AJSM Webinar Series - September 2021: Patellar Tendon Repair-Operative Treatment of Acute Patellar Tendon Ruptures

Operative Treatment of Acute Patellar Tendon Ruptures

Pdf Summary

This study investigates the outcomes and complications of anchor and transosseous suture repairs for acute patellar tendon ruptures. The researchers reviewed data from 361 patients who underwent primary repair within 45 days of injury between 2006 and 2016. Of these patients, 91.7% were male, with a mean age of 39.8 years. There were 321 transosseous repairs and 53 anchor repairs. The results show that the rerupture rate was significantly lower in anchor repairs compared to transosseous repairs (0% vs 7.5%, respectively). There was no significant difference in age, sex, tourniquet time, body mass index, infection rate, or time to release from medical care between the two groups. However, there were more reoperations in the transosseous repair group compared to the anchor repair group (11% vs 3.8%, respectively), although this difference did not reach statistical significance. The study also reported a lower infection rate in the transosseous repair group (1.6% vs 7.5%, respectively), but again, this difference was not statistically significant. The findings suggest that anchor repair may have advantages over transosseous repair in terms of lower rerupture rates, but further research, including randomized controlled trials, is needed to confirm these results.
