Traumatic and degenerative cartilage lesions: arthroscopic differentiation using near-infrared spectroscopy (NIRS).
Cartilage lesions or defects are the most common finding during knee arthroscopy. During arthroscopy, it is often difficult to differentiate between degenerative and traumatic cartilage lesions. The study aimed to determine the impact of near-infrared spectroscopy (NIRS) on the distinction between traumatic and degenerative cartilage lesions in the medial femoral condyle (MFC). It was hypothesized that NIRS as able to distinguish between traumatic and degenerative cartilage lesions. ⋯ After an injury, cartilage has a normal or nearly normal absorbance on near-infrared-light. Thus, it is possible to distinguish intraoperatively between traumatic and degenerative lesions. In addition, our results demonstrate that evaluating cartilage with NIRS is a dependable method for improving the diagnosis of significant chondral lesions.

Intramedullary nail versus extramedullary plate fixation for unstable intertrochanteric fractures: decision analysis.
The best options of internal fixation for unstable intertrochanteric femoral fractures in elderly osteoporotic patients remain controversial. We determined whether intramedullary nail or extramedullary plate provides better treatment for unstable intertrochanteric fractures using a decision analysis tool that considers quality of life. ⋯ In terms of quality of life, the decision analysis model showed that intramedullary nailing was more beneficial for patients with an unstable intertrochanteric fracture.

Return to play following ACL reconstruction: survey among experienced arthroscopic surgeons (AGA instructors).
There is a lack of consensus regarding appropriate criteria attesting patient's unrestricted sports activities after ACL reconstruction. The purpose of this study was to perform a survey among experienced arthroscopic surgeons regarding their return to play guidelines in these patients. ⋯ In conclusion, the majority of surgeons do not consider muscle function, jump tests, alignment tests, and proprioception as relevant return to sports criterion. However, these are two crucial parameters for return to sports.

Randomized Controlled Trial Comparative StudyThe effects of corticosteroid injection versus local anesthetic injection in the treatment of lateral epicondylitis: a randomized single-blinded clinical trial.
This study seeks to compare two treatment methods of lateral epicondylitis: corticosteroid injection (CSI) and a local anesthetic injection (LAI). ⋯ For lateral epicondylitis, CSI has the best short-term treatment results yet the highest recurrent rates. The combination of CSI with other treatment option or with a change in injection technique from single injection to peppering injection may be promising.

Comparative StudyJoint line changes in cruciate-retaining versus posterior-stabilized computer-navigated total knee arthroplasty.
This study compared joint line changes and functional outcomes between cruciate-retaining (CR) and posterior-stabilized (PS) computer-navigated total knee arthroplasties (TKAs). With the increased precision offered by computer navigation, we hypothesized that there should be minimal differences in the joint line changes between the groups and thus no significant differences in the clinical outcomes. ⋯ III.
