Event or Problem Description
It was reported that, after a partial knee replacement surgery performed on (b)(6) 2021, the patient reported weight bearing pain at the joint line 6 months post-op.Surgeon recommended patient to wait as prior experience and literature suggests that pain would resolve as implants settled in over time.Patient was reportedly not willing to wait and opted for a revision to a tka.Surgeon noted that her long limb alignment post-surgery was ¿not that great¿.Patient was successfully converted to a cemented primary tka on (b)(6) 2021 with no augments and minimal bone loss due to the revision procedure.Also, surgeon noted that patient may not have been a good candidate for cementless uka as she had a tibia vara deformity in her left tibia "that" may have contributed to her pain.

Additional Manufacturer Narrative
H3, h6: results of investigation: engage partial knee system instructions for use specifies the following contraindications: unicompartmental replacement is contraindicated in patients who have permanent valgus or varus deformity that requires correction for the knee to function satisfactorily post-op.Prerequisites for partial knee replacement include: unicompartmental disease with a correctable deformity with minimal to no ligament releases note: tibia vara is not considered a ¿correctable deformity,¿ thus this patient is contraindicated.Investigation update: as correction action a voluntary market removal will be performed for the engage cementless partial knee system due recent complaint data that indicates that the revision rate may be trending higher than corresponding similar devices in global joint replacement registries.At this time, we have no reason to suspect that the products failed to meet any specifications at the time of manufacture.Based on this investigation, the need for corrective action may be indicated.
