Background
There is considerable debate regarding the management of young patients with isolated unicompartmental osteoarthritis and previous anterior cruciate ligament (ACL) reconstruction. Medial unicompartmental knee arthroplasty (UKA) can be safely done after ACL reconstruction from a technical point of view. The procedure has been performed in younger patients with the aim of preserving bone in case of need for future revision. The short-term results are encouraging, although longer term data are necessary to evaluate the role of this procedure in these patients.
Aim
To assess the results of UKA following previous ACL reconstruction.
Patients and methods
UKA was done for eight patients with previous ACL reconstruction. Postoperative radiograph were done for all patients, follow-up period lasted for an average of 2 years, functional scoring using Oxford knee scoring system was done for all patients preoperatively, and at last, follow-up was done to assess the outcome.
Results
Last follow-up showed good results, with Oxford knee scoring system showing 50 of 60 points, no infection or loosening happened in all patients, and none of them required revision for any reason.
Conclusion
Medial UKA is a good proposed technique for patients with previous ACL reconstruction fulfilling the other criteria of unicompartmental arthroplasty.
