Recent research is revolutionizing the treatment of patellar fractures and tendon ruptures, offering patients better outcomes and faster recovery. A biomechanical study compared two repair methods, revealing significant advantages for a particular technique.
Comparison of Patellar Fracture Repair Techniques
A controlled laboratory study investigated the biomechanical properties of transosseous tunnel repair versus suture anchor fixation for comminuted inferior pole patellar fractures treated with partial patellectomy and tendon advancement. The primary hypothesis was that suture anchor repair would result in less gapping at the repair site, with no difference in ultimate load.
Key Findings:The suture anchor group showed significantly less gapping during cyclic loading compared to the transosseous tunnel group (6.83 ± 2.23 mm vs 13.30 ± 5.74 mm; P = .047).No statistical differences were found in ultimate load between both groups.The most common mode of failure in the suture anchor group was at the anchor-suture interface, while in the transosseous tunnel group it was at the knot proximal to the patella.
Conclusions and Clinical Relevance
Suture anchors demonstrated similar strength profiles and less tendon gapping under cyclic loading compared to transosseous tunnels for the treatment of comminuted inferior pole patellar fractures. This suggests that suture anchors could offer a robust repair and allow for earlier range of motion in the treatment of these fractures.
The need for randomized clinical trials is highlighted to better understand the differences between these repair techniques and confirm their translational efficacy in clinical practice. Preliminary results indicate that suture anchors could be a promising option to improve patient outcomes.
