Comparison of quadriceps and hamstring muscle size and strength between young athletes following knee surgery and healthy controls.

ABSTRACT:

Objectives

This study compared the size and strength of the quadriceps and hamstring muscles in young athletes who had undergone previous knee surgery (POST) to sex- and age- matched, healthy controls (SAM).

Methods

A total of 18 (nine POST and nine SAM) participants volunteered to participate in the study's procedures. Of the nine POST participants, six had underwent anterior cruciate ligament reconstruction, two underwent medial patellofemoral ligament reconstruction and one had undergone patellar tendon repair. Maximal voluntary isometric contractions assessed absolute strength (MVIC_ABS) of the quadriceps and hamstrings. Muscle size was quantified as muscle cross-sectional area (mCSA) from panoramic ultrasound images. Relative strength (MVIC_REL) was
