OBJECTIVE To assess the clinical outcome of patients treated with autologous chondrocyte implantation using ChondroCelect in daily practice. METHODS The study is a cross-sectional analysis of an open-label, noninterventional cohort. The setting was a compassionate use program, involving 43 orthopaedic centers in 7 European countries. The participants were patients treated with ChondroCelect b...

OBJECTIVES Sustained intra-articular delivery of pharmacological agents is an attractive modality but requires use of a safe carrier that would not induce cartilage damage or fibrosis. Collagen scaffolds are widely available and could be used intra-articularly, but no investigation has looked at the safety of collagen scaffolds within synovial joints. The aim of this study was to determine the ...

Rotation errors of the femoral component are held responsible for occurrences such as instability in flexion and midflexion, patellar maltracking, and arthrofibrosis following total knee arthroplasty. However, in many cases, the epicondylar axis cannot be reliably identified due to bone defects or metal artifacts on computed tomography, so alternative landmarks are necessary to evaluate the fem...

The number of primary anterior cruciate ligament (ACL) tears is rapidly increasing. In patients who wish to return to their preoperative level of function, specifically as it pertains to participation in sports, the gold standard of treatment following an ACL tear remains an anterior cruciate ligament (ACL) reconstruction. Despite a majority of good/excellent results following primary ACL recon...

Cost-containment strategies are of increasing importance in total knee arthroplasty (TKA). Obtaining immediate postoperative radiographs following primary TKA is common practice, but their usefulness is controversial. The goal of this study was to evaluate the effect of immediate postoperative radiographs on reoperation within 60 days, assess film quality, and determine the cost associated with...

PURPOSE To analyze the causes and types of complications after unicompartmental knee arthroplasty (UKA) and determine proper prevention and treatment methods. MATERIALS AND METHODS A total of 1,576 UKAs were performed for osteoarthritis of the knee from January 2002 to December 2014 at one institution. We analyzed complications after UKA retrospectively and investigated proper methods of trea...

Revision total knee arthroplasty (TKA) is becoming increasingly common as the population ages and the number of existing primary TKAs continues to increase. Revision TKA systems use a greater range of component modularity than primary TKA systems, including stems, augments, and varying levels of constraint. The purpose of this study was to retrospectively review the authors' institution's use o...

PURPOSE We report an easy-to-use 4-portal technique for arthroscopic treatment of intercondylar eminence fractures and compare results of 2 groups of cases, adolescents and adults, and 2 types of internal fixation, sutures and screws. TYPE OF STUDY Surgical technique and retrospective study. METHODS The study was carried on 2 groups of patients, adolescents and adults, with intercondylar em...

The response of living tissue to trauma—chemical, thermal, or mechanical—is of prime concern to the physician . This is particularly true in surgery . The body, not the surgeon, repairs wounds . The surgeon is responsible for providng optimum environmental circumstances for wound healing consistent with the surgical problems he faces . Gentleness in the handling of tissues is the first surgical...

BACKGROUND The healing potential of damaged articular cartilage is limited. The NeoCart is a tissue-engineered collagen matrix seeded with autogenous chondrocytes designed for the repair of hyaline articular cartilage. HYPOTHESIS The NeoCart implant is well tolerated in the human knee. STUDY DESIGN Case series; Level of evidence, 4. METHODS Eight patients (treatment group) with full-thick...
