Background:
Total knee replacement is a standard treatment for severe osteoarthritis of the knees. It is however, still a novel procedure in Nigeria. Literature on the procedure and outcome of management are sparse in Nigeria.
Objective:
This study aimed at describing Total Knee prosthetic Replacement as it is practiced in National Orthopaedic Hospital, Lagos.
Methods:
Data on patients treated with Total knee replacement between 2006 and 2010 were analyzed retrospectively. The standard anterior approach, with a medial parapatellar incision under pneumatic tourniquet was used in all cases.
Results:
There were a total of 59 knees in 48 patients operated, with a female: male ratio of 5:1. Patients were in the sixth to ninth decades of life. There was a statistically significant relationship between duration of symptoms and severity of angular deformity. The average pre-operative Knee score (KS) was 27 and average function score (FS) was 43. Average duration of surgery was 126.38 minutes. Tourniquet removal after wound closure was associated with reduced intra-operative blood loss (p < 0.05). Post-operative complications included peri-prosthetic fracture (1.69%), post-operative anaemia (8.47%), superficial wound dehiscence (3.39%) and foot drop (3.39%). The mean post-operative KS and FS increased to 80 and 75 respectively.
Conclusion:
Total knee replacement, though a novel procedure in our institution is beneficial to patients with severe osteoarthritis. A long term outcome study is being planned.
