Extensor apparatus reconstruction with Leeds-Keio ligament in total knee arthroplasty

Repair of ruptured quadriceps tendon with Leeds–Keio ligament following revision knee surgery

“…Its utility in the reconstruction of patellar tendon ruptures following knee replacement surgery was subsequently reported by Aracil and Salom [3].…”

Complications involving the extensor mechanism after total knee arthroplasty

“…With the exception of two prospective investigations [2,3], all the studies analysed are retrospective, leading therefore to a low level of evidence. One of the most remarkable flaws in many of the investigations is they did not report separately on the different aetiologies of the extensor mechanism disruption, neither on the non-operative or operative treatments and their relative outcomes.…”

Acellular dermal graft augmentation in quadriceps tendon rupture repair

“…The results achieved in these other studies were considered a success, given the patient population. 12,14 A case report of quadriceps rupture after TKA treated with primary repair reinforced with Dacron tape cerclage offered pain free ambulation with good range of motion at 1 year. 26 While these materials seem to offer promise, the data regarding their use are somewhat limited, and the results have not been consistent.…”

“…15--19 Unfortunately, in chronic situations, including those involving a TKA, the results have been less satisfactory. 1,4,9,14,20,21 Chronic or delayed repair of these tendons is complicated by musculature retraction, fatty infiltration of the tendon, scar tissue formation, muscle atrophy and poor tendon quality from previous surgeries. 22--24 Although problems with the extensor mechanism of the knee are not uncommon, there are few reports detailing the effects of treatment with TKA.…”
