“…A mismatch between the tibial and femoral component, and/or size of the bearing itself, might lead to failure [21]. Saragaglia et al [30] consider that the navigation of only the tibial bone cut is a reasonable option and invaluable in the positioning of mobile bearing UKA, where the risk of overcorrection should not be underestimated.…”

Purpose Surgical treatment options for medial compartment osteoarthritis of the knee include high tibial osteotomy, total knee arthroplasty or unicompartmental knee arthroplasty (UKA), depending on the patient's age, level of physical activity and the degree of deformity. Methods In this study, we evaluated the long-term results of patients who underwent the Oxford cemented meniscalbearing unicondylar knee prosthesis through a minimally invasive approach including a clinical, functional and radiographic assessment. Results Favourable clinical and radiological outcomes were registered overall at ten years after surgery. Overall results of UKA according to the American Knee Society (AKS) using Insall's criteria showed an excellent or good outcome for 492 knees (96.28 %), fair for 11 (2.15 %) and poor for eight (1.57 %) in the post-operative long term. Conclusions We believe that with appropriate surgical technique, patient selection, prosthetic design and specific training, surgeons should achieve good outcomes with the added advantages of a minimally invasive approach. High volume for this technique is important in our opinion.

“…In these studies, patient-specific guides were applied to accurately reproduce preoperative planning during surgery. Guides or navigation systems were also used in other types of interventions around the knee to support the surgeon in performing tibial plateau fracture reduction 34 , high tibia osteotomies [35][36][37][38][39][40][41][42] or TKA 43,44 .…”

The accurate reduction of tibial plateau malunions can be challenging without guidance. In this work, we report on a novel technique that combines 3-dimensional computer-assisted planning with patient-specific surgical guides for improving reliability and accuracy of complex intraarticular corrective osteotomies. Preoperative planning based on 3-dimensional bone models was performed to simulate fragment mobilization and reduction in 3 cases. Surgical implementation of the preoperative plan using patient-specific cutting and reduction guides was evaluated; benefits and limitations of the approach were identified and discussed. The preliminary results are encouraging and show that complex, intraarticular corrective osteotomies can be accurately performed with this technique. For selective patients with complex malunions around the tibia plateau, this method might be an attractive option, with the potential to facilitate achieving the most accurate correction possible.

“…Third, at the time of implant positioning, excessive lateral placement in extension should be avoided as this may lead to an overload of the lateral part of the tibial plateau when the knee is flexed to 30° [29,30]. Finally, internal rotation of the tibial component when performing lateral UKA must accommodate the typical "screw-home" mechanism that occurs during knee flexion, and this should be included when performing the sagittal tibial cut [31].…”

Unicompartmental femoro-tibial osteoarthritis usually affects the medial compartment of the knee, but in 10%, the lateral compartment is primarily involved. Femoral osteotomy is attractive to avoid TKA in younger patients with low-grade unicompartmental osteoarthritis and a valgus deformity. However, only limited functional results can be expected for patients with Ahlback grade 2 or greater osteoarthritis. Moreover, because of previous skin incisions and hardware removal, TKA after femoral osteotomy remains a complex procedure with poor functional results. Unicompartmental knee arthroplasty for both the medial and the lateral compartments has been performed since the 1970s. In a patient with involvement of only one compartment, a medial or a lateral UKA can provide a quicker recovery and enhanced function when compared to TKA. In addition, it preserves bone stock and can be "easily" revised by a TKA. Technical improvements, combined with strict patient selection, have resulted in ten year survivorships greater than 90%. However, lateral UKA is technically more challenging than medial UKA due to the lower number of indications, as well as the functional anatomy of the lateral compartment. The goals of this article are to present up-to-date information concerning indications, patients' selection, surgical technique and results of lateral compartment UKA.
