<p>Quadriceps tendon rupture is the rarest injury with an incidence of 1.37/1,00,000/year. A patellar fracture is the most common injury associated with extensor mechanism lag, but it is rarely found to have quadriceps rupture rather than patellar tendon rupture. Normally when patella fracture occurs the force is disseminated at the bone level rather than at the muscular level. In this case, the force has disseminated at both muscle and bone leading to fracture of patella and quadriceps tendon rupture. Here we report a case of patellar fracture along with quadriceps tendon rupture.<strong></strong></p>

Background: Extensor mechanism failure secondary to knee replacement could be due to tibial tubercle avulsion, Patellar tendon rupture, patellar fracture or quadriceps tendon rupture. An incidence of Patella tendon rupture of 0.17% and Quadriceps tendon rupture of around 0.1% has been reported after Total knee arthroplasty. These are considered a devastating complication that substantially affects the clinical results and are challenging situations to treat with surgery being the mainstay of the treatment.Case Description: We report here an interesting case of a patellar tendon rupture of one knee and Quadriceps tendon rupture of the contralateral knee following simultaneous bilateral knee replacement in a case of inflammatory arthritis patient. End to end repair for Quadriceps tear and augmentation with Autologous Hamstring tendon graft was done for Patella tendon rupture.OUTCOME: Patient was followed up for a period of 1 year and there was no Extension lag with a flexion of 100 degrees in both the knees.DISCUSSION: The key learning points and important aspects of diagnosing these injuries early and the management techniques are described in this unique case of bilateral extensor mechanism disruption following knee replacements.

Mechanism Function

Extensor mechanism failure in total knee arthroplasty (TKA) can present as quadriceps tendon rupture, patella fracture or patella tendon rupture. Component malrotation, excessive joint line elevation and previous lateral release are some of the risk factors contributing to extensor mechanism failure in TKA. Partial quadriceps tendon rupture and undisplaced patella fracture with intact extensor mechanism function can be treated conservatively. Extensor mechanism failure in TKA with disruption of the extensor mechanism function should be treated operatively as it is associated with poor function and extensor lag. It is recommended that acute repair of patella or quadriceps tendon rupture are augmented due to the high risk of re-rupture. Chronic ruptures of the extensor mechanism must be reconstructed as repair has a high failure rate. Reconstruction can be performed using autograft, allograft or synthetic graft.

Very few case reports have been reported on traumatic separation of the bipartite patella along with quadriceps tendon rupture. These reports relate to separation of superolateral bipartite patella (Saupe type 3). We describe a new variant which to our knowledge has not been described or classified so far, which is purely a superior bipartite patella with traumatic separation and complete functional disruption of the extensor mechanism of the knee in a young patient working in the army which was managed with open reduction and internal fixation along with repair of the extensor mechanism of the knee achieving complete functional recovery.

Tendon Pathology

Extensor mechanism injuries are not uncommon in young active individuals. Patellar tendon is a part of extensor mechanism of the knee which is commonly ruptured due to forced eccentric contraction against flexed knee. There have been reports of pathological changes in the patellar tendon which eventually lead to the rupture. The common pathologies include hypoxic tendinopathy, mucoid degeneration, calcific tendinopathy and tendolipomatosis. We report a rare case of ossified proximal patellar tendon rupture in a fit and active skittle player, who sustained indirect injury to knee while playing soccer. The rupture was confirmed on examination and radiographs. We discovered intraoperatively that the ruptured proximal patellar tendon was ossified which was sequentially repaired with two Krackow sutures, JuggerKnot suture anchor and finally augmented with Leeds Keio tape. Postoperatively, a knee brace was used to immobilise in knee extension with progressive increase in range of motion. This report supports the pool of evidence suggestive of patellar tendon pathology in causing ruptures.
