Clinical Orthopaedics and Related Research recently published an article entitled “Quadriceps and Hamstrings Muscle Dysfunction after Total Knee Arthroplasty.” The article discusses a study of dysfunction in the quadriceps and hamstring muscles following Total Knee Arthroplasty (TKA).
Using bilateral isometric strength tests and EMG measures of quads / hams co-activation the study found that the difference in loss of strength between the muscle groups was not significant; both were weakened equally.
The authors claim that in post TKA rehab the hamstrings are often neglected relative to the emphasis placed on quadricep strengthening and retraining. Their conclusion from this study is that the hamstrings should be included with the quadriceps as the primary focus in post total knee arthroplasty rehabilitation.

Many physical therapists use orthopaedic/orthopedic rehab protocols frequently throughout their daily practice. Former Calgary Flames and Canadian Olympic Team Physical Therapist, Terry Kane, runs a website called OrthopaedicProtocols.com . The site links to dozens of orthopaedic/orthopedic protocol documents from all over the internet. The documents included come from sites such as:
- Advanced Orthopaedics and Sports Medicine
- Bringham and Womens Hospital
- Cappagh National Orthopaedic Hospital
- Cochrane Review
- Massachusetts General Hospital
- Cincinnati Sportsmedicine and Orthopaedic Center
- Dr. Millet / Steadman Hawkins
- Gundersen Lutheran
- University of Kentucky
- University of Minnesota Orthopaedics
- University Sports Medicine – University of Buffalo
- Massachusetts General Hospital
- Kevin Freedman MD, Orthopaedic Specialists
…and many more. Protocol documents available are varied, from ankle sprains to post-op artificial discs and almost everything in between. Outcome and radiological documents are also available.
From the site:
- Ownership / Editor: The site is 100% privately owned and edited by Licensed Canadian Physical Therapist, Terry Kane (www.terrykane.ca)
- Authors: This database consists of hypertext links to protocols authored by licensed healthcare professionals or academic institutions. All protocols are currently part of the public domain on the internet or have been submitted by the authors themselves.
- Mission: The site was designed to help students and clinicians find diagnostic, treatment and rehabilitative protocols to help them in managing their patients. The protocols are not presented to replace the care and advice of a licensed healthcare professional but rather for educational purposes of healthcare professionals only. This website does not endorse any of the protocols presented, but rather, provides them as a library for visitors to access and evaluate for themselves independently.
- Target Audience: The site was designed and authored for an audience of licensed healthcare professionals and students.
Terry has put together a very useful resource with this vast collection of protocols available online. Much can be learned from studying the differences and similarities between the many available. The site also offers the ability for practitioners to submit their own protocols to be added to the system.
One feature that I would like to see added to the site is the ability for site visitors to rate the various protocols available. Doing so would require that users register with the site, something that is not currently required or possible. I believe the lack of registration required is for ease of use and to prevent people from being concerned about privacy issues. However, I feel that allowing those interested in registering to give their ratings would make the site even better.

Boing Boing has an interesting article on the (fairly) new AlterG treadmill. From the article: “The AlterG is no ordinary treadmill, though. It is a super fancy, super-expensive treadmill that isolates the lower body in a vacuum and literally takes off percentages of your body weight using technology developed by NASA.”
The treadmill can significantly reduce stress through the joints during ambulation or running and allows the user to set what percentage of their body weight they have to support. It sounds like a great way to enable early rehabilitation or to allow physical activity for disabled and overweight people who might otherwise not be able to get effective cardiovascular exercise. It can also be used to allow injured athletes to train through injuries.
The treadmill looks futuristic and comes with a price tag that is also somewhat out of this world coming in at around $24, 500 USD. While this sounds expensive, it’s probably not that outrageous if you were to compare it to the cost of purchasing exercise equipment such as swimming treadmills which aim to acheiving similar goals.
The AlterG is supposedly showing up increasingly often in physical therapy clinics.
