The Knee Surgery

Periprosthetic joint infection (PJI) |  is one of the most feared and distressing complications following total knee arthroplasty (TKA). Despite efforts to prevent infection, literature reports an incidence rate of 0.2–1.5% after primary TKA and approximately 0.6–4% after revision TKA. Once an infection occurs, the prognosis deteriorates significantly, often preventing a full return to the previous state. Patients frequently require multiple revision surgeries and prolonged antibiotic therapy, leading to substantial physical and financial burdens for both patients and healthcare providers. Therefore, a thorough preoperative evaluation, meticulous surgical planning, and adherence to treatment principles are essential to minimize infection risks. This article provides a literature review on methods to prevent infections following TKA.

ACL reconstruction with Remnant preserving technique:  Treatment for High grade Anterior Cruciate Ligament (ACL) Partial Tears Treatment selection is crucial for anterior cruciate ligament (ACL) partial tears, to achieve favorable long-term outcomes.   I had the opportunity to present on this topic at ACL Symposium in Korea, and the key considerations can be summarized in three points: 1) Patient factors (such as overall health, obesity, environment, and activity level) are the most critical considerations. 2) The amount of remaining ACL tissue   3) Presence of concomitant injuries   Among them, this article focuses on the second point—the significance of the remaining ACL tissue in treatment selection.

Introduction Total knee arthroplasty (TKA) is a relatively simple and straightforward procedure among knee surgeries.  However, some surgeons misunderstand fundamental surgical principles , leading to early prosthesis failure. If the surgery fails, revision TKA is technically demanding, and its outcomes are generally inferior to well-performed primary TKA. Therefore, precise surgical techniques must be employed during primary TKA to prevent early failure. In this article, we present a case in which improper ligament balancing, a fundamental principle, was overlooked, ultimately leading to early prosthesis failure.  

  S-Oil Championship (2023), held at Elysian CC in Jeju. Attended as a tour physician. Serious acute injuries are rare in golf tournaments. However, golfers often visit the medical room for conditioning, managing chronic pain, gastrointestinal discomfort, or upper respiratory symptoms. The Korean Society of Sports Medicine regularly assigns sports physicians to the official KLPGA Tour. Jeju Island is a beautiful location for the event. Fortunately, no serious injuries occurred during the competition.

Introduction The term "stem cell treatment" is highly appealing, drawing attention from both the public and the media. However, does stem cell therapy guarantee magical results ? The answer is: not always . While stem cell procedures can yield positive outcomes in carefully selected cases , they may provide little to no benefit in inappropriate cases , making the high cost of treatment unjustifiable . it is not uncommon to see patients who have undergone stem cell procedures at other hospitals without significant improvement—or, in some cases, with worsening symptoms .  Hereby, I introduce a  typical case frequently encountered in outpatient clinics.
