I am sorry, but based on the text provided, I cannot answer your request. The document is a 510(k) approval letter from the FDA for a total hip system, not a study report or technical specification document that would contain the detailed information you are asking for regarding acceptance criteria and device performance studies. The letter only states that the device is "substantially equivalent" to legally marketed predicate devices, but it does not provide details about the specific studies conducted or their results.
§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
