Do we need to restore patellar thickness after total knee arthroplasty with patellar resurfacing?
PurposeThe aim of this study was to investigate whether increased patellar thickness after resurfacing decreased knee flexion angle and had any...

Patellar shift ratio (PSR) is the optimal measurement for characterising lateral patellar shift and a reliable predictor of recurrent patellar dislocation
PurposeTo propose a new measurement, the patellar shift ratio (PSR), for characterising lateral patellar shift; to determine its diagnostic accuracy...

Preoperative patellar bone marrow lesions with full thickness cartilage defects correlate with residual anterior knee pain in total knee arthroplasty without patellar resurfacing
PurposeResidual anterior knee pain is one of the most common problems after total knee arthroplasty (TKA). However, the contributing factors...

Effect of total knee arthroplasty for valgus knee correction on clinical outcome and patellar position
PurposeThe purpose was to investigate the effect of different degrees of valgus deformity correction on patellar position and clinical outcome in...

Reconstruction of the medial patellofemoral ligament with nonresorbable suture tape normalizes patellar maltracking independent of patella-side fixation technique
PurposePatellar maltracking caused by a rupture of the medial patellofemoral ligament (MPFL) can be improved by MPFL reconstruction (MPFL-R) with a...

Systematic lateral retinacular release does not reduce anterior knee pain after total knee arthroplasty with patellar resurfacing
PurposeThe aim of this study was to assess the effect of systematic lateral retinacular release (LRR) on anterior knee pain (AKP), as well as its...

The remaining parameters of patellar instability could be affected for osteoarthritic change after medial patellofemoral ligament reconstruction with or without anteromedialization of the tibial tubercle osteotomy for patellar instability: a retrospective cohort study
BackgroundIn literature, studies evaluating the factors associated the postoperative progression of patellofemoral (PF) osteoarthritis (OA) following...

Elevated hip adduction angles and abduction moments in the gait of adolescents with recurrent patellar dislocation
IntroductionImpaired hip kinematics and kinetics may incite patellar instability. This study tested the hypothesis that hip adduction and internal...

Electrophysiological and pathological changes in the vastus medialis and vastus lateralis muscles after early patellar reduction and nerve growth factor injection in rabbits with patellar dislocation
BackgroundPatellar dislocation can cause a series of changes in the trochlear groove and patella. However, the influence of patellar dislocation on...

Lateral approach total knee arthroplasty achieves equivalent patellar tracking in severe valgus deformity compared to mild valgus deformity
PurposePatellar tracking problems represent 2–10% of complications of total knee arthroplasties (TKA) in valgus knees. However, there are no studies...
