A new project involving ACU’s Exercise Science team will investigate the impact arthroscopic meniscus surgery for degenerative tears has on knee function and osteoarthritis development has been awarded two Danish grants totally AU$360,000.
The aim of the study is to evaluate differences in pain, function, quality of life and pre-cursors for knee osteoarthritis (OA) in individuals following arthroscopic meniscus surgery for degenerative versus traumatic meniscus tears. Meniscal tears increase the risk of knee OA, however the efficacy of surgical intervention to lower the risk of OA is equivocal. This may be related to previous work not distinguishing between traumatic and degenerative type tears; degenerative tears are typically observed in sedentary individuals aged 35-55, whereas traumatic tears are typically observed in active sports people, aged <35 years.
The study will examine changes in symptoms, knee joint loading during walking, and bone structure prior to, and 12 months post meniscal surgery in 150 individuals with either degenerative or traumatic meniscus tears.
Dr Mark Creaby, Lecturer & Assistant Head of School, Exercise Science, ACU Brisbane campus will play a key role in the project. He will be measuring knee joint load during walking as well as interpreting the resulting data.
The project funding includes a face-to-face research forum for all study investigators in 2013. Mark will visit the research team in September to work with them on the project. The research team includes several high profile international researchers, including Prof. Stefan Lohmander, one of the world’s leading OA researchers and editor-in-chief of the highest-ranking orthopedic journal (Osteoarthritis & Cartilage).
The project is co-funded by two grants:
