoperative score for Hamstring graft patients was 6.06 and with median value of 6 and ranges 3 to 8. Mean post-operative Lysholm score was 78.6 with median value of 87.5 and scores ranging 23 to 100. Mean postoperative score in Hamstring graft group was 81.13 with median value 92 and range 23 to 100. Mean postoperative score in bone patellar tendon bone graft group was 76.13 with median value 85 and range 27 to 99. Complications like superficial or deep infections, ligament laxity, instability, arthrosis or revision were not seen in our study.
Conclusions: Arthroscopic/open anterior cruciate ligament reconstruction by either quadrupled hamstring tendon graft or bone patellar tendon graft gives satisfactory results in short term follow up in terms of patient satisfaction, activities of daily living and return to near normal or higher activity than before surgery. Large scale study with long term follow up is required to corroborate findings of the study and to find out long term functional results in the two graft groups.
