Bilateral staged total knee arthroplasty in obese patients.

INTRODUCTION: The purpose of this study was to compare the clinical and functional results and complications associated with staged bilateral total knee arthroplasty (TKA) performed 4-11 days apart during a single hospitalization in patients who were obese and patients who were not obese.

METHODS: We retrospectively evaluated 48 (96 knees) patients who were obese and divided into two groups based on their body mass indices (BMI). Morbidly obese patients (group A1, BMI > or = 40 kg/m2) consisted of 21 patients (42 knees), and obese patients (group A2, BMI > or = 30 kg/m2) consisted of 27 patients (54 knees). The control group (group B, BMI < 30 kg/m2) consisted of 20 non-obese patients (40 knees), who were undergoing staged bilateral procedure within the same time frame. All patients had cemented TKAs with use of posterior cruciate sparing prosthesis without patellar resurfacing. If medically stable after the first arthroplasty the patients then underwent the second arthroplasty 4-11 days later. The data on major complications and minor complications were evaluated.

RESULTS: Although, there was no statistically significant difference in overall complication rates in any of the groups, the non-obese group had fewer wound complications than the other groups (P > 0.05). No significant differences in preoperative or postoperative Knee Society score, and functional score could be demonstrated between the three groups (P > 0.05). Both obese and nonobese patients showed improvements in pain and function from pre-surgery to a minimum 2 years follow-up.

CONCLUSION: Results of bilateral staged TKAs in obese patients have low complication and high success rates and increased BMI has no negative effect on the early outcome. Bilateral staged TKA might be a good treatment alternative for the improvement of the patient's quality of life and functional and clinical outcomes.
