The iBalance UKA System is indicated for use in unicompartmental knee arthroplasty as a result of:
- Moderately disabling joint disease of the knee resulting from painful osteoarthritis or post traumatic arthritis;
- Correction of functional deformities;
- Revision of previous unsuccessful unicompartmental knee replacement or other procedure;
- As an alternative to tibial osteotomy in patients with unicompartmental osteoarthritis.
These components are single use only and are intended for implantation with bone cement.
The iBalance PFJ System is indicated for use in patellofemoral joint, (PFJ) knee arthroplasty as a result of:
- Degenerative arthritis in the distal femur and patella;
- A history of patellar dislocation or fracture;
- Failed previous surgery (arthroscopy, tibial tubercle elevation, lateral release) where pain, deformity or dysfunction persists.
These components are single use only and are intended for implantation with bone cement.
When used concurrently, the Arthrex iBalance UKA and PFJ systems create the Arthrex iBalance BiCompartmental Arthroplasty System. The Arthrex iBalance BiCompartmental Arthroplasty System is intended to be used as a multicompartmental knee arthroplasty in patients with:
- Moderately disabling joint disease of the knee resulting from painful osteoarthritis or post traumatic arthritis;
- Correction of functional deformities;
- Revision of previous unsuccessful partial knee replacement or other procedure.
The iBalance BiCompartmental Arthroplasty System is not intended to be used as a dual-condyle or tri-compartmental knee.
These components are single use only and are intended for implantation with bone cement.
The Arthrex iBalance Partial Knee System encompass the following FDA cleared devices:
- Arthrex iBalance UKA System
- Arthrex iBalance PFJ System
- Arthrex iBalance BiCompartmental Arthroplasty System
These systems are comprised of femoral, tibia and patellar components for use in knee prosthesis.
The provided FDA 510(k) clearance letter for the Arthrex iBalance Partial Knee System does not contain the information requested regarding acceptance criteria and the study proving the device meets those criteria, particularly in the context of an AI/algorithm-based medical device.
This document is a clearance letter for a physical medical device (a knee replacement system), not an AI-powered diagnostic or treatment algorithm. The "performance data" mentioned refers to non-clinical and in-vivo electromagnetic simulation related to the device's "MR Conditional" status, which is about its safety in an MRI environment, not its diagnostic or therapeutic accuracy as an AI would have.
Therefore, I cannot extract the requested information (such as sample sizes for test/training sets, expert consensus, MRMC studies, etc.) from this document because it is not relevant to an AI/algorithm-based device study.
To provide the information you're looking for, I would need a 510(k) clearance letter or a clinical study report specifically detailing the performance evaluation of an AI/algorithm-based medical device.
§ 888.3520 Knee joint femorotibial metal/polymer non-constrained cemented prosthesis.
(a)
Identification. A knee joint femorotibial metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral condylar resurfacing component or components made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components made of ultra-high molecular weight polyethylene and are intended for use with bone cement (§ 888.3027).(b)
