Early Feasibility Study of Cartilage Defect Repair

When patients suffer from arthritis in the hip joint and fail conservative treatment, the standard surgical approach is total joint arthroplasty, where the joint is entirely removed and replaced with artificial materials. While this procedure is suitable for less active or older individuals, it is not ideal for younger, more active patients. Despite this, the number of total hip replacements in younger patients is increasing, requiring significant lifestyle adjustments to extend the implant's lifespan. Even with these efforts, most patients will face at least one total joint revision in their lifetime, each carrying an increased risk of complications and decreased patient satisfaction. As a result, total hip replacements are generally not recommended for patients aged 40 to 65 who experience activity-limiting symptoms and have exhausted conservative treatments.

The Cytex device offers an alternative treatment option for this patient population - those suffering from hip osteoarthritis (OA), unresponsive to conservative care, yet considered too young or active for total joint replacement. Notably, the Cytex implant preserves all pre-existing healthy bone stock, unlike traditional total hip resurfacing or arthroplasty procedures, allowing for future revision to conventional resurfacing or arthroplasty if needed.

The investigational device for this study, the ReNew Hip Implant, is a bioabsorbable, highly porous implant designed with mechanical properties that closely mimic those of healthy articular cartilage. The implant features a bicomponent structure, combining a biomimetic 3D woven textile with a porous 3D-printed framework.
