Native patellar tendon injuries are seen in younger patients compared to quadriceps tendon
ruptures. Up to a third of the patients may have local (antecedent tendinopathy and cortisone …

Extensor tendon rupture is a rare but serious complication after total knee arthroplasty (TKA)
that impairs active knee extension, thereby severely affecting knee function. Surgery is …

Purpose The purpose of this study was to compare mid-term results of three different
reconstructive techniques for chronic patellar tendon disruption after total knee arthroplasty …

Extensor mechanism failure in total knee arthroplasty (TKA) can present as quadriceps
tendon rupture, patella fracture or patella tendon rupture. Component malrotation, excessive …

Background Postoperative rehabilitation after extensor mechanism reconstruction (EMR)
with allograft following total knee arthroplasty (TKA) is not standardized. This meta-analysis …

Background Extensor mechanism rupture is a severe complication with an incidence of 0.1–

complication and results in significant morbidity and severe functional limitations …

Patellar tendon ruptures are rare, but debilitating injuries are typically seen in young active
males in the third and fourth decades of life. They can occur as a single acute injury or from …

Ruptures of the quadriceps tendon (QTRs) are uncommon. If the rupture is not diagnosed,
chronic ruptures may develop. Re-ruptures of the quadriceps tendon are rare. Surgery is …
