A recent study conducted at Seoul National University in South Korea examined the impact of referencing systems on the selection of implant size, position, and gap balance in total knee arthroplasty (TKA). The study compared the outcomes of 270 patients who underwent TKA using either an anterior referencing (AR) or posterior referencing (PR) system. The results showed that the referencing system did not significantly affect implant size or alignment, but there were differences in fit and incidence of anterior notching between the two groups. Overall, the study suggests that the differences observed are likely due to specific implant designs and surgical techniques rather than the referencing system used. [Extracted from the article]

A recent study conducted by researchers at Ajou University School of Medicine in South Korea examined the incidence and risk factors for wound revision after surgical treatment of spinal metastasis. The study utilized the comprehensive Korean National Health Insurance Service database and reviewed a cohort of 3001 patients who underwent one of five surgical treatments for newly diagnosed spinal metastasis between 2009 and 2017. The researchers found that surgical method and Charlson comorbidity index were significantly associated with the risk of wound revision. The study provides valuable insights into the factors that contribute to wound complications in patients undergoing surgery for metastatic spine tumors. [Extracted from the article]

A new study conducted by researchers at the Catholic University of Korea examined the effects of atelocollagen insertion in the bone-tendon interface of the repaired tendon after arthroscopic rotator cuff repair for high-grade partial articular supraspinatus tendon avulsion (PASTA) lesions. The study compared the clinical and radiological outcomes of atelocollagen-inserted rotator cuff repair and atelocollagen-noninserted rotator cuff repair in patients with PASTA lesions. The results showed that the addition of atelocollagen did not significantly improve outcome scores, but there was slightly greater flexion and abduction at the final follow-up, as well as less residual discomfort.

A recent study conducted by researchers at the Catholic University of Korea examined the relationship between central sensitization and neuropathic pain in patients who underwent total knee arthroplasty (TKA). The study included 316 Asian patients with end-stage osteoarthritis of the knee. The researchers found that patients with both central sensitization and neuropathic pain reported inferior patient-reported outcome measures (PROMs) compared to patients with either condition alone or without either condition. The study suggests that both central sensitization and neuropathic pain contribute to poorer outcomes following TKA. [Extracted from the article]

A study conducted at Seoul National University Hospital in South Korea has presented a modified technique for correcting moderate hallux valgus deformity, a condition characterized by the misalignment of the big toe. The researchers compared the outcomes of 68 patients who underwent the modified technique with 22 patients who underwent the conventional technique. Both groups showed significant correction of the deformity, but the modified technique resulted in a greater amount of correction. Importantly, there were no complications observed in either group, suggesting that the modified technique is effective and safe for treating this condition. [Extracted from the article]
