The purpose of the present study was to compare the functional outcomes of medial unicompartmental knee arthroplasty (UKA) between patients with lateral meniscal abnormalities (LM [+] group) on the preoperative MRI and those without lateral meniscal pathology (LM [-] group), and to evaluate the effect of a lateral meniscus lesion on functional outcomes after minimal 5 year follow-ups of medial UKA.,

With a mean follow-up time of 75 months, the outcomes of 66 knees (LM (+) were compared to the outcomes of 59 knees (LM (-) group. At the last follow-up, the clinical results were reviewed, including the KS object/function score, KOOS score, lateral side pain, and squatting capacity. At the final follow-up visit, the radiological parameters (mechanical axis and part position) were compared.

Results:
--No significant intergroup difference was found in terms of the KS object/function score, KOOS score, presence of lateral side pain and squatting ability.

--On the radiographic evaluation, there was no statistical difference in the position of the implant and mechanical axis between the two groups.

--After the surgery, the LM (+) group showed a tendency of slight varus alignment in the postoperative radiography.

Finally, regardless of preoperative lateral meniscal pathology in the MRI, the findings of UKA for medial unicompartmental knee osteoarthritis were excellent if the patients had no symptoms linked to the lateral meniscus lesion.
