Patellar instability is a known but catastrophic complication after total knee arthroplasty (TKA). The occurrence of bilateral dislocation of the patella after TKA is exceedingly rare. It may present as anterior knee pain, and diagnosis can easily be made clinically or by plain radiographs. Early diagnosis with surgical realignment and repair of the extensor mechanism can provide good outcomes after this complication.

BACKGROUND: A tourniquet is usually used during anterior ankle arthroscopy to allow for improved visibility and reduced operation time. However, this has not been demonstrated to be true in clinical studies on knee arthroscopy, while limited tourniquet time has been described as a possible factor to lower the complication rate of ankle arthroscopy. The purpose of this randomized controlled trial was to examine the effect of tourniquet use on arthroscopic visualization, operative time, postoperative intra-articular bleeding, postoperative pain scores, and outcome of anterior ankle arthroscopy...

A pediatric patient with critical limb ischemia secondary to antiphospholipid syndrome (APS) is reported. A 14-year-old male underwent extensive evaluation for worsening right lower extremity pain and ulcerative lesions of his right foot. He was discovered to have proximal occlusion of the superficial femoral artery (SFA), the distal popliteal artery, the anterior tibial artery at the mid-calf, and the posterior tibial artery at the ankle. Laboratory analysis revealed a diagnosis of APS, and he underwent a common femoral artery to above-knee-popliteal artery bypass with reversed greater saphenous graft...

PURPOSE: Only few long-term data on ligament-balanced cruciate-retaining total knee arthroplasty (CR TKA) are currently available. Either a mobile- or fixed-bearing insert can be chosen, which showed good mid-term outcome and few complications and revisions. This multi-centre retrospective cross-sectional cohort study investigated the 12-year results of primary TKA using a balancing gap technique and compared survival and clinical outcome between fixed and mobile inserts. METHODS: In this retrospective cross-sectional cohort study, 557 cases of three clinics (2 Swiss, 1 Dutch) operated between 1998 and 2003 with the first series of a TKA implanted with a balanced gap technique (433 (77...

Objective. : It has been suggested that repeated overload might sensitize nociceptors, causing local hyperalgesia in patients with patellofemoral pain (PFP). This might also lead to generalized hyperalgesia, indicative of altered central pain processing. This study aimed to investigate differences in pressure pain threshold (PPT) as a measure of pressure hyperalgesia between patients with PFP and healthy controls and in predefined subgroups and to study associations between PPT and patient characteristics...

PURPOSE: There exist limited options for treatment of patients with combined medial compartment arthritis and anterior cruciate ligament (ACL) deficiency. Ideal treatment is one that offers lasting relief of symptoms not compromising any future surgery. Unicompartmental knee replacement has shown consistently good results in the relatively young and active population, but there is a high reported incidence of failure up to 20%, if performed in ACL-deficient knees. One of the recognized treatment modality is combined ACL reconstruction and unicompartmental arthroplasty...

INTRODUCTION: Patella-post impingement (PPI), contact of the patellar component with the tibial post, occurs during deep knee flexion after posterior stabilized total knee arthroplasty (TKA). PPI can cause anterior knee pain, increased patellar pressure, wear of the polyethylene patellar component and tibial post, and poor range of motion. There have been no reports on the relationship between PPI and tibial post design. The aim of this study was to compare different tibial post designs with regard to PPI incidence...

Knee joint pain is a common symptom in obese individuals and walking is often prescribed as part of management programs. Past studies in obese individuals have focused on standing alignment and kinematics in the sagittal and coronal planes. Investigation of 6 degree-of-freedom (6DOF) knee joint kinematics during standing and gait is important to thoroughly understand knee function in obese individuals with knee pain. This study aimed to investigate the 6DOF knee joint kinematics in standing and during gait in obese patients using a validated fluoroscopic imaging system...

PURPOSE: Ramp lesions are common in ACL deficient knees. Their diagnosis is difficult and, therefore, they may be underestimated. So far, no study analyzed their prevalence in a pediatric population. The diagnosis of these Ramp lesions is of major clinical relevance because of a frequent misestimating and technic difficulties. Ramp lesions might be associated with residual knee pain and instability after ACL reconstruction. The aim of this study was to evaluate the prevalence of ramp lesions explored through a systematic intercondylar and posteromedial arthroscopic approach during an ACL reconstruction in a pediatric and adolescent population...
