ConforMIS Inc., a medical technology company that develops, manufactures, and sells joint replacement implants that are customized to fit each patient's unique anatomy, has announced the results from two clinical studies presented at the ICJR Pan Pacific Orthopaedic Congress, August 10–13, 2016.
In an independent, prospective, single-center investigator-initiated study of 62 total knee replacement patients in “fast track” surgeries, those who received an iTotal CR had significantly better outcomes compared to patients who received a traditional “off-the-shelf” implant. Specifically, iTotal CR patients had a significantly shorter length of stay than off-the-shelf patients (1.6 days vs. 2.7 days, p=0.004). Additionally, a higher proportion of iTotal CR patients were discharged within 24 hours (66 percent vs. 30 percent, p=0.006) with a significantly higher proportion of iTotal patients discharged directly to home (97 percent vs. 80 percent, p=0.0496) as opposed to a skilled nursing facility. Further, a significantly higher proportion of iTotal patients were able to achieve range of motion greater than or equal to 120˚ (84 percent vs. 45 percent, p=0.003).
“I have been using ConforMIS’ iTotal CR for over 5 years and this data reinforces the superior outcomes and quicker recovery that I have observed in my patients,” said Richard Buch, M.D., a fellowship-trained orthopedic surgeon with Dallas Limb Restoration Center in Plano, Texas and clinical investigator for this study. “Knee replacement patients today are demanding more from their surgery. They want to get home faster and return to their daily activities. In my experience, the ConforMIS iTotal CR allows them to do that more frequently than any other implant I’ve used in my 30 years as an orthopedic surgeon.”
Based on the results of the study and other published economic data, Dr. Buch concluded that ConforMIS iTotal CR has the potential to save hospitals approximately $2,200 per patient. The recent rollout of the Comprehensive Care for Joint Replacement (CJR) model has incentivized hospitals to better manage costs and care coordination for knee replacement patients. Under the CJR model, which has been implemented in 67 Metropolitan Statistical Areas, the Centers for Medicare & Medicaid Services (CMS) has a stated goal of saving $150 million over 5 years. Two of the most costly components across the entire episode of care for total knee replacements are the initial inpatient hospital stay and the use of rehabilitation facilities after discharge. Based on a previously published cost analysis of length of stay1, by shortening the average length of hospital stay by 1.1 days compared with off-the-shelf implants, Dr. Buch concluded that there is potential for in-hospital cost savings of approximately $1,100 per patient. Similarly, based on another previously published cost analysis of discharge destination2, Dr. Buch concluded that a lower proportion of iTotal patients being discharged to skilled nursing facilities has the potential for an additional savings of approximately $1,100 per patient for a total potential savings of approximately $2,200 per patient.
Separately, in an update to an ongoing multi-center prospective study of 740 consecutively enrolled total knee replacement patients, those who received an iTotal CR implant were significantly faster than patients with an off-the-shelf implant at completing three functional tests of daily living: walking, getting in and out of a chair and walking up and down stairs. Study investigators used a validated functional test known as the Aggregated Locomotor Function (ALF) test, in which blinded operators assessed patients’ ability to perform these activities of daily living. Additionally, an analysis using the 2011 New Knee Society Score (KSS) found no statistically significant differences. ConforMIS provided financial support for this study.
“Our current healthcare environment is demanding that its treatments not only improve the lives of patients, but do so at a cost that does not overburden the payer system,” said Philipp Lang, MD, MBA, Chief Executive Officer and President of ConforMIS. “Multiple studies have demonstrated that ConforMIS customized knee replacements offer superior patient outcomes compared to traditional off-the-shelf implants, and now we have additional evidence showing that our iTotal CR system can help reduce some of the biggest cost contributors for total knee replacement by shortening the average length of hospital stay and reducing the proportion of patients discharged to skilled nursing facilities. We believe our iTotal CR system offers cost savings to the hospital across the entire episode of care.”
