Reconstruction of a patellar tendon with Achilles tendon allograft for severe patellar infera — A case report

Abstract: Severe patellar infera accompanied by pathologic shortening and fibrosis of the patellar tendon is relatively an uncommmon condition but can cause recalcitrant joint stiffness and limited range of motion after knee surgery or injury. This report presents a case of a 49-year-old male with severe patellar infera and limping due to joint stiffness after three-time knee surgeries. We report a successful outcome along with a finding of the well-healed allograft after the reconstruction of a patellar tendon using Achilles tendon-bone allograft. [Copyright &y& Elsevier]
