AbstractPeri-articular knee fractures in osteoporotic or osteoarthritic bone present a challenge to fixation, mobilisation or non-operative management. We present a series of 15 proximal tibial and 11 distal femoral fractures treated with total knee arthroplasty at over mean follow-up period of 38.8 months. The mean age of the patients was 80 years. The choice of the implant and level of constraint was determined as per the nature of injury and preference of the surgeon dealing with the fracture. Patients were allowed rapid mobilisation with immediate full weight-bearing. Good clinical results were achieved with fracture healing, sound fixation and well-aligned flexible knees. Mean Knee Society knee score was 90.2; Knee Society function score was 35.5; Oxford Knee score was 39.5; and Short Form (SF)-36 physical function score was 37.3 and mental score 50.6. Good correlation was noted between Knee society knee score and SF-36 physical function score (Pearson's 0.76, p=0.001), suggesting that generic health would dictate the final function achieved, whilst high knee scores suggest the satisfactory results of the operation. Analogous to arthroplasty for hip fractures, this technique should be considered as a treatment option in elderly peri-articular knee fractures with osteoporosis and/or osteoarthritis.Copyright © 2011 Elsevier Ltd.
