Don’t Ignore the Hamstrings after TKA

 

Total Knee Arthroplasty (TKA)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.

Knee osteoarthritis (OA) not improved by arthroscopic surgery

Knee ArthroscopyA recent study published in the Australian Journal of Physiotherapy found that arthroscopic surgery  in osteoarthritic knees offered no significant benefits, when used in conjunction with physical therapy and medications as opposed to physical therapy and medications alone.

The subjects of the study had moderate to severe OA of the knee and did not experience improvements in physical function, pain or health-related quality of life when arthroscopic surgery was added to their regimen of physical therapy and medications.
