Background: Patellofemoral arthritis is a common cause of anterior knee pain and limits flexion-related activities of daily living and exercise. While frequently present in bicompartmental and tricompartmental osteoarthritis, patellofemoral arthritis can occur in isolation. Patellofemoral arthroplasty as a treatment option is gaining in popularity, especially with new implant designs. We report a case in which new inlay implants were used to resurface the patellofemoral joint in a patient with contralateral compromise secondary to a previous below-knee amputation...

OBJECTIVE: To determine whether baseline quadriceps weakness predicts cartilage loss assessed on magnetic resonance imaging (MRI). METHODS: Subjects aged 40-79 with knee pain (n = 163) were recruited from a random population sample and examined for quadriceps weakness with manual isometric strength testing, using a 3-point scoring system (0 = poor resistance, 1 = moderate resistance, 2 = full resistance), which was dichotomized as normal (grade 2) versus weak (grade 0/1)...

Osteoarthritis, one of the most common pathological conditions observed in human skeletal remains, is traditionally thought to only affect the structures within the joint capsule. We examined the osteoarthritic distal femora of an individual from Ancient North China, ca. 475-221 BCE. The standard signs of osteoarthritis, marginal lipping and extensive eburnation, were observed in the patellofemoral compartment of the knee joint. In addition however were bilateral pressure-caused fossae on the extra-articular anterior surfaces of the distal femora 10 mm proximal to the large osteophytes at the apex of the patellar surfaces...

BACKGROUND: Medial unicompartmental knee arthroplasty (UKA) has been a successful option for treatment of arthritis in patients with a healthy lateral compartment. However, lateral UKA is less common and results are less consistent. The purpose of this study is to compare progression of radiographically evident osteoarthritis in unoperated compartments during 5 years after lateral and medial UKA. METHODS: We undertook serial radiographic evaluation of 20 lateral and 114 medial UKA performed by the senior author during calendar years 2007-2008...

As a common disease of knee joint disease, the diagnosis and treatment of patellofemoral arthritis has not clear clinical consensus at present, conservative treatment only has a certain value for the disease with early stage and single disease. With the continuous improvement of understanding of pathogenesis and advancement of surgical techniques, minimally invasive and joint replacement technology has been rapid development, more and more alternative treatment options could be chosen. Technique of osteotomy of tibial tuberosity and removal of patella at the early stage were seldom used...

This article compares the long-term outcomes of closing-wedge osteotomy (CWO) and opening-wedge osteotomy (OWO) in the treatment of unicompartmental medial osteoarthritis with varus deformity. This study included 79 patients who underwent high tibial osteotomy (HTO) between 2002 and 2008. Pre- and postoperative radiography and computed tomography were used to evaluate the posterior tibial slope, the patellar height, the tibiofemoral angle, and the lateral and medial tibiofemoral joint space. Pre- and postoperative severity of arthritis was assessed with the Kellgren-Lawrence grading system...

Background: Anterior knee pain following total knee arthroplasty (TKA) remains one of the important reasons for patient dissatisfaction. The management of patellofemoral joint is controversial and a decision whether to resurface the patella or not, is important. The present study compares the clinical and radiological outcomes between patellar resurfacing and nonresurfacing in patients undergoing bilateral TKA. Materials and Methods: This is a prospective comparative study with 60 patients undergoing bilateral simultaneous TKA (120 knees) with posterior stabilized Hi flex fixed bearing knee (Zimmer, Warsaw, Indiana), by two surgeons...

Recurrent patellar dislocation is a disabling condition, which can lead to articular cartilage injuries, osteochondral fractures, recurrent instability, pain, decreased activity and patellofemoral osteoarthritis. Trochlear dysplasia represents an important component of patellar dislocation.Imaging provides an objective basis for the morphological abnormalities and thus allows determination of the surgical strategy according to the concept of 'à la carte' surgery.The main surgical techniques of trochleoplasty are the sulcus deepening trochleoplasty, the 'Bereiter' trochleoplasty and the recession trochleoplasty...

Distal femoral varus osteotomy is a well-described treatment option for patients with valgus malalignment associated with a variety of underlying conditions. This procedure may be the definitive treatment option in active patients with isolated lateral compartment osteoarthritis or posttraumatic arthritis. It may be a useful concomitant procedure in young patients with lateral meniscus deficiency, focal chondral defects, chronic medial collateral ligament insufficiency, and/or patellofemoral instability. Distal femoral varus osteotomy can be performed with medial closing wedge or lateral opening wedge techniques...

Isolated patellofemoral arthritis (IPA) is a debilitating condition characterised by a loss of articular cartilage on the patella facets, the trochlear groove or both. By definition, patients with IPA must have normal cartilage in the tibiofemoral compartments of their knee. It is therefore logical to pursue arthroplasty which corrects the abnormality while sparing healthy bone and preserving the knee's native kinematics, which is the premise underpinning patellofemoral arthroplasty (PFA). However, its use remains controversial, with many surgeons still favouring total knee replacement (TKR) in these patients...

RATIONALE: The fabella is a normal structure, but is occasionally reported to cause posterior knee pain. The aim of this study was to present fabella syndrome after high tibial osteotomy. PATIENT CONCERNS: A 55-year-old female patient was admitted to the hospital due to about 1 year and 8 months of left knee pain. Sclerosis was observed in the anterior margin of the fabella in the preoperative magnetic resonance (MR) T2 image, and reactive bone marrow was found and was considered to be due to degeneration of the distal femur...

The shifting demographics of patients with localized knee arthritis, including younger, more active patients, is a chief motivation for mounting interest in tissue preserving surgical substitutes for total knee arthroplasty (TKA). Unlinked, modular bi-compartmental knee arthroplasty (MBKA) is an emerging knee-resurfacing approach that provides a conservative alternative to TKA. Arthritis involving both patellofemoral and either medial or lateral tibiofemoral compartments, with no significant deformity or bone deficiency, preserved motion, and intact cruciate ligaments, can be effectively managed with MBKA...
