Journal Article
The effect of body mass index on the outcomes of cementless medial mobile-bearing unicompartmental knee replacements
2023
Overview
Purpose
Given an increasingly overweight population, unicompartmental knee replacements (UKRs) are being performed in patients with higher body mass indices (BMIs). There are concerns that cemented fixation will not last. Cementless fixation may offer a solution, but the long term results in different BMI groups has not been assessed. We studied the effect of BMI on the outcomes of cementless UKRs.
Methods
A prospective cohort of 1000 medial cementless mobile-bearing UKR with a mean follow up of 6.6 years (SD 2.7) were analysed. UKRs were categorised into four BMI groups: (1) ≥ 18.5 to < 25 kg/m
2
(normal), (2) 25 to < 30 kg/m
2
(overweight), (3) 30 to < 35 kg/m
2
(obese class 1) and (4) ≥ 35 kg/m
2
(obese class 2). Implant survival was assessed using endpoints reoperation and revision. Functional outcomes were assessed.
Results
Ten-year cumulative revision rate for the normal (
n
= 186), overweight (
n
= 434), obese class 1 (
n
= 213) and obese class 2 (
n
= 127) groups were 1.8% (CI 0.4–7.4), 2.6% (CI 1.3–5.1), 3.8% (CI 1.5–9.2) and 1.7% (CI 0.4–6.8) with no significant differences between groups (
p
= 0.79). The 10-year cumulative reoperation rates were 2.7% (CI 0.8–8.2), 3.8% (CI 2.2–6.6), 5.2% (CI 2.5–10.7) and 1.7% (CI 0.4–6.8) with no significant differences between groups (
p
= 0.44). The 10-year median Oxford Knee Score were 43.0, 46.0, 44.0 and 38.0 respectively.
Conclusion
Cementless mobile-bearing UKR has low 10-year reoperation and revision rates across in all BMI groups, and there are no significant differences between the groups. Although higher BMI groups had slightly worse functional outcomes, the improvement in function compared to preoperatively tended to be better. This study suggests that BMI should not be considered a contraindication for the cementless mobile-bearing UKR.
