1INTRODUCTION: Not much has changed in the way the bone-patellar tendon-bone graft is prepared before implantation. We present a modified bone-patellar tendon-bone graft preparation technique by implying the increased cross-sectional area. MATERIAL AND METHODS: Measurements of bone-patellar tendon-bone graft were made during the reconstruction of the anterior cruciate ligament in 93 male patients. The bone part of bone-patellar tendon-bone graft 10 mm wide and the tendon part 12-14 mm wide was placed on the holder with a handle in a way which allowed sewing the edges of the patellar tendon in a shape of a tube. The circumference of the central part of the graft was measured using a suture tightened around the graft. The diameters of the circle and cross-sectional areas were then calculated using geometrical calculation. RESULTS: After preparation of the bone-patellar tendon-bone graft, the fol- lowing measures were recorded: the circumference of 30 mm, the diameter of 9.55 mm, and the cross-sectional area of 72 mm2 in 9 patients; the circumference of 31mm, the diameter of 9.87 mm, and the cross-sectional area of 76 mm2 in 15 patients, and the circumference of 32 mm, the diameter of 10.19 mm, and the cross-sectional area of 82 mm2 in 69 patients. CONCLUSION: For the average thickness (3-5 mm) and width (10 mm) of the patellar tendon graft, the cross-sectional area will be 30-50 mm2. The modified bone-patellar tendon-bone graft preparation technique made it possible to increase its cross-sectional area to 71-81 mm2.
A modified bone-patellar tendon-bone graft preparation technique increases graft cross-sectional area. This method enhances the bone-patellar tendon-bone graft for improved anterior cruciate ligament reconstruction outcomes.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Traditional bone-patellar tendon-bone graft preparation has seen limited innovation.
- A novel technique is presented to enhance graft cross-sectional area.
Purpose of the Study:
- To introduce and evaluate a modified bone-patellar tendon-bone graft preparation method.
- To determine the impact of the modified technique on graft cross-sectional area.
Main Methods:
- Measurements were taken from 93 male patients undergoing anterior cruciate ligament reconstruction.
- A technique involving sewing the patellar tendon edges into a tube shape was employed.
- Graft circumference, diameter, and cross-sectional area were calculated using geometric principles.
Main Results:
- The modified technique resulted in graft cross-sectional areas ranging from 72 mm² to 82 mm².
- Specific measurements included circumferences of 30-32 mm and diameters of 9.55-10.19 mm.
- These values represent a significant increase compared to the typical 30-50 mm².
Conclusions:
- The modified bone-patellar tendon-bone graft preparation technique effectively increases the graft's cross-sectional area.
- This enhancement has potential implications for improving anterior cruciate ligament reconstruction.
- The technique offers a viable method to optimize graft dimensions for surgical procedures.
