ARTICLE HIGHLIGHTS
Research background
Patellar tendon rupture after total knee arthroplasty (TKA) is a catastrophic complication.
Research motivation
There has been no unified treatment for early patella tendon rupture after TKA, and long-term follow-up data are lacking. The purpose of this study was to introduce a direct repair method for early patella tendon rupture following TKA and determine the clinical outcomes and complications of this method.
Research objectives
To compare the results to similar studies to summarize potential advantages and disadvantages.
Research methods
We retrospectively reviewed the medical records of all patients who underwent TKA from 2008 to 2021 and were eligible for inclusion in this study. Patients with early patellar tendon rupture after TKA were included.
Research results
For all the 12 patients who underwent direct repair for early patellar tendon rupture, three patients failed: One (8.3%) for infection and two (17.6%) for re-fracture. The two patients with re-fracture both underwent reoperation to reconstruct the extensor mechanism and the patient with infection underwent revision surgery.
Research conclusions
This direct repair method for early patellar tendon rupture is not an ideal therapy.
Research perspectives
We suggested that direct repair should not be the preferred method to treat early patella tendon rupture, but other reconstruction methods should be boldly chosen.
