ABSTRACT
BACKGROUND:
Single-stage total knee arthroplasty (TKA) with long-stem is a viable option to treat proximal tibial stress fracture in advance knee osteoarthritis. However, in patients with old mal-united or non-united tibial fractures, treatment becomes complicated. Therefore, our aim in this study was to monitor clinical and radiological outcome in patients presenting early or late managed by single-stage long-stem TKA.METHODS:
This retrospective study included 24 consecutive patients; all were female. Patients with recent and mobile stress fracture (Group A) were treated with close reduction and long-stem tibial component. However, in patients with old, sclerotic or mal-united fractures (Group B), open reduction, partial fibulectomy and plating with bone grafting was also performed. Outcome was monitored by tibiofemoral angle, functional Knee Society score and time taken for union.RESULTS:
The mean age of patients was 62.34 years. There were 13 patients in Group A and 11 in Group B. The mean follow up was 42.79 months (range, 18-72 months). Knee Society score improved from 29.83 ± 6.10 to 91.57 ± 4.89 in Group A and from 27.21 ± 3.32 to 89.87 ± 3.89 in Group B. Tibiofemoral angle improved from 20.57 ± 3.00° to 0.80 ± 0.46° in 21 varus knees, whereas it improved from 22.33 ± 4.61° to 0.83 ± 0.28° in three valgus knees. Iatrogenic perforation of tibial cortex occurred in one case. Union of stress fracture was achieved in all cases with a mean duration of 4.70 months.CONCLUSION:
Excellent results were obtained in both groups but were slightly lower in patients presenting late, therefore all efforts must be made to treat such cases as early as possible.Palavras-chave
