Banff Sport Medicine Research Group

Mission Statement/Vision:

To establish an innovative environment that supports and facilitates leading-edge bone and joint research in a community setting. Banff Sport Medicine Research Group, in collaboration with research partners and organizations, will enhance clinical care, patient education and the overall quality of life for people with bone and joint disease by designing, researching and implementing evidence-based medicine.

Research Team Members

We are a team of clinicians actively conducting clinical research

Dr. Laurie Hiemstra

Dr. Laurie Hiemstra

Laurie has published over 30 peer-reviewed research manuscripts, as well as numerous invited articles and book chapters. In addition to her medical and surgical training, Laurie completed a PhD. in neuromuscular physiology in 2003.

Laurie’s current research is primarily focussed on Patella Instability including diagnostic accuracy, surgical techniques, rehabilitation, and functional outcomes. In 2014 she was awarded the ISAKOS Patellofemoral Traveling Fellowship and she is a member of the International Patellofemoral Study Group. Laurie is highly involved in teaching nationally and internationally as an expert in her field.  She is also a Clinical Associate Professor at the University of Calgary. Laurie’s additional research interests include ACL reconstruction surgical techniques, biomechanics and functional outcomes; and, neuromuscular control following knee injury.
Dr. Mark Heard

Dr. Mark Heard

Mark is a Clinical Associate Professor at the University of Calgary, and he is the Fellowship director at BSM. Mark teaches nationally and internationally, and he is an expert instructor for the AANA comprehensive knee course. Mark’s main area of research interest is outcomes following knee ligament reconstruction.

His current research projects include ACL reconstruction surgical techniques, assessing indicators of return to sport readiness, and the influence of secondary pathology on patient function after surgery. Mark has also written two book chapters focussed on PCL Reconstruction and PLC Instability. Mark’s other research interests include live articular cartilage transplantation, outcomes in isolated osteochondral defects, and, the effect of bony defects on surgical selection and outcomes in shoulder instability.
Dr. Greg Buchko

Dr. Greg Buchko

Greg’s primary research interest is outcomes following ACL, PCL and multi-ligament knee reconstruction. Greg’s areas of research interest include the factors that influence surgical outcomes as well as assessment for return to sport following ACL and PCL reconstruction; predictors of success after meniscal repair; and surgical treatment and functional outcomes for shoulder instability.

Presentations and Teaching

In an effort to improve outcomes for all patients, the BSM team is actively involved in presenting the results of their clinical research nationally and internationally. In the past year, BSM research has been presented at international conferences in North America, South America, Europe and Australia.

Some recent presentations include:

  • “Patient-reported Quality-of-Life is Lower in Patients with Graft Laxity following Hamstring Autograft ACL Reconstruction.” COA Annual Meeting, June 2018, Victoria Canada.
  • “Age at time of Surgery but not Sex is related to Outcomes after Isolated MPFL Reconstruction.” COA Annual Meeting, June 2018, Victoria Canada
  • “Surgical Approach to Posterolateral Corner Reconstruction.” COA Annual Meeting, June 2018, Victoria Canada
  • “Which Risk Factors Predict Outcome following Isolated MPFL Reconstruction? A Multivariate Regression Analysis.” APKASS & AOA Congress, June 2018, Sydney Australia.
  • “Surgical Stabilisation of the Patella: Failure Rates and Patient Risk Factors.” APKASS & AOA Congress, June 2018, Sydney Australia.
  • “Clinical Outcomes in Patella Alta and the Effect of MPFL-R on Patellar Height.” 18th ESSKA Congress, May 2018 Glasgow UK.
  • “Relationship Between Anatomical Risk Factors, Articular Cartilage Lesions, and Patient Outcomes Following Medial Patellofemoral Ligament Reconstruction.” 18th ESSKA Congress, May 2018 Glasgow UK.

The BSM surgeons and physicians are actively involved in education and teaching. All team members are committed to training the next generation of health care specialists. In collaboration with the University of Calgary, the BSM surgeons provide specialty training for a surgical Fellow each year. The surgeons regularly teach surgical techniques to colleagues and trainee orthopaedic surgeons in cadaver labs via their roles with professional organisations such as AANA. The BSM team also provides evidence-based updates on the prevention and treatment of musculoskeletal injuries, with a focus on knee and shoulder instability, within their local and national networks.
