Comparative Study of Suture Disc Suspensory Fixation Versus Interference Screw Fixation in for Tibia Fixation in Arthroscopic Reconstruction of Anterior Cruciate Ligament Using Soft Tissue

Abstract

BACK GROUND: Anterior Cruciate ligament injuries are the most common among sports related injuries. ACL reconstruction using hamstring grafts is the most common technique followed worldwide (63%) (1). Two common modalities used worldwide for Anterior Cruciate Ligament reconstruction are suspensory fixation with a Suture disc and interference fixation with an Interference screw on the tibia.

AIM AND OBJECTIVES: To evaluate the clinical outcome of a series of patients who underwent Arthroscopic ACL reconstruction with suspensory method & interference screw fixation on tibia.

MATERIALS AND METHODS: A Prospective Comparative Hospital Based Study on 30 patients (15 with suture discs and 15 with interference screws), and three clinical evaluations were taken into account at the three-month, six-month, and one-year postoperative time points, whenever a clinical evaluation for follow-up is performed. Patients of age group 20 to 45 years, those with Grade II and III ACL injuries with radiological confirmation from a knee MRI and Related meniscal damage were included in the study.

RESULTS: Studies shows IKDC scores were dependent on our regular rehabilitation protocol consisted of wearing a knee brace while walking for4 weeks in a normal patient and up to 6 weeks in a patient with generalized ligamentous laxity.

They were ambulated with crutch support during this period of 4-6 weeks. They were started on quadriceps and hamstring strengthening, active range of movement exercises during this period.

CONCLUSION: In arthroscopic ACL reconstruction employing autogenous hamstring grafts, fixation strength of the interference screw (interference) is demonstrated to have an equivalent functional outcome to suture disc (suspensory).
