[Hinews] As warmer weather encourages outdoor activities like hiking, walking, and golf, the incidence of osteoarthritis—a degenerative joint disease characterized by progressive articular cartilage loss, leading to pain, inflammation, and reduced range of motion—increases. This condition predominantly affects middle-aged and older adults, and without timely intervention, it can severely impair mobility and quality of life.

For early to mid-stage osteoarthritis with mild symptoms, treatments such as stromal vascular fraction (SVF) injections, derived from autologous adipose tissue, or platelet-rich plasma (PRP) injections can provide symptom relief. However, when cartilage damage is extensive, total knee arthroplasty (knee replacement surgery) often becomes necessary.

To enhance precision and overcome limitations of traditional surgery, 3D customized simulation knee replacement surgery is gaining prominence. This technique uses magnetic resonance imaging (MRI) to generate detailed images of the patient’s knee, enabling a three-dimensional simulation to tailor the surgical plan to the individual’s unique anatomy. The approach reduces operative time, minimizes incision size, and accelerates recovery. Notably, the PNK knee prosthesis, designed to align with the anatomical and kinematic characteristics of Korean patients, promotes natural knee motion and enhanced joint stability post-surgery.

“The 3D simulation technology improves surgical accuracy and enables patient-specific treatment, resulting in higher satisfaction rates,” said Dr. Yong-gon Go, director of YonseiSarang Hospital. “It is particularly beneficial for elderly patients or those with severe joint deformities.” He added, “The PNK prosthesis is engineered to closely replicate the mechanics of a healthy knee, facilitating a smoother return to daily activities. Success hinges on accurate diagnosis, meticulous 3D planning, and selecting the appropriate prosthesis for each patient.” Dr. Go also underscored the need for early intervention: “Osteoarthritis becomes increasingly difficult to treat as it progresses, so prompt evaluation is critical for those with persistent knee pain.”
