Clinical Trial of an MRI Based Patient Specific Focal Knee Resurfacing

Status Recruiting

Clinical Trial Summary

The goal of this study is to evaluate the efficacy, safety and performance of the Episealer® device in a sample size of 30 patients and on the long term (10 years follow-up).

Clinical Trial Description

Lesions in the cartilage are common disorders. In the knee, cartilage lesions are found in over 50 % of all arthroscopies, where 25 % of these are of focal character and the majority are found in the medial femoral condyle. The quality of life of patients with focal cartilage defects is significantly affected and it has been shown that the quality of life is affected to the same extend as in patients scheduled for knee replacement. Arthroscopy lavage and debridement micro fracturing, mosaic plasticity as well as osteochondral autograft transplantation (OATS) are methods used for treatment of the lesions. Some have shown to help the patients but there is an ongoing treatment gap especially for patients with knee lesions and early osteoarthritis. Episurf Medical has developed a Focal Knee Resurfacing (FKR) implant, the Episealer® implant. The implant is used for treatment of focal cartilage lesions of the lateral or medial femoral condyle in order to alleviate pain and improve range of motion. The implant and surgical instruments are customized to each patient's joint anatomy, position, and size of injury, based on patient-specific images (MRI). The Episealer® device is CE marked. The Episealer® implant consists of a peg and a hat. The implant exists in five different diameters (12,14,17, 20 and 25mm), depending on the lesion size. The shape of the hat is circular or oval. The Episealer® implant is made of biocompatible cobalt/chromium/molybdenum alloy. To enhance the osseointegration, the implant is coated with biocompatible hydroxyapatite onto an interlaying biocompatible pure titanium coating. A previous study (S57685) showed that Episealer is a viable option for focal cartilage lesions of the distal femur not responding, or not eligible for, biological treatment options (eg. microfracturing). This device is a good solution when there are no alternative treatments, except prosthesis surgery, available. The goal is to evaluate the efficacy, safety and performance of the Episealer® device in a larger sample size and on the long term. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
