SHORT-TERM RESULTS OF PERCUTANEOUS, ARTHROSCOPICALLY ASSISTED OSTEOSYNTHESIS OF TIBIAL PLATEAU FRACTURE

Abstract

In tibial plateau fracture, anatomical reduction of articular surface with stable fixation can restore the mechanical axis and allow early mobilization. Concomitant management of ligamentous and meniscal injury is essential for preservation of knee function. Open reduction and internal fixation has a significant complication rate.Percutaneous,fluoroscopically and arthroscopically assisted osteosynthesis with special fracture reduction and fixation technique can achieve the purpose of management of tibial plateau fracture, while limiting the soft tissue damage.

18 cases, including all J. Schatzker’s type of tibial plateau fracture, were operated with minimal access surgical technique. Male patients were predominant. The age ranged from 22 to 61 (mean 33.5). Detail pre-operatives planning with CT scan were performed in 16 patients. Fluoroscopy, arthroscopy and special fracture reduction and fixation technique were applied to all cases. All 18 cases could be reviewed. Follow up period ranged from 1 to 4 years (mean 2.3 yr.). Outcome was assessed by HSS Knee Score, standing radiograph and arthroscopy (2 cases).

According to HSS score, 14 patients were rated as excellent (100 to 85), 3 good (84 to 70), 1 fair (69 to 60) and none poor (< 60). Subjectively, 14 patients were satisfied with the treatment. 13 patients were working and participating in sport before injury. 15 took no analgesic, 2 took it once a week and 1 more often. In standing radiograph, only 2 patients showed minimal narrowing of joint space. There was no significant complication directly associated with the procedure.

Percutaneous, fluoroscopically and arthroscopically assisted osteosynthesis is a safe and effective minimal access surgical procedure. Precise pre-operative planning and special fracture reduction and fixation technique are all crucial for success. Short-term clinical outcome is encouraging.
