PMID 37131357WHAT IT FOUND
Patients with obesity, diabetes, hypertension or dyslipidemia had poorer knee scores and worse walking after high tibial osteotomy.
These metabolic factors, not just alignment or strength, predict a tougher recovery. Screen for them before surgery.
Key findings
01JOA scores at 12 months postoperatively were poorer in patients with MS-related factors.
02Significant differences in knee extensor muscle strength, range of motion, pain, and gait speed were observed between groups with and without metabolic syndrome factors.
03Patients with obesity showed decreased knee extension range of motion, prolonged 10 m gait time, decreased knee extension muscle strength, and increased pain during gait.

What it does not show
The study did not track whether the metabolic conditions improved or worsened during the recovery period, so it is unclear if better management of these factors would change the outcome. The sample size was too small to analyze results separately for men and women. Many patients were excluded due to missing data or other surgeries, which may limit how broadly the results apply. This was an observational study, so it shows an association but cannot prove that metabolic factors directly cause poorer outcomes.
Declared interests
The authors declared no conflicts of interest and no funding.
The easy way to misread this
Do not assume that surgical correction of alignment alone will resolve symptoms in patients with metabolic syndrome. The study found that alignment did not correlate with the final functional score, while metabolic factors did. This suggests that the biological impact of conditions like obesity and diabetes plays a significant role in recovery, independent of the mechanical correction.
