Abstract
Background: One of the body's main joints for bearing weight is the knee. Its issues are likewise difficult to resolve. Damage to this joint can cause abnormalities in the alignment, stability, and motion of the knee, which impairs function. Objective: To compare the functional and radiological outcome in AO type C1 distal femur fractures fixed with locking plate versus dynamic condylar screw. Methods: The study comprised 94 patients aged 18 to 60 years who had an isolated distal femur fracture and an Arbeitsgemeinschaft für Osteosynthesefragen (AO) type C1 closed fracture. Patients with diabetes mellitus, chronic renal disease, chronic liver disease, ischemic heart disease, pathological fractures, head injuries with a Glasgow coma scale of less than 14, and malignancy were excluded from the sample. The patients were assigned by lottery to groups A and B. In groups A and B, they were treated with dynamic condylar screws (DCS) and locking plate fixation, respectively.. Results: Among 94 patients, 30 (63.8%) were men and 17 (36.2%) were women in Group A; similarly, 33 (70.2%) were men and 14 (29.8%) were women in Group B. Patients in group A had an average age of 38.8±6.19 years, whereas those in group B had an average age of 39.5±7.36 years. 02 patients (4.2%) in Group-A and 05 patients (10.6%) in Group-B experienced infection. The union rate was 45 (95.7%) in group A (locking plate fixation technique) and 40 (85.10%) in group B (dynamic condylar screw technique). 35 (74.46%) in group A, 08 (17.1%) in good, 03 (6.38%) in average, and 01 (2.1%) in poor; in group B, 25 (53.2%) in excellent, 09 (19.2%) in decent, and 10 (21.3%) had average and 03(6.3%) had poor functional outcome. Conclusion: In terms of clinical and radiological evaluation, the type C1 distal shaft femur fixation with locking plate performs better than the dynamic condylar screw, which has a lower infection rate and better union and functional success
