Background: Knee stiffness is a challenging complication following complex fractures around the knee. Several treatment strategies have been described in the last decades, but clinical results and complication rates still remain as potential drawbacks. The aim of this study was to access the clinical outcomes and complications of the modified Judet quadricepsplasty following knee stiffness secondary to complex fractures around the knee.
Methods: A total of 11 patients presenting post-traumatic knee stiffness underwent modified Judet quadricepsplasty from 2014 to 2017. All procedures were performed by the same surgical team, and all patients followed the same postoperative pain control and rehabilitation protocols. No patients underwent medial approach for medial release. When necessary, medial release was performed through the lateral approach. Patients were evaluated using the Judet criteria for final range of motion after 1-year minimum follow-up.
Results: According to the Judet criteria, 4 patients (36.4%) presented excellent, 6 (54.5%) good, and 1 (9.1%) poor clinical outcomes. Blood transfusion was required in 5 patients (45.4%). No patients presented infection or wound dehiscence.
Conclusions: Although quadricepsplasty is considered a high morbidity surgical procedure, our favorable functional outcomes with very low complication rates using this modified Judet quadricepsplasty confirmed safety and efficacy of this helpful surgical procedure for the challenge of post-traumatic knee stiffness.
Level of evidence: Level 4 retrospective case series.
