Abstract
To evaluate the clinical results of comminuted patella fracture fixation after an extensile surgical approach by using a tibial tuberosity osteotomy. Prospective, clinical. Six knees with displaced comminuted patella fractures had stable internal fixation after an osteotomy of the tibial tubercle. All had immediate postoperative continuous knee motion and were followed for an average of thirty-one months (minimum of eighteen months). Time to clinical and radiographic union, Hospital for Special Surgery (HSS) Knee Scores and comparisons with literature cohort studies. Clinical union of the osteotomy occurred at an average of eight weeks (range 6 to 12 weeks) and of the patella fractures at an average of eleven weeks (range 8 to 21 weeks). There was no radiographic evidence of osteotomy displacement, fracture implant loosening, migration, or failure. All patients had clinical residua, which included loss of motion, thigh muscle atrophy, and barometric complaints. HSS Knee Scores averaged 75 points with four good, one fair, and one poor result. These results were comparable to those of previously published reports of ablative surgery for this type of fracture. Comminuted patella fractures are severe injuries that usually result in some lingering morbidity. Internal fixation preserves bone stock, which facilitates future reconstructive procedures. The described tibial tuberosity osteotomy, patella eversion technique of fracture exposure improved visualization and reduction of the articular surface. The osteotomy healed in all cases and did not adversely affect the clinical results.Keywords
