In Children with cerebral palsy, knee flexion contracture ha
The impact of knee flexion contracture (KFC), functional mobility, and their association in children with Cerebral Palsy was studied which inferred that the severity of KFC has an effect on function.

Analysis was done on 2,838 children and were defined into 3 groups: no (less than 4°), mild (5–14°), and severe (more than 15°) KFC on physical examination. The Functional Mobility Scale (FMS) levels were categorized: using wheelchair (level 1), using assistive devices (level 2–4), walking independently (level 5–6). Standing and transfer ability and Gross Motor Function Classification (GMFCS) were assessed.

Results: —
--Of the 2,838 children, 73% had no, 14% mild, and 13% severe KFC.

--KFC increased from 7% at GMFCS level I to 71% at level V. FMS assessment (n = 2,838) revealed around 2/3 were walking independently and 1/3 used a wheelchair.

--With mild KFC, the odds ratio for FMS level 1 versus FMS level 5–6 at distances of 5, 50, and 500 meters, was 9, 9, and 8 respectively.

--Correspondingly, with severe KFC, the odds ratio was 170, 260, and 217. In no, mild, and severe KFC 14%, 47%, and 77% could stand with support and 11%, 25%, and 33% could transfer with support.

To summarize, knee flexion contracture is normal in children with cerebral palsy, and the severity of KFC has an effect on function. Increased GMFCS levels, diminished functional agility, and decreased standing and transfer capacity all increased the proportion of children with KFC. As a result, early detection and treatment of progressive KFC are critical.
