Abstract
Introduction Floating knee injury (FKI) occurs as a result of a high-velocity impact. We assessed the radiological and functional outcomes of FKIs treated by various fixation methods, by damage control orthopedics (DCO) or early total care (ETC). Materials and methods We investigated 46 patients with FKI who were operated on between January 2013 and January 2018 at the RL Jalappa Hospital and Research Center, Kolar, India. Functional assessments were evaluated using Karlström and Olerud’s criteria (KOC). Based on their treatments, the patients were divided into the damage control orthopedics group (n = 21) and the ETC group (n = 25). Statistical analyses were used to obtain and compare summary data. Results The data of 46 patients were collected. Fractures were classified using the modified Fraser’s classification. Five patients were not included in the final analysis because of death due to complications in the immediate postoperative period. In patients managed by DCO, after radiological union, the functional outcome was excellent in three cases, good in eight, fair in seven, and poor in two. The average time required for radiological union of the femur was 10.75 ± 1.482 months (P = 0.001); for tibia union, it was 10.25 ± 1.682 months (P = 0.011). The average range of knee flexion was 85°± 16.059° (P = 0.001), which was statistically significant. In patients managed by ETC, there were six cases with an excellent functional outcome, 13 with a good outcome, and two with a fair outcome. The average time required for radiological union of the femur was 9.29 ± 1.765 months (P = 0.006); for the tibia, it was 9.05 ± 1.161 months (P = 0.012). The average range of knee flexion was 100° ± 10.954° (P = 0.001), which was statistically significant. Fat embolism was noted in eight cases; four of these patients died due to multiorgan dysfunction. This was the major life-threatening complication in the early definitive fixation group. In the DCO group, only three cases had fat embolism, with one death due to multiorgan dysfunction. Early postoperative infection was a concern in the ETC group, evident in six cases. Conclusion The classification system for FKI needs further research, which must include multiple parameters. Fracture classification and patient selection are crucial considerations in deciding the best treatment for a particular fracture.

Abstract
The "floating knee" is defined as fractures of the ipsilateral femur and tibia, which consists of a spectrum of injury, and may be in isolation or part of multiple system trauma for a given patient. A floating knee may compromise limb viability due to severe soft-tissue and vascular injury. Expeditious fracture reduction and patient resuscitation are crucial, while type and timing of provisional and definitive management is guided by the extent of injury to the involved extremity and associated systemic injuries. Numerous surgical techniques are available to treat the floating knee, including external fixation and internal fixation with plates or intramedullary nails. Fracture complexity and severity of soft-tissue injury present challenges, with articular injuries potentially more debilitating in the long term. Complications such as infection, deep vein thrombosis, knee stiffness, nonunion, malunion, and posttraumatic arthrosis after these injuries should be considered.

Abstract
INTRODUCTION Floating knee is a flail knee joint resulting from fractures of the shafts or adjacent metaphyses of the femur and the ipsilateral tibia. It is usually associated with several complications and mortality. This study was designed to present our experience with the treatment of this injury. MATERIAL AND METHOD This study was performed between January 2004 and December 2014. 224 cases of floating knee injuries gathered from the 34,480 lower extremities trauma files were studied, and the target information recorded. The injuries most frequently occurred in subjects between 16 and 35 years of age (60.71%), and in male subjects (85.71%). The most frequent mechanism of injury was traffic accident (92.85%). External fixation was the common type of treatment (82.14%) in emergency or as a definitive treatment. The treatment was performed within 24 h of the trauma. We performed a 36-month follow up with clinical examination, radiographs, assessing the complications, and using the Modified Cincinnati Rating System Questionnaire (MCRSQ) and the Karlström/Olerud Score (KOS) to evaluate the progression of the outcomes. RESULTS Early complications included 8 cases of compartment syndrome, 60 open fractures and 24 partially amputated limbs. A total amputation was performed in 3 patients. The most common late complication was heterotopic calcifications of the knee (n = 68, 30.6%). Good scores for MCRSQ and KOS were obtained only after patients were sent to a reference center for knee surgery. CONCLUSIONS Our experience revealed that the complication rate associated with floatingknee injuries remains high, regardless of the performed treatment. Surgeons should focus on reducing complications while treating these severe injuries.

[PMID: 29885963 DOI: 10.1016/j.injury.2018.05.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 05/19/2018] [Accepted: 05/22/2018] [Indexed: 02/05/2023]
Abstract
BACKGROUND The surgical outcome of floating knee injuries is difficult to predict. The high-velocity nature of the injury, complex fracture pattern and associated soft tissue/visceral injuries may have some impact on the functional outcome. The present study evaluates the variables affecting the clinical and radiological outcomes of floating knee injuries. MATERIALS AND METHODS The clinical, radiological and functional outcome (Karlstrom and Olegrud criteria) of 89 patients with 90 floating knee injuries were evaluated at the end of one year who were managed in our level 1 trauma center between January 2013 and December 2016. The details of the injury, fracture pattern, management and complications were collected retrospectively from their records. RESULTS There were 81 (91.1%) males and 8 (8.9%) females with mean age of 34.34 ± 12.28 years. The mean time for tibia and femur union was 9.52 (±6.6) and 10.5 (±7.37) months. There was significant delay (p < 0.005) in time taken for union in segmental femur fractures (14.3 ± 9.6 months) compared to nonsegmental femur fractures (8.68 ± 5.18 months). Such significant difference in time taken for union was not seen in tibial segmental (10.6 ± 4.62 months) and nonsegmental fractures (9.05 ± 7.27 months). As per the Karlstrom and Olegrud criteria, there were 22 (24.4%) excellent, 26 (28.9%) good, 24 (26.7%) fair and 11 (12.2%) poor outcome. There were 15 patients with malunited tibia, 6 with malunited femur, 10 with limb length discrepancy and 39 with knee stiffness. 28 (33.3%) patients underwent major additional procedures such as bone grafting, re-fixation or bone transport or tendon transfer. It was observed that open tibia fracture, segmental fracture, intra-articular fracture, additional surgical procedures, initial external-fixator (ex-fix) application were significantly associated with development of knee stiffness, limb shortening, malalignment and unsatisfactory (Karlstrom and Olegrud fair to poor) functional outcome. CONCLUSION Open tibial fractures, segmental fractures, intraarticular involvement, additional surgical procedures and initial external fixator application are the poor prognostic indicators of floating knee injuries.
