Bicondylar tibial plateau fractures: principles of treatment

The management of intraarticular fractures such as tibial plateau fractures in weightbearing joints is inherently complex. Bicondylar tibial plateau fractures resulting from high energy trauma are particularly difficult to treat successfully. The objectives in managing these fractures are to obtain adequate reduction and appropriate stabilization while allowing early range of motion and limiting potential morbidity. The incidence of complications and long-term sequelae is relatively high in cases treated with traditional open reduction and internal fixation. From 1986 through 1993, 32 bicondylar tibial plateau fractures were treated at our institution. Of these, 26 were treated operatively using various methods of open reduction and internal fixation, and, more recently, indirect reduction techniques with percutaneous screw and/or external fixation. These newer techniques include arthroscopically-assisted reduction with percutaneous screw fixation or applications of a hybrid circular external fixator with or without limited internal fixation. These techniques provide adequate reduction and fixation while limiting the complications associated with traditional open methods. This retrospective study was conducted to compare these newer techniques with more traditional methods of open reduction and internal fixation (ORIF).

Closed reduction/percutaneous fixation of tibial plateau fractures: arthroscopic versus fluoroscopic control of reduction.

OBJECTIVE: To evaluate arthroscopic versus fluoroscopic reduction and percutaneous fixation of lateral tibial plateau fractures of AO/OTA Types 41.B1 to 41.B3. DESIGN: Prospective study. SETTING: University hospital. PATIENTS AND INTERVENTION: One hundred sixty-eight patients underwent operative treatment for a tibial plateau fracture from 1988 to 1995. Thirty-three of these patients had monocondylar fractures of the lateral plateau that were treated by percutaneous reduction and fixation techniques. In the first ten cases, arthroscopic control of reduction was used. The following twenty-three consecutive cases were treated by reduction and fixation solely under fluoroscopic control. The arthroscopy group was followed for a mean of fifty-two months and the fluoroscopy group for thirty-eight months. RESULTS: Nine of ten cases of the arthroscopy group had an excellent or good result in Rasmussen's knee score at follow-up. One patient with an unreduced anterolateral depression zone despite arthroscopic surgery required a total knee prosthesis after eighteen months. Sixteen cases in the fluoroscopy group met the follow-up criteria. Fifteen were graded good or excellent in Rasmussen's clinical score; sixteen were excellent or good in the radiological score. One patient claimed chronic medial joint line pain after a lateral split fracture and had arthroscopy revealing chondral degeneration on the medial side but had no pathological findings in the lateral compartment. No secondary meniscus or ligament surgery was performed in the follow-up period. CONCLUSIONS: Percutaneous treatment of fractures of the tibial plateau can be performed using arthroscopy as well as image intensification to control reduction of the joint surface. We were not able to demonstrate any significant benefit from arthroscopy compared with fluoroscopic reduction. Reduction under image intensification is technically easier in our practice, especially in serial fractures and multiply injured patients. We reserve arthroscopy for cases with significant ligament injuries and for children with fractures of the median eminence.     

Percutaneous Reduction and Internal Fixation for Monocondylar Fractures of Tibial Plateau: A Systematic Review

Instead of extensive dissection of soft tissue around the fracture site, percutaneous techniques have unique advantages in managing displaced fragments, including preservation of soft tissues, less blood loss, lower risk of complications, and earlier functional rehabilitation. However, there are few systematic reviews on the effects of percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures. A systematic search of Cochrane, EMBASE, and MEDLINE databases was performed for all publicly available data in March 2017 regarding the use of PRIF in treating monocondylar tibial plateau fractures. Basic information of included articles, surgical information, clinical outcomes, and concomitant soft tissue injuries were collected for analysis. Finally, a total of 20 articles including 561 patients were retrieved. Traffic accident was the most common cause of injury. Percutaneous techniques using bone tamp reduction were described in all studies. The majority (≥85%) of patients were classified as excellent or good according to clinical and radiological Rasmussen scores. The overall complication rate was 6.6%, with loss of reduction the most frequent complication with an incidence of 2.4%. This systematic review indicated that PRIF was an optimal alternative that physicians should consider for the treatment of monocondylar tibial plateau fractures.

Outcome of tibial plateau fractures managed with calcium phosphate cement

OBJECTIVES: To compare the use of an injectable calcium phosphate cement (Skeletal Repair System (SRS), Norian corporation, Cupertino, CA) and minimal internal fixation with buttress plating and bone grafting for lateral tibial plateau fractures. STUDY DESIGN: Retrospective analysis with 13 age, sex and fracture matched pairs of tibial plateau fractures. METHODS: Thirteen patients with lateral tibial plateau fractures treated with buttress plating and bone grafting were matched with 13 patients treated using minimal internal fixation and an injectable calcium phosphate cement (SRS). All patients were followed for a minimum of one year. The operative time, quality of reduction, maintenance of reduction and development of post-traumatic osteoarthritis was compared in both groups. RESULTS: The mean duration of surgery was 101 min in patients treated with buttress plating and bone grafting and 55 min in patients treated with SRS (P < 0.0001). Nine patients in the internal fixation and bone graft group had excellent anatomical reductions as judged on post-operative radiographs but some loss of reduction was observed in 8 of the 13 (61%) cases. All 13 patients from the SRS group had an excellent reduction on post-operative radiographs but 3 (23%) demonstrated some loss of reduction of the plateau. The mean residual plateau depression at one year was 4mm in the buttress plate group and 0.7 mm in the SRS group (P < 0.005). Two patients (15%) in the buttress plate group developed post-traumatic osteoarthritis and required knee arthroplasty. CONCLUSIONS: The use of SRS was associated with more favourable anatomical results than conventional treatment with buttress plating and bone grafting for lateral tibial plateau fractures.

Percutaneous inflation osteoplasty for indirect reduction of depressed tibial plateau fractures

Anatomic reduction of articular depression tibial plateau fractures is challenging. The authors describe a new technique using percutaneous balloon-guided inflation osteoplasty for a depressed lateral tibial plateau fracture. The fluoroscopy-guided inflation osteoplasty restores the joint surface anatomically in a minimally invasive fashion. The metaphyseal void is filled with a fast-setting fluid-phase bone substitute, and a lateral buttress plate is applied with less invasive incisions. This technique is a valid alternative for indirect reduction of depressed articular tibial plateau fractures.     

Interference Screw Technique for Arthroscopic Reduction and Internal Fixation of Compression Fractures of the Tibial Plateau

Arthroscopic reduction and internal fixation (ARIF) is recommended as state-of-the-art treatment for patients with pure compression fracture of the tibial plateau. We describe a new technique for ARIF of pure compression tibial plateau fractures that uses a cannulated, bioabsorbable interference screw. After a guide pin is placed in the center of the compressed fragment and a tamp is used to elevate the fracture (with bone grafting as desired), the interference screw is advanced over the guide pin, resulting in both elevation and buttressing of the fracture. As compared with previously described techniques in which percutaneous buttress screws were used, ARIF attained with an interference screw via the tibial metaphyseal window allows substantially improved efficiency of surgical steps, improved preservation of the soft tissue envelope, definitive articular reduction under arthroscopic visualization, use of a bioabsorbable implant, and elimination of the need for fluoroscopy.
