Professor Sang Jun Song's research lab specializes in knee arthroplasty and osteotomies, with a focus on improving surgical outcomes through advanced implant design, navigation technology, and patient-specific considerations. The lab investigates long-term clinical results, prosthesis selection (such as cruciate-retaining vs. posterior-stabilized TKA), and the management of knee-related symptoms like joint noise. A key emphasis is placed on optimizing alignment, minimizing complications, and enhancing functional recovery in diverse patient populations, particularly Asian patients.

There has been continuing debate about the superiority of cruciate-retaining (CR) total knee arthroplasty (TKA) versus posterior-stabilized (PS) TKA for obtaining knee joint stability with functional improvement. Many surgeons tend to select the type of prosthesis on the basis of their own training and experience. However, the selection must be based on a great store of knowledge rather than on the surgeon's preconceptions or preferences. CR TKA may not be feasible in certain settings: posterior
Clinical results of high tibial osteotomy (HTO) deteriorate over time despite the initial satisfactory results. Several knees may require a conversion to total knee arthroplasty (TKA) because of failure such as the progression of degenerative osteoarthritis and the loss of the correction angle. It is important to know the long-term survival rate and common reason of failure in HTO to inform patients of postoperative expectations before surgery and to prevent surgical errors during surgery. In ad
Computer-assisted navigation is used to improve the accuracy and precision of correction angles during high tibial osteotomy. Most studies have reported that this technique reduces the outliers of coronal alignment and unintended changes in the tibial posterior slope angle. However, more sophisticated studies are necessary to determine whether the technique will improve the clinical results and long-term survival rates. Knowledge of the navigation technology, surgical techniques and potential pi

Noise in the knee joint is a common symptom that often leads to outpatient clinic visits. However, there have been no previous review articles regarding noise around the knee despite its high prevalence. We will review the noise characteristics according to sound nature and onset as well as factors for differentiation between physiological and pathological noises. In addition, we will describe causes of the physiological and pathological noises and management of noise in the knee. An appropriate
TKA using the Attune prosthesis provided more favorable clinical results than TKA using PFC Sigma. However, the risk of injury in the residual patella was increased with use of the Attune prosthesis in Asian patients.
