Purpose: To assess the behaviour of fresh frozen cancellous allograft used for supporting the reconstructed articular surface in impacted tibial plateau fractures.
Materials and Methods : Between May 2004 and May 2008, 13 cases of impacted tibial plateau fracture were evaluated retrospectively. All fractures were treated with open reduction-internal fixation after restoration of the tibial plateau surface and insertion of fresh frozen cancellous allograft chips for subchondral support. Mean age was 46.6 (31∼65) years. Average follow-up period was 36 (13∼58) months. The radiological and clinical result for every patient was assessed according to the modified Rasmussen’s system and Lysholm’s knee score.
Results: According to last follow-up weight bearing A-P X-ray, the fresh frozen cancellous allograft incorporated soundly in all cases and no complications such as joint depression, fracture reduction loss, angular deformity, and malunion were found. The mean time to complete bone union was postoperative 10±0.7 weeks. The mean range of motion was 135 (115∼145) degrees. The mean Rasmussen’s radiological score at last follow up was 15.3 (10 cases: excellent, 3 cases: good). The mean Lysholm’s knee score at last follow up was 88.2±4.3.
Conclusion: We concluded that fresh frozen cancellous allograft in impacted tibial plateau fractures showed good results in terms of bone union and functional improvement and was considered to be a good structural supporter.
