Purpose of this research is to study the effect of 8-weeks physical rehabilitation exercises on motor function and micro-structure of injured meniscus in athletes.
Design
Clinical experiment was composed of 24 athletes with meniscus injury that were selected by purposive sampling and were divided into control and experimental groups randomly.
Settings and conduct
Method and type of this study is semi-experimental and applied. This study was accomplished in orthopedic clinics to find subjects, rehabilitation faculty lab to record variables, exercise site to implement protocol, hospital for meniscectomy, and pathobiology lab to prepare the tissue. Surveys were done before and after 8 weeks (control: not exercised and experimental: exercised; intergroup comparison) and after surgery (intragroup comparison).
Participants/Inclusion and exclusion criteria
Study entry criteria include subjects being volunteer for meniscectomy; not more than six months is passed from their injury; is volunteer to participate in the exercise program.
Condition for not entering this study was subsiding from it in the middle of the research for any reason.
Intervention groups
Torque, balance, range of motion, and proprioception of the injured knee were measured before and after 8 weeks (control: not exercised; experimental: selective rehabilitation exercise).
Meniscectomy was performed on both groups and during meniscectomy injured meniscus tissue was removed.
Then surface topography, surface profile, surface roughness, number of surface fibrocartilages, and diameter of fibrocartilages were deliberated in both groups.
Main outcome variables
Eight weeks of selective rehabilitation program improved motor function (knee muscle torque; balance; ROM; and knee proprioception) and micro-structure (meniscus surface roughness; number of meniscus fibrocartilages; diameter of fibrocartilages) in injured athletes.
