What this trial studies

This is a prospective, observational, mid-term, multicenter follow-up enrolling about 150 patients across four centers in Germany. The Univation XF Pro implant is used in routine clinical practice according to the authorized Instructions for Use, and patients are treated as part of standard care. Clinical data from those procedures and follow-up visits will be recorded in an electronic case report form (eCRF). The main goal is to collect real-world clinical data on the safety and performance of the redesigned Univation XF Pro unicompartmental implant.

Who should consider this trial

Good fit: Adults aged 18–75 with isolated medial degenerative knee disease who are indicated for a primary medial unicompartmental knee replacement and meet the implant IFU (intact cruciate and lateral ligaments, passively correctable leg axis, varus deformity under 15°, sufficient range of motion, and able to give informed consent) are ideal candidates.

Not a fit: Patients who are pregnant, younger than 18 or older than 75, have BMI ≥ 40, are high surgical risk (ASA > III), have significant lateral compartment disease or gross instability, or otherwise fall outside the implant IFU are unlikely to benefit from this enrollment.

Why it matters

Potential benefit: If results are favorable, the data could support that the redesigned implant provides reliable pain relief and improved knee function with a low rate of complications for patients with isolated medial knee osteoarthritis.

How similar studies have performed: Partial (unicompartmental) knee replacements have demonstrated good outcomes in many prior studies, but published mid-term data specific to the redesigned Univation XF Pro implant are limited.
