Distal femur fractures have traditionally been the most challenging to treat. Restoring full motion and function to the knee may be challenging due to these fractures' proximity to the knee joint. Regardless of the treatment method, comminution, damage of soft tissue, fracture extension into the knee joint, and related injury to the quadriceps mechanism frequently concludes in suboptimal outcomes. The early surgical fixation notion, increased implant availability, early postoperative knee joint immobilization, and a better understanding of damage patterns have all significantly improved the patient's functional result. Our study focuses on distal femur fractures managed by LCP [locking compression plate] using a less invasive skeletal stabilization system [LISS]. This is a retrospective research of 18 cases of distal femur fractures in adults who had LCP treatment with the LISS. The operation at Saveetha Medical College and Hospital in Chennai runs from January 2021 to January 2022. All types of intercondylar and supracondylar fractures are included. Children's fractures and pathological fractures were not included. Age distribution, side of injury, sex distribution, anatomy of injury, mechanism of injury, damage grading, subtype of fracture, concomitant injuries, and open fractures were the parameters used to assess the cases. AP and lateral views of the X-ray were taken. A thorough preoperative workup was completed. Every case was scheduled for surgery as soon as feasible. External fixators were used in the initial treatment of complicated cases. Patients underwent locking compression plate (LCP) fixation with the LISS. Radiological examination immediately following surgery, four weeks, six weeks, eight weeks, twelve weeks, four months, and every six months for a maximum of one year.The age range of the patients was 21 to 70 years, with a mean age of 30 years. A maximum incidence of fractures was noted in individuals aged 40 to 60. Males accounted for the majority of the 18 cases, with a female-to-male ratio of 3:5. Our series was predominantly right-sided. The most frequent cause of injury has been traffic accidents. Throughout the research period, no patients were lost to follow-up. Of the eighteen cases, the majority involved distal femur fractures, with intercondylar extension accounting for a higher number of cases, and isolated supracondylar fractures following. A head injury was present in one case, and acetabular fracture in another, a Boxer’s fracturein a third case, and 2 open fractures (1 compound grade III A, the other compound grade II). The fractures took an average of 13.3 weeks to heal. It required an average of 15.3 weeks longer in cases of compound fractures. Less than six degrees of malalignment (varus, valgus) were present. Every patient exhibited optimal articular alignment.Excellent outcomes were obtained with the LISS, which combines appropriate physiotherapy with an LCP (angle stable build). In principle, an LCP implant is the best option for fractured and osteoporotic bones. In summary, the use of LCPs in the LISS appears to yield superior outcomes when managing distal femur fractures.
