To determine whether quadriceps femoris muscle atrophy following knee surgery can be accurately estimated using regional muscle thickness measurements.
Assessed 18 patients (9 men, 9 women; mean age 44.4 years) following meniscectomy using magnetic resonance imaging of both operated and non-operated thighs.
Calculated total quadriceps femoris volume across 11 axial slices and measured muscle thickness across anterior, lateral, and medial regions at proximal, mid-, and distal thigh sites.
Applied stepwise linear regression analysis to evaluate the relationship between inter-limb differences in muscle volume and muscle thickness.
Quadriceps femoris volume showed no statistically significant difference between operated limbs (806.6 ± 220.0 cm³) and non-operated limbs (913.7 ± 241.5 cm³).
Inter-limb muscle volume differences correlated significantly with muscle thickness differences across three specific sites: anterior proximal thigh, lateral mid-thigh, and anterior mid-thigh (R = 0.93, P < 0.01).

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Observational imaging study demonstrates that quadriceps thickness predicts muscle volume loss after meniscectomy, indicating an efficient method for tracking post-surgical atrophy.
