Objectives: Osteochondritis dissecans can result in significant limitations in activity, pain, and early osteoarthritis. There are various treatment modalities to address these defects. The purpose of this study was to provide a qualitative summary of the various treatment options for unstable osteochondritis dissecans in the knee.

The purpose of this study was to compare differences in clinical and functional outcomes in patients treated with OCA for osteochondral defects compared with isolated chondral pathology.
Methods: A retrospective review identified patients who underwent OCA transplantation and grouped them into osteochondral or isolated chondral pathology.
»: Distal hamstring muscle injuries, although relatively uncommon, can potentially lead to substantial morbidity in athletes; prolonged rehabilitation times and high rates of reoccurrence have been documented.
»: Overall, magnetic resonance imaging is considered the "gold standard" for evaluation of hamstring injuries because it allows assessment for concomitant pathology and can clarify return-to-sport timelines.
»: Complete tears of the distal biceps femoris and semimembranosus muscles respond well to surgical repair, whereas complete tears of the distal semitendinosus can be successfully treated nonoperatively or with surgical resection.
Background: Articular cartilage pathology can result from a spectrum of origins, including trauma, osteochondritis dissecans, avascular necrosis, or degenerative joint disease.
Purpose: To compare the differences in clinical and patient-reported outcomes after autologous chondrocyte implantation (ACI) versus osteochondral allograft transplantation (OCA) in patients with focal articular cartilage defects without underlying bone loss.
Study Design: Cohort study; Level of evidence, 3.
Background: A large number of systematic reviews and meta-analyses regarding the meniscus have been published.
Purpose: To provide a qualitative summary of the published systematic reviews and meta-analyses regarding the meniscus.
Study Design: Systematic review; Level of evidence, 4.
Background: Repair of a meniscal tear is indicated in certain conditions. Despite extensive research on the biomechanics of various repair methods, there has been minimal investigation of whether the suture material influences the meniscal-suture construct. The purpose of this study was to compare the biomechanical properties of nine different suture materials under cyclic and load-to-failure conditions.

The Walch classification is commonly used to categorize glenoid bone loss into several different types. Preoperative CT can assist in identifying the type and extent of bone loss for development of the appropriate treatment plan.

In the lower extremity, compartment syndrome has been associated with fractures of the tibial plateau, shaft, and plafond. The patient was an 89-year-old male driver involved in a T-bone type motor vehicle accident. He sustained a closed transverse fibular shaft fracture and initially had fullness in his anterior/lateral compartments but no pain with passive and active range of motion of his ankle.

In this article, we discuss the low postoperative complication rate in a series of 3100 navigated TKAs and the overall complication rate in a systematic analysis of the literature.
Methods: Three thousand one hundred consecutive patients with navigated TKAs from 2001-2016 were retrospectively evaluated for complications specific to navigation.

The Internet has become a major source for obtaining health-related information. This study assesses and compares the quality of information available online for shoulder replacement using medical (total shoulder arthroplasty [TSA]) and nontechnical (shoulder replacement [SR]) terminology. Three evaluators reviewed 90 websites for each search term across 3 search engines (Google, Yahoo, and Bing).

This case report describes a patient treated with rhBMP-2 for an atrophic delayed union of a clavicular fracture who subsequently developed a profound motor and sensory brachial plexopathy.
Conclusion: Use of rhBMP-2 near peripheral nerves may cause neuropathy.
