OBJECTIVES Posterior condylar offset (PCO) and posterior tibial slope (PTS) are critical factors in total knee arthroplasty (TKA). A computational simulation was performed to evaluate the biomechanical effect of PCO and PTS on cruciate retaining TKA. METHODS We generated a subject-specific computational model followed by the development of ± 1 mm, ± 2 mm and ± 3 mm PCO models in the posterior...

Robotic assisted total knee arthroplasty is one the recent advance to improve its outcome especially address issue of precision. Longetivity TKA primarily depends on proper implant alignment. The Aim this study compare precision robotic with ideally planned mechanical parameters in TKA. A 50 patients were included retrospectively study. Patient’s post operative femorotibial angle (mFTA), Latera...

BACKGROUND Accelerated knee osteoarthritis may be a unique subset of knee osteoarthritis, which is associated with greater knee pain and disability. Identifying risk factors for accelerated knee osteoarthritis is vital to recognizing people who will develop accelerated knee osteoarthritis and initiating early interventions. The geometry of an articular surface (e.g., coronal tibial slope), whic...

Debate has raged over whether a cruciate retaining (CR) or a posterior stabilised (PS) total knee replacement (TKR) provides a better range of movement (ROM) for patients. Various sub-sets of CR design are frequently lumped together when comparing outcomes. Additionally, multiple factors have been proven to influence the rate of manipulation under anaesthetic (MUA) following TKR. The purpose of...

OBJECTIVE The geometry of the tibial plateau has a direct influence on the translation and the screw home biomechanics of the tibiofemoral joint. Little information on the relationship between the tibial slope and meniscal lesions is available. The objective of this retrospective study was to examine the effect of the tibial slope on the medial and lateral meniscus lesions in patients with inta...

We have compared a new technique of computer-assisted knee arthroplasty with the current conventional jig-based technique in 70 patients randomly allocated to receive either of the methods. Post-operative CT was performed according to the Perth CT Knee Arthroplasty protocol and pre- and post-operative Maquet views of the limb were taken. Intra-operative and peri-operative morbidity data were co...

Abstract Background Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in posterior slope (PTS) may occur. Several factors cause PTS alterations after HTO; however, research on sagittal-plane inclination (SPOI) relation to sparse. The purpose this study was evaluate whether SPOI affects HTO. ...

Objectives: To evaluate the effect of amount correction on postoperative changes in PTS (posterior tibial slope), PH (patellar height), and clinical outcomes following biplanar OWHTO (open-wedge high osteotomy). Method: This study included 79 knees (32 left 47 right) patients (mean age 60.28 ± 4.2 years, 24 males, 55 females) with varus malalignment symptomatic isolated medial joint osteoarthri...
