Abstract

"My Hip Resurfacing (HR) has been recalled. What will happen to me?" This is the question of every patient who underwent an implant recall, a highly stressful event for both patients and physicians. Triggered by a 11.64% failure rate at 7 years, a recall process started for Adept HR with head diameter less than 48 mm. We report our experience in the recall process of 40 patients with the above-mentioned components. One patient underwent revision surgery due to an adverse reaction to metal debris at 5-year follow-up. None of the patients were scheduled for revision, with an estimated survival rate of 97.6% at 7 years. Implants were well positioned with an average acetabular inclination angle of 37°. Cobalt and chromium blood levels were below the safety threshold of clinical relevance. Functional scores were excellent. In the case of a well-positioned device with normal ion levels, a good performance of the implant is generally observed. Even if we experienced a very low revision rate, this may certainly get worse over time since not all possible failures are predictable, thus requiring a careful periodic follow-up.
