Successful Total Knee Arthroplasty for Hoffa and Proximal Tibial Fractures: Report of Three Complex Cases After Failed Osteosynthesis Procedures.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND Distal femoral and proximal tibial fractures often lead to nonunion and post-traumatic osteoarthritis, and total knee arthroplasty (TKA) has emerged as an effective alternative for older patients. This report includes 3 cases of successful TKA treatment. The cases involve a 42-year-old man and a 62-year-old man with Hoffa coronal fractures of the distal femur, and a 50-year-old man with a proximal tibial fracture. These patients underwent multiple osteosynthesis procedures before receiving TKA. CASE REPORT Case 1: A 42-year-old man with a displaced Hoffa's fracture had persistent knee pain. Nonunion post-initial fixation led to reoperation with iliac bone grafting and plate fixation. TKA using a Posterior Stabilized (PS)-type implant resulted in improved motion and function after 3 years. Case 2: A 62-year-old man suffered lateral condyle and ligament injuries from a displaced Hoffa's fracture. Despite plate fixation, dislocation occurred, requiring conversion. TKA with long-stem hinge-type implant, using augmentation block, led to enhanced stability and outcomes at 2 years. Case 3: A 50-year-old man's tibial nonunion, treated with plate fixation, resulted in infection and bone fusion. TKA using a constrained PS-type implant insert addressed the lateral tibial adhesions via iliotibial band (ITB) release and treated severe tibial plateau damage. Positive results were seen at 1 year. CONCLUSIONS The challenges of pseudarthrosis, like bone defects and compromised tissue, highlight the need for precise implant selection based on evaluations of bone quality, defects, knee stability, and hyperextension, rather than resorting to overly-constrained implants.
