ABSTRACT

Introduction: Patellar tendon rupture has a higher prevalence in older patients related to systemic diseases such as rheumatoid arthritis, lupus erythematosus and those with prolonged treatment with corticosteroids or antibiotic therapy. It is caused by trauma with the knee in flexion accompanied by a contraction of the quadriceps or eccentric force, the diagnosis can be omitted in up to 38% of cases. Treatment of non-recent tendon ruptures is more difficult with end-to-end techniques are complicated and difficult to perform 45 days after injury due to quadriceps retraction, fibrosis, adhesion formation, and muscle hypotrophy. Treatment options are varied, ranging from autografts to synthetic grafts using bone tunnels and fixation anchors. Case report: Our case is a 71-year-old patient with an 18-year-old patellar tendon rupture treated in two stages, starting with repairing the extensor apparatus with pes anserinus tendons, preserving their insertion and subsequently performing total knee replacement in a second surgical time and we show its evolution.
