ABSTRACT

INTRODUCTION: This study explored a minimally invasive technique for harvesting the superficial band of the quadriceps tendon. By using a conventional graft tendon stripper, the procedure aims to obtain the full length of tendon fibers necessary for anterior cruciate ligament (ACL) reconstruction. The study aimed to determine if this technique can produce grafts of sufficient length and diameter.

METHODS: From September to October 2023, we conducted a study using full-body Thiel-embalmed cadavers over 18 years of age without pathology-related alterations in lower limb anatomy. The mid-diameter of the graft was measured at its midpoint, and the peripheral diameter was taken at the ends. The length of the triple-folded graft was measured from end to end. A digital vernier caliper measured the length and mid-diameter, and a graft sizer measured the peripheral diameter.

RESULTS: Sixteen quadriceps tendon autografts were harvested from 16 knees of 8 cadavers (mean age: 64.7 ± 9.9 years). The minimally invasive harvesting technique yielded a mean graft length of 289.0 ± 10.3 mm before folding, a mean mid-diameter of 9.7 ± 0.7 mm, a mean peripheral diameter of 8.5 ± 0.4 mm, and a mean length of 93.1 ± 4.7 mm after triple folding. Gender-based comparisons showed no significant differences. Correlations between graft dimensions and height were not statistically significant.

DISCUSSION: The findings of this study indicate that the minimally invasive harvesting of the superficial band of the quadriceps tendon resulted in adequate graft dimension. Gender-based comparisons revealed no statistically significant differences in these dimensions between males and females. Additionally, correlation analysis showed weak to moderate correlations between graft dimensions and height, none of which were statistically significant, indicating no meaningful relationship between height and graft dimensions.

ABSTRACT

BACKGROUND: Perioperative blood loss remains a challenge in total hip arthroplasty (THA). Although tranexamic acid (TXA) is widely used for hemostasis, the efficacy of oxidized regenerated cellulose (ORC) powder as an adjunct in blood management for THA via the direct anterior approach (DAA) remains underexplored. This study aimed to evaluate the effects of ORC powder on perioperative blood loss, hematological parameters, and clinical outcomes in direct anterior THA.

METHODS: A total of 133 patients who underwent primary THA via the DAA were enrolled in the study. The patients were divided into two groups: the ORC powder group (combination of ORC powder and topical TXA, n = 53) and the control group (topical TXA alone, n = 80). The demographic and clinical information, operative time, intraoperative bleeding volume, estimated total blood loss (eTBL), hidden blood loss (HBL), trends in hemoglobin, hematocrit, postoperative pain scores using a numeric rating scale (NRS), and adverse events were analyzed. Clinical outcomes were assessed using the Japanese Orthopedic Association score.

RESULTS: The ORC powder group had significantly lower eTBL (679.1 ± 230.1 mL vs. 875.8 ± 292.9 mL, p < 0.0001) and HBL (424.1 ± 194.5 mL vs. 558.6 ± 264.2 mL, p = 0.002). Postoperative pain scores at postoperative day 7 were lower in the ORC powder group (1.9 ± 1.6 vs. 2.9 ± 2.2, p = 0.009). The clinical outcomes were excellent, and no significant differences were observed in complication rates between the groups.

CONCLUSION: ORC powder effectively reduced perioperative blood loss in THA via the DAA without increasing complication rates. ORC powder has the potential to be a valuable adjunct in optimizing blood management strategies in THA.
