NTRODUCTION Tibial proximal osteotomy is one of the treatments for patients with knee compartment osteoarthritis. Studies showed 80% good prognosis in five years follow up after osteotomy. Almost always this method is used for pure medial knee compartment osteoarthritis that has a varus deformity. THE AIM of all methods is reforming varus deformity and lower limb alignment to gain 3 to 5 degree...

Abstract Aim To compare the robotic-assisted unicompartmental knee arthroplasty (UKA) with conventional UKA. Method We systematically searched on four databases till September 2021. The outcomes were pooled as mean difference (MD) or standardized (SMD) risk ratio (RR), and 95% confidence interval. used RevMan to perform analysis. Results There 22 included studies. no significant differences bet...

The demand for revision knee arthroplasty is increasing daily with the increase in number of patients undergoing primary arthroplasty. aim therefore should be restoration mechanical alignment limb joint line and biomechanics these goals accomplished least possible use constrained implants which otherwise depends on degree bone defects integrity collateral ligaments. We have hereby reported a ca...

OBJECTIVES Osteophytes are thought to stabilize an osteoarthritic joint, thereby preventing structural progression. Meagre longitudinal data suggest, however, that they are associated with an increased risk of structural progression. Our objective was to evaluate the effect of osteophyte size on radiographic progression in osteoarthritis (OA). METHODS Using data from a natural history study o...

The limb-driving force mutation of the modular combination parallel manipulator (MCPM) affects alignment process optical axis. In this paper, a novel optimization method based on penalty term is proposed to solve problem driving mutation. kinematics and dynamics models are established using modularization idea, reducing complexity modeling process, verified co-simulation. Moreover, particle swa...

Medial patellofemoral ligament (MPFL) reconstruction has been shown to be a successful treatment for patients with recurrent patellar instability. The purpose of this study is compare radiographic parameters prior and following an MPFL femoral tunnel fixation in the skeletally immature patient investigate potential effects on physic future growth. Skeletally undergoing isolated were retrospecti...

OBJECTIVE To determine whether knee arthrodesis with simultaneous lengthening using the Ilizarov method for a nonreconstructable knee joint with bone loss and infection is a successful salvage procedure. DESIGN Retrospective review of patients. SETTING University hospital-based orthopaedic practice. PATIENTS From 1999 to 2001, 4 consecutive patients with a nonreconstructable knee joint, b...

OBJECTIVE To compare the results obtained with computer assisted surgery with conventional techniques and evaluate the influence of navigation at different levels of preoperative deformity. MATERIAL AL METHOD A retrospective study was conducted on 100 cases with primary total knee arthroplasty performed with conventional or computer assisted surgery. A comparison was made of the post-operativ...

Minimally invasive and robot-assisted procedures have potential advantages when used for total knee arthroplasty (TKA). The purpose of this cadaveric study was to examine whether robot-assisted minimally invasive procedures improve TKA alignment after modifying the robotic techniques and instruments. Total knee arthroplasties were performed on 10 pairs of fresh cadaveric femora. Ten knees were ...

BACKGROUND Accurate femoral rotational alignment is of vital importance for successful total knee arthroplasty (TKA). The value of computer-assisted surgery TKA (CAS-TKA) in increasing the accuracy of femoral rotational alignment remains controversial. We hypothesize that outcomes are related to the severity of preoperative varus and valgus deformity and that CAS-TKA may be beneficial under cer...
