Combined quadriceps lengthening (using an external ring fixator) and patellar tendon reconstruction (using a tendoachilles allograft) in a case of chronic patellar tendon rupture: A case report

Clinical Outcomes are Similar Between Graft Types Used in Chronic Patellar Tendon Reconstruction: A Systematic Review

“…Forty-eight studies were sent for data extraction after the screening process (Fig 1). Two studies were excluded because of insufficient reporting of patient demographics and outcomes, 18,33 two studies were excluded due to inadequate follow-up, 6,16 and 35 studies were excluded due to being level V evidence, 4,5,7,[9][10][11][12][13]15,[17][18][19][20]22,24,25,[27][28][29][30][31][33][34][35][36][37][38][39][40][41][42]44,[46][47][48][49][50] leaving 9 studies for inclusion in our review. 3,8,14,21,23,26,32,…”

Delta technique reconstruction of a failed patellar tendon repair: a case report

“…This is shown in the follow up imaging we did for our patient. Another described procedure to lengthen the quadriceps tendon is with the use of an external fixator (Kumar et al 2020).…”

Knee Extensor Mechanism Disruptions: A Review

“…Both noted mild limitations in knee flexion and diminished quadriceps strength, with secondary surgery for wire removal required. Kumar used a ring-fixator to mobilize the patella and QT and reconstructed the PT with an achilles allograft [62] . They noted flexion limitation of 110° and 85% of quadriceps strength compared contralaterally.…”
