“…A similar trend of maintenance of BMI levels above the ideal was observed in men and women. Other studies have observed a greater tendency of women to lose weight post-surgery and a lower propensity for men to either lose or gain weight in both the pre- and postoperative periods, in addition to a lower propensity for weight gain in older patients 24, 25. Stets et al 26 also found that only 21.5% of their patients presented a reduction in BMI; in the other patients, weight was maintained (59.2%) or increased (19.9%).…”

ObjectiveSeveral studies show that patients undergoing total knee arthroplasty (TKA) tend to maintain or gain weight after the procedure, which would result in increased wear of the prosthesis and new surgical interventions in a smaller period of time in comparison with patients with adequate body mass index (BMI). The aim of this study was to investigate the effect of TKA surgery on these patients’ BMI.MethodsInitially the records were analyzed, chosen at random from 91 patients undergoing TKA during the period from August 2011 to July 2013. Patients were stratified by BMI as normal weight (BMI between 20 and 25), overweight (BMI between 25 and 30), and obesity (BMI > 30). They were re-evaluated in a minimum period of 18 months.ResultsThe mean age of the sample population was 68.1 years; 69.1 for men and 67.2 for women. The mean preoperative BMI was 27.24 kg/m2. Among the study participants, in the preoperative period, 17 patients had normal weight, 65 were overweight, and nine were obese. Postoperative analysis showed weight loss in 41 patients (46%), and weight gain in 50 patients (54%). The mean postoperative BMI was 27.16 kg/m2, in general, experiencing a slight decline in the mean BMI of 0.08 kg/m2.ConclusionPatients who underwent TKA did not achieve significant reduction in BMI after surgery.

“…The majority of TKA patients are overweight or obese [19], and as physical activity levels and weight do not appear to change in a high proportion of patients [7,50], rehabilitation clinicians may need to more strongly encourage behavior change. Behavioral programs targeting diet, activity and weight loss may need to be developed to prevent or delay the development of further comorbidities.…”

Purpose We sought to identify patient-reported barriers and facilitators to healthy eating and physical activity among patients before or after knee arthroplasty. Materials and methods Twenty patients with knee osteoarthritis aged 40–79 years who had knee arthroplasty surgery scheduled or completed within 3 months were interviewed. Interview topics included perceived barriers and facilitators to healthy eating and activity before or after surgery. Interviews were coded and analyzed using constant comparative analysis. Results Interviews were completed with 11 pre-operative (67.1 ± 7.6 years, 45.5% female, BMI 31.2 ± 6.3) and nine post-operative patients (61.7 ± 11.7 years, 44.4% female, BMI 30.2 ± 4.7 kg/m2). The most commonly identified personal barriers to healthy eating identified were desire for high-fat/high-calorie foods, managing overconsumption and mood. Factors related to planning, portion control and motivation to improve health were identified as healthy eating facilitators. Identified personal barriers for activity included pain, physical limitations and lack of motivation, whereas facilitators included having motivation to improve knee symptoms/outcomes, personal commitment to activity and monitoring activity levels. Conclusion Identifying specific eating and activity barriers and facilitators, such as mood and motivation to improve outcomes, provides critical insight from the patient perspective, which will aid in developing weight management programs during rehabilitation for knee arthroplasty patients.

“…Several studies have examined changes in weight following knee replacement, but results have been inconsistent. For example, some evidence suggested that patients experience no change in weight while others observed weight gains after the knee replacement [20–24]. A recent systematic review also suggested that there was not conclusive evidence on weight changes following joint replacement [25]; however previous studies have not been limited to overweight and obese patients.…”

Patients Less Likely to Lose Weight Following a Knee Replacement

BACKGROUND Knee replacement typically results in reduced pain and improved function, but it is unclear if these improvements lead to weight loss. OBJECTIVE The purpose of this study was to examine weight change patterns pre- and post-operatively among overweight/obese knee replacement patients. METHODS The study evaluated 210 overweight/obese patients from the Osteoarthritis Initiative who underwent a knee replacement during an 8 year longitudinal study. Average annual weight changes during 1–2 year intervals prior to, including, and subsequent to knee replacement were categorized as loss (≥−2.5%), maintain (>−2.5% to <2.5%), and gain (≥2.5%). Weight changes across time intervals were compared using logistic regression with generalized estimating equations, adjusting for demographic, health, and knee factors. RESULTS On average, patients lost (−0.6 kg/yr) during the interval when the surgery was performed, but weight gain (0.9 kg/yr) in the initial post-operative interval represented an overall net weight gain (0.3 kg/yr) compared to pre- surgery. Continued weight gain (0.3 kg/yr) was also seen among patients with additional follow-ups. Patients were significantly less likely to have a meaningful weight loss in the time interval immediately following the surgery compared to the interval in which the surgery took place (odds ratio=0.37, 95% confidence interval: 0.18, 0.79). CONCLUSION Overweight and obese patients initially lost weight during the interval including knee replacement, however they were less likely to lose >2.5% of their weight in the 1–2 years immediately after the surgery. Knee replacement patients may benefit from weight management interventions both pre- and post-operatively.
