The primary indications for performing a medial closing wedge distal femoral osteotomy are valgus knee malalignment, lateral compartment overload, meniscus insufficiency, and/or osteoarthritis or cartilage damage. Without correction of this there is an increased risk chondral damage in the and patellofemoral knee. optimal candidates procedure young, active individuals with moderate to severe ar...

Objectives: As a surgical treatment option for cartilage defects in the knee, osteochondral allograft (OCA) transplantation reconstructs damaged area with fully formed articular hyaline cartilage/osseous unit. For patients undergoing this procedure, topography matching between donor and recipient sites is essential to limit premature wear of OCA. To help prevent graft failure, surgeon must prec...

This meta-analysis reviewed 12 studies comparing patient-specific instrumentation (PSI) with standard instrumentation (SI) for total knee arthroplasty in terms of postoperative coronal alignment and operation time. There is no significant difference between PSI and SI in terms of hip-knee-ankle angle (overall coronal alignment or mechanical axis), tibial coronal alignment, and operation time.

Total knee arthroplasty (TKA) is currently one of the most common orthopedic surgeries due to ever-increasing average life expectancy. The constant need for effective and accurate techniques was contributed development three-dimensional (3D) printing in that field, especially patient-specific instrumentation (PSI) custom-made implants fabrication. PSI may offer numerous benefits, such as resect...
