Introduction: Floating knee injuries, ipsilateral femur, and tibial fractures are uncommon, and the exact frequency is unclear. These complicated injuries have a significant complication rate and may result in a poor prognosis. Methods A retrospective hospital-based cross-sectional study design was conducted among patients with floating knee injuries at AaBET hospital. 71 patients with floating knee injuries were treated at AaBET hospital from January 1, 2016, to December 31, 2021. Binary and multivariate logistic regression was used. The functional results of these injuries were evaluated using the Karlström and Olerud criteria. We assessed functional outcomes at 12-month post-operative follow-up. P-value < 0.05 was considered statistically significant. Results In this study, 71 patients with floating knee injuries were included. Of these, 51 (71.8%) had satisfactory results, 69 (97.2%) were the result of road traffic accident (RTA), 41 (57.7%) had open fractures, 50 (70.4%) had simultaneous injuries, and 20 (28.2%) had postoperative complications, the most common of which were wound and pin site infections (17% ).In binary logistic regression, open floating knee patients with associated injuries, patients with type 2 Fraser’s class floating knee injuries, patients who had a femur fracture treated with an external fixator, patients who underwent repeat surgery, and patients whose repeated surgery done after two weeks and patients with complication are associated with an unsatisfactory outcome. Multivariate analysis showed patients with type 2 Fraser’s classification of floating knee injuries were 8.9 times more likely than those with type 1 to experience a poor outcome (AOR 95% CI: 8.94 (1.81, 44.07), p = 0.007). Conclusion Involvement of the knee joint in floating knee injuries is the most important predictor of an unsatisfactory outcome.

“…Considering this is a retrospective study, our main limitation is related to the short follow-up. Using an external fixator at emergency treatment was also a negative factor for promoting a prolonged restriction and immobilization 16 and not verifying the presence of other associated lesions, such as knee ligament injuries.

Objective: To report the incidence of deep vein thrombosis (DVT) in ipsilateral femur and tibial fractures (floating knee). Methods: This is a retrospective, analytical, observational study conducted with the medical records of thirty patients admitted to a trauma hospital between October 2016 and July 2017 with floating knee. Results: Patients aged between 21-30 years were the most affected by the condition (36%). Seventeen patients affected the dominant limb (57%); 19 (63%) patients were classified as Fraser type I, 18 (60%) had open (compound) fractures, 16 (53%) tibial fractures, and 8 (26%) femoral fractures. External fixation of the femur and tibia (25 patients = 83%) was the most common emergency treatment. In total, 17% of patients presented deep venous thrombosis (p = 0.409). Conclusion: Despite antithrombotic prophylaxis, the incidence of DVT in the affected limb of patients with floating knee was high. We found patients with Fraser I fractures, male, and with fractures in the non-dominant limb to present a higher chance of developing DVT. Level of Evidence III, Comparative retrospective study .

“…The presence of complex fractures and accompanying soft tissue injury along with extensor mechanism problems make floating knee injuries even more complex. In the literature, studies report that the presence of open fractures, accompanying segmental fractures, and the presence of intraarticular fractures lead to poor results [10]. In this study, we examined the clinical results of the differences in floating knee injuries that can and cannot be classified according to the classification systems.…”

Background This study aims to determine the differences between the clinical and radiological results of patients based on Karlstrom-Olerud Scoring System who cannot be included in any classification for floating knee injuries and to seek an answer to the question of whether a new classification is needed. Material and Methods Seventy patients with floating knee injuries treated in our clinic were retrospectively analyzed between 2008 and 2019 in the study. The results of fractures that classifiable and unclassifiable according to the Fraser, Blake and McBryde classifications were statistically compared based on the Karlstrom-Olerud criteria. Results Seventy patients, 64 males and 6 females, participated in the study. The mean age of our patients was 32.3 ± 12.55 (18-68) years. The mean follow-up period of the patients was 30.26 ± 18.19 months (11-60 months). The results of the fractures that could not be classified according to the Blake and McBryde classification were statistically poorer than the results of those that could be classified according to the criteria (p = 0.041). The results of the fractures that could not be classified according to the Fraser classification were statistically poorer than the results of those that could be classified according to the criteria defined by Karlstrom and Olerud (p = 0.010). ConclusionWe observed that floating knee injuries that we could and could not classify led to different clinical results. In conclusion, we think that there is a need for a new floating knee classification that includes segmental fractures, patellar fractures and open fractures.
