We describe our 10-year experience with total knee arthroplasty in patients who are included in the Malawi National Joint Registry.


A total of 127 patients underwent 153 total knee arthroplasties (TKAs) between 2005 and 2015. The mean duration of follow-up was 4 years and 3 months (range, 6 months to 10 years and 6 months). The study group included 98 women and 29 men with a mean age of 65.3 years (range, 24 to 84 years). Nine patients were human immunodeficiency virus (HIV)-positive.


The primary indication for surgery was osteoarthritis (150 knees), and the mean preoperative and postoperative Oxford Knee Scores were 16.81 (range, 4 to 36) and 45.61 (range, 29 to 48), respectively. Four knees (2.6%) were revised because of early periprosthetic joint infection (1 knee), aseptic loosening (1 knee), and late periprosthetic joint infection (2 knees). There were no perioperative deaths. In the group of 9 patients who were HIV-positive, there were no early or late complications and the mean Oxford Knee Score was 47 (range, 42 to 48) at the time of the latest follow-up.


This study demonstrated good short-term results following 153 primary TKAs performed in a low-income country. Level of Evidence Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
