Background: Arthroscopic partial meniscectomy (APM) continues to be the popular treatment for meniscal tears, but recent randomized controlled trials have questioned its efficacy. To provide more evidence-based criteria for patient selection, we undertook this study to identify prognostic factors associated with clinical failure after APM for medial meniscus tears. Methods: Medical records of 160 patients followed up for at least 5 years after APM for medial meniscal tears were retrospectively reviewed. Demographic data (age, sex, and body mass index), radiographic variables (Kellgren-Lawrence [K-L] grade and hip-knee-ankle [HKA] angle), and clinical scores (International Knee Documentation Committee score, Tegner activity scale score, Lysholm score, and Knee injury and Osteoarthritis Outcome Score) were recorded. Clinical failure was defined as the need for an additional surgical procedure (arthroscopy, osteotomy, or arthroplasty) or the presence of intolerable pain. Survivorship analysis with clinical failure as an end point was performed using Kaplan-Meier survival curves. Factors related to clinical failure were analyzed using a Cox proportional hazard model. Cutoff values were determined using areas under receiver operating characteristic (ROC) curves. Radiographic progression of osteoarthritis was analyzed using the chi-square test, and serial changes of clinical scores were analyzed using a linear mixed model. Results: Clinical success rates were 95.7% at 5 years, 75.6% at 10 years, and 46.3% at 15 years. Age, HKA angle, and K-L grade (p = 0.01, p = 0.02, and p = 0.04, respectively) were found to be significant risk factors of clinical failure. Cutoff values at 10 years postoperatively as determined by ROC analysis were 50 years for age (sensitivity = 0.778, 1-specificity = 0.589), grade 2 for K-L grade (sensitivity = 0.778, 1-specificity = 0.109), and 5.5° for HKA angle (sensitivity = 0.667, 1-specificity = 0.258). In patients who had clinical success until 10 years after APM, radiological osteoarthritis progressed gradually. However, the clinical scores of patients who achieved clinical success did not decrease significantly over the 10-year follow-up. Conclusions The poor prognostic factors found to be related to clinical failure after APM for a medial meniscal tear were patient age (≥ 50 years), preoperative K-L grade (≥ grade 2), and preoperative HKA angle (≥ varus 5.5°).

Ceruminous glands are specialized sudoriferous glands located in the external auditory canal (EAC). Tumors originating from these ceruminous glands are rare lesions of EAC; in particular, syringocystadenoma papilliferum (SCAP) is an extremely rare ceruminous glands neoplasm to occur in the EAC. Although it is rare, the association of SCAP with tubular apocrine adenoma in the background of nevus sebaceous on the body, extremities, and scalp is well documented. In this article, we report on a 60-year-old male who presented a mass in EAC, which was surgically removed. The final diagnosis of SCAP was determined by histological analysis and the patient has been well without recurrence.

Background and Objectives: Transsphenoidal (TS) surgery for removal of pituitary lesions has become popular with improvements in diagnostic and treatment modalities, as well as endonasal and endoscopic methods, resulting in reduced complications. Rhinosinusitis (RS) is considered a risk factor for postoperative intracranial infections. Previously, we showed that concurrent TS surgery and endoscopic sinus surgery (ESS) yielded a favorable outcome in cases with pituitary lesions and RS. However, there seems to be a lack of consensus in performing simultaneous TS and ESS for patients with a pituitary lesion and RS. We would like to validate the feasibility of performing two operations concurrently.Subjects and Method We reviewed the medical records of 13 patients who underwent simultaneous TS surgery and ESS between 2007 and 2016. One patient underwent concurrent TS surgery and ESS twice due to the regrowth of pituitary macroadenoma and recurrence of RS. Results: There were only four minor nasal complications during the postoperative period, which were controlled with conservative treatment. Only one patient exhibited postoperative cerebrospinal fluid leakage and no patients experienced intracranial complications. Conclusion This study shows that it might be better to treat patients with pituitary lesion and RS simultaneously. Also, further studies with large cases would be necessary to manage these patients without intracranial complications.
