With more of the functional anatomy unaffected, UKA offered a more rapid recovery and better restored the knee kinetics than total knee arthroplasty in selected patients.[1],[2] The exceptional long-term survivorship and excellent function of UKA has been reported by a number of studies.[2],[3],[4] However, the progression of lateral compartmental osteoarthritis (LCOA) is one of the major downsides of UKA.[4],[5] Other downsides to UKA are the wear of the polyethylene (PE) bearing, aseptic loosening, tibial femoral instability, fatigue failure of the tibia tray and infection.[5],[6]
LCOA progression due to an altered stress pattern in the cartilage has been described in the literature.[7] Wear of lateral compartment has been attributed to abnormal cartilage stress, which can be strongly related with the postoperative lower limb alignment.[8],[9] In addition, the tibial component inclination may affect the contact stress and load percentage in the lateral compartment.[10],[11] Numerous finite element (FE) analyses of UKA have already advised on the postoperative lower limb alignment and inclination of the tibial component, but their results vary.[10],[12],[13] The aim of this study was to analyze the influence of the postoperative lower limb alignment and the tibial component coronal inclination on static knee biomechanics after mobile-bearing UKA using FE analysis.
The enhanced macro handover procedure starts by MN obtaining new LCoA and RCoA, then [MAP.sub.N] receives LBU message to bind the MN's LCoA with RCoA.
Procedure Enhanced_Macro_Handover MN Obtains LCoA (Local CoA).
When a Mobile Node moves between routers that fall under the same MAP, only the LCoA changes and an update is sent to the MAP as shown in Fig.
This means that HMIPv6 handles global mobility via the RCoA and local mobility via LCoA. HMIPv6 reduces signaling load outside the MAP domain when handoffs are performed within the local domain and as such handoff performance may be improved and handoff latency reduced.
RQA forwards packets to MQA by changing RCoA to LCoA. Similarly, MQA forwards the packet to MN using CoA provided by AR to visitor MNs.
Specially, when a packet arrives at the MAP, the MAP selects the current LCoA of the destination MN from the mapping table and the packet is then routed to the MN.
The MAP uses MN' LCoA to identify which AR serves to the MN, and calculates the number of higher-mobility MNs and all MNs.
Two new IP addresses are established to employ HMIPv6: A Regional Care-of Address (RCoA) and a Local Care-of Address (LCoA).
