The Large Focal Isolated Chondral Lesion
J Knee Surg DOI: 10.1055/s-0041-1735278Focal chondral defects (FCDs) of the knee can be a debilitating condition that can clinically translate into pain and dysfunction in young patients with high activity demands. Both the understanding of the etiology of FCDs and the surgical management of these chondral defects has exponentially grown in recent years. This is reflected by the number of surgical procedures performed for FCDs, which is now approximately 200,000 annually. This fact is also apparent in the wide variety of available surgical approaches to FCDs. Although simple arthroscopic debridement or microfracture are usually the first line of treatment for smaller lesions, chondral lesions that involve a larger area or depth require restorative procedures such as osteochondral allograft transplantation or other cell-based techniques. Given the prevalence of FCDs and the increased attention on treating these lesions, a comprehensive understanding of management from diagnosis to rehabilitation is imperative for the treating surgeon. This narrative review aims to describe current concepts in the treatment of large FCDs through providing an algorithmic approach to selecting interventions to address these lesions as well as the reported outcomes in the literature.

Conclusions: The identification of preanalytical factors that may negatively impact TDM is critical. Developing workflows that can standardize TDM practices, align appropriate timing and blood collection techniques, and specimen processing will eliminate errors.
In conclusion, MK-801 induced antinociception effects for thermal stimuli in rats that were consistent with the decreased pain sensitivity observed in schizophrenia patients. Additionally, the amplified biphasic response exhibited by the MK-801 group in the formalin-induced spontaneous nociception test affirms the suitability of the test as a model of acute to delayed pain transition.
In conclusion, naringenin could be a promising antinociceptive agent acting through opioid receptors and L-arginine/NO/cGMP/KATP channel pathway.
ConclusionsRM-1929 photoimmunotherapy showed a manageable safety profile in rHNSCC. Tumor response in these heavily pre-treated patients was clinically meaningful and warrants further investigation.Clinical trial registrationThe trial was registered with the Japanese registry of clinical trials as jRCT2031200133.
Deep brain stimulation (DBS) is an effective surgical treatment for patients with various neurological and psychiatric disorders. Clinical improvements rely on careful patient selection and accurate electrode placement. A common method for target localization is intraoperative microelectrode recording (MER). To facilitate MER, DBS surgery is traditionally performed under local or regional anesthesia. However, sedation or general anesthesia is sometimes needed for patients who are unable to tolerate the procedure fully awake because of severe motor symptoms, psychological distress, pain, or other forms of discomfort. The ef...
Conclusions: Of opioid-naive geriatric patients who underwent surgery for DSD, 0.3% developed chronic, continuous opioid use. Preoperative opioid use was the strongest predictor of prolonged utilization, which may represent suboptimal use of nonopioid alternatives, pre-existing opioid use disorders, delayed referral for surgical evaluation, or over-prescription of opioids for noncancer pain.
AbstractOsteochondral lesions (OCLs) of the talar dome consist of a multifactorial pathology of the articular cartilage and subchondral bone and can result in persistent ankle pain and osteoarthritis (OA). Along with a physical examination and clinical history, an imaging evaluation plays a pivotal role in the diagnosis of these lesions and is fundamental for making treatment decisions and determining prognosis by providing information regarding the size, location, and cartilage and subchondral bone statuses as well as associated lesions and degenerative changes. Multiple surgical techniques for OCLs of the talar dome have...
ConclusionsPreoperative hip aspiration showed good diagnostic performance in diagnosing PJI compared with MSIS criteria as a standard of reference. But a negative result from aspirate could not rule out PJI. Based on our findings, hip aspiration is an essential test for treatment planning in patients with pain after hip arthroplasty.
AbstractObjectiveTo assess the relationship between low- and high-grade subchondral insufficiency fracture of the knee (SIFK) and meniscal tear/type/location, severity of meniscal extrusion, grade of chondrosis, and extent of surrounding edema-like marrow signal intensity.Materials and methodsOur retrospective study included 219 patients with knee pain and SIFK seen on MRI. SIFK lesions were categorized from grade 1 to 4 with a low grade (1 and 2) vs high grade (3 and 4) distinction. Associations between SIFK grade, location, lesion dimensions, edema-like marrow signal intensity, incidence of meniscal tears/type/location, ...
ConclusionsIn the setting of prior IVF therapy, imaging features of an irregularly marginated, deep subcutaneous gluteal lesion with inflammatory soft tissue changes surrounding solitary or multifocal areas of loculated fat signal may be seen as an inflammatory response to previous inadvertent subcutaneous injection(s).
