Use of a raft construct through a locking plate without bone grafting for split-depression tibial plateau fractures.

Purpose: To review the outcome after open reduction and internal fixation using a periarticular raft construct through a locking plate without bone grafting for split-depression tibial plateau fractures.

Methods: Records of 38 knees in 31 men and 7 women aged 25 to 75 (mean, 42.7) years who underwent open reduction and internal fixation using a periarticular raft construct through a locking plate without use of a bone graft or bone substitute for split-depression (>5 mm) proximal tibial plateau fractures (Schatzker type II or AO/OTA type 4.1 B3) were reviewed. The integrity of the articular surface was assessed using radiographs. The Rasmussen radiological score and clinical score, the Lysholm knee score, and the Tegner activity score were also assessed.

Results: The mean follow-up period was 22.8 (range, 6-36) months. All patients achieved bone union after a mean of 13.2 (range, 8-26) weeks. The mean range of motion was 118º (range, 100º-130º). The Rasmussen radiological score was excellent in 27 patients, good in 9, and fair in 2. The Rasmussen clinical score was excellent in 15 patients, good in 21, and fair in 2. The Lysholm knee score was excellent in 26 patients, good in 8, and fair in 4. 32 of the 38 patients recovered to their preoperative Tegner activity scores. Only one patient with severe comminution had loss of reduction after full weightbearing.

Conclusion: Fixation using a periarticular raft construct through a locking plate without use of a bone graft or bone substitute for split-depression proximal tibial plateau fractures is a viable option.
