Agency for Healthcare Research and Quality (AHRQ) presented statistics on Total Knee surgery in hospital-based care which showed Knee replacement surgery among middle-aged men and women increased 2.5-fold from 1997 to 2009.
Knee arthroplasty increased by 84% from 12/ 10,000 in 1997 to 22/ 10,000 in 2009.
Knee arthroplasty operations for women aged 45 – 64 increased 157%, from 16/ 10,000  in 1997 to 42 for every 10,000 people in the U.S.A in 2009.
For men, the rate jumped 144% with 11-28 per 10,000.  With knee arthroplasty being the 14th most common inpatient hospital procedure.
Women and men aged 65 – 84 — showed and increase of 69% for women and 55% for men during the years 1997 to 2009.
In the age group above 85 – hospitalization for knee surgery increased by 36% for men and 23% for women.
In an article in the journal Arthritis Care & Research (2008) an explanation for the increase in the pre-Medicare age population may be obesity.  Because of the obesity epidemic the incidence of arthritis at an early age in increasing.
Number of total primary knee replacements (TKR) (TKA) was 264,331 in 1997 and 431,485 in 2004 with revision surgery for knee replacements also increasing.
Frank Kelley, MD, an orthopedic surgeon at Macon, Ga. said advancements in Total knee replacement surgery techniques including  more precise surgery together with more durable implantshas influenced the fact that patients have oped for knee surgery.
In 1997, patients were told their replacement knee would be good for 10 – 15 yrs. Kelley now tells his patients to expect the artificial knee to last for twenty years. In addition physical therapy manual therapy techniques together with less invasive surgery has cut recovery time – Kelley indicated.
When the patient is ready for the  therapy stage the LegTutor will improve outcomes in physical rehabilitation.
The LegTutor™ system has been developed to allow for functional rehabilitation of the lower extremity including the knee and hip. It is used for knee rehabiliation following Total Knee replacement and knee arthroscopy. The system consists of an ergonomic wearable leg brace and dedicated rehabilitation software. The rehabilitation software allows the physiotherapist to set the game difficulty to the patients movement ability. In this way the patient undergoes controlled exercise rehabilitation practice exactly at their movement ability. In addition the LegTutor™ system gives the total knee patient constant instructions on how to perform the exercise practice and biofeedback on how well they are performing the exercise. The Quantitative biomechanical data from the evaluations in the software is used by the Physical therapist to report to the patient and the multidisciplinary team on the patients rehabilitation progress.
The Tutor rehabilitation concept is the performance of repetitive intensive exercise practice at a patient customized level. The exercises are designed in the form of challenging games that are suitable for a wide variety of neurological and orthopedic injury and disease. The games challenge the patient to perform the exercise task to their best ability and to continue exercise practice. Thus the LegTutor™ and its sister devices (HandTutor, ArmTutor and 3DTutor) allow for both upper extremity – shoulder, elbow, wrist, hand therapy and lower extremity – hip, knee, ankle physical therapy using the same rehabilitation concept.
The LegTutor™ allows for isolated and a combination of knee and three directional hip treatment. The system provides detailed exercise performance instructions and precise feedback on the patients exercise performance. Controlled exercise of multi joints within the normal movement pattern prevents the development of undesired and compensatory joint movement and ensures better performance of functional tasks.
The LegTutor™ system is used by many leading rehabilitation centers all around the world and has full FDA and CE certification. For further details see
