Professor Joon Ho Wang's research lab specializes in orthopedic tissue engineering and regenerative medicine, with a focus on developing advanced 3D bioprinted constructs for musculoskeletal repair. The lab investigates bioactive hydrogels—particularly those based on atelocollagen and supramolecular hyaluronic acid—engineered for mechanical stability and cellular integration to regenerate complex tissues such as osteochondral defects in the knee. Their work also extends to surgical biomechanics, including the evaluation of posterior cruciate ligament and posterolateral corner injuries, aiming to improve clinical outcomes through precise anatomical reconstruction and biomechanical assessment.

The use of cell-rich hydrogels for three-dimensional (3D) cell culture has shown great potential for a variety of biomedical applications. However, the fabrication of appropriate constructs has been challenging. In this study, we describe a 3D printing process for the preparation of a multilayered 3D construct containing human mesenchymal stromal cells with a hydrogel comprised of atelocollagen and supramolecular hyaluronic acid (HA). This construct showed outstanding regenerative ability for th
To prevent the unintentional increase of the posterior tibial slope, special attention should be paid to locate the intact cortical hinge on the lateral, not the posterolateral, side of the tibia.

Purpose The purpose of our study was to evaluate the reliability of the dial test by assessing the correlation between the severity of posterolateral corner injuries and the amount of external rotation of the tibia. Methods Fourteen paired cadaveric legs were fixed into a custom‐made isotonic rotation machine with the knee flexed at 30°. For group I (7 right knees), the lateral collateral ligament, popliteofibular ligament, popliteus tendon, and posterior cruciate ligament (PCL) were cut seriall

The results of this study support the claim that risk of iatrogenic popliteal vessel injury could be reduced by limited posterior capsular release during arthroscopic transtibial posterior cruciate ligament reconstruction.
Despite degenerative change progression, clinical outcomes were improved. The successful healing rate was 69.7% after repair of MMRTs. Compared with the unhealed group, the stable healed group showed better clinical outcomes and less degenerative change progression.
Surgeons must be cautious about the tension of soft tissue, even when using the navigation system during HTO.
Overcorrection after OWHTO surgery correlated with inferior PROs; therefore, overcorrected alignment should be avoided for patient satisfaction. Knees with an undercorrected alignment showed clinical results similar to those with appropriate correction.
