BACKGROUND AND OBJECTIVES The Copenhagen Hip And Groin Outcome Score (HAGOS) was developed to assess disease-specific consequences in young to middle-aged, physically active hip and/or groin patients. The study aimed to determine validity and reliability of the Dutch version of the HAGOS (HAGOS-NL) for middle-aged patients with hip complaints. DESIGN AND METHODS To assess validity, 117 partic...

BACKGROUND There is no baseline activity scale yet validated in pediatric patients. The Marx and Tegner scales have been validated in adult patients only. The Tegner scale involves questions not pertinent to children, such as their work activity. The Marx scale is simple, and all its questions can be related to athletic activities. HYPOTHESIS The Marx scale is reliable for use in a pediatric ...

BACKGROUND The different functions of the two anterior cruciate ligament (ACL) bundles have increased interest in tears of only one of these two bundles. The purpose of this study was to assess the outcome of selective reconstruction of an injured bundle of isolated anteromedial bundle (AMB) or posterolateral bundle (PLB) tears. METHODS Consecutive series of 147 ACL reconstructions was prospe...

PURPOSE In anterior cruciate ligament (ACL) injury, conventional adult reconstruction techniques have to face the potential risk of growth disturbance or angular deformities in skeletally immature patients. The aim of this study was to evaluate the clinical outcomes of ACL reconstruction by conventional transphyseal tunnel technique. MATERIALS AND METHODS On a retrospective basis, we reviewed...

BACKGROUND Medial patellofemoral ligament (MPFL) reconstruction has become an accepted technique to treat patellofemoral instability, and numerous surgical techniques have been described to reconstruct the MPFL. We describe a MPFL reconstruction procedure where bone-fascia tunnel fixation occurs at the medial margin of the patella for recurrent patellar dislocation. OBJECTIVE MPFL reconstruct...

BACKGROUND AND PURPOSE Autologous osteochondral transplantation (OCT) is an established method of treating articular cartilage defects in the knee. However, the potential for donor site morbidity remains a concern. Both the restoration of the original cartilage defect and the evolution of the donor site defects can be evaluated by bone scintigraphy. Thus, we performed a prospective bone scintig...

BACKGROUND Previous studies have reported varying return-to-sport protocols after knee cartilage restoration procedures. PURPOSE To (1) evaluate the time for return to sport in athletes with an isolated chondral injury who underwent an accelerated return-to-sport protocol after osteochondral autograft plug transfer (OAT) and (2) evaluate clinical outcomes to assess for any consequences from t...

OBJECTIVE To analyze the incidence of ACL and meniscal injuries in a population of recreational and elite athletes from Brazil and the relation of these injuries with their sports activities. METHODS This was a prospective observational study of 240 patients with ACL and/or meniscal injuries submitted to surgical treatment. Data of patients and sport modality, as well as Tegner score were reg...

PURPOSE To translate and cross-culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) into simplified Chinese [ACL-RSI (Cn)]. METHOD In this diagnostic study, the translation, cross-culturally adaptation, and validation of the ACL-RSI was performed according to international guidelines. A total of 112 patients with ACL reconstruction participated in this study....

BACKGROUND The meniscus plays a key role in the functioning of the knee. At the present time, meniscal repair has becomes the main treatment for meniscal tear. Compared to open surgery, arthroscopic meniscal repair has become popular because of shorter time need for the operation, the smaller wound, and better accessibility to the tear portion, which is particularly difficult during open surger...
