A protective hinge wire, intersecting the osteotomy plane, can reduce the occurrence of perioperative hinge fractures in medial opening wedge osteotomy
AbstractPurposeA recent study reported that positioning a K-wire to intersect the cutting plane at the theoretical lateral hinge location increases the lateral hinge ’s resistance to fracture during the opening of opening wedge high tibial osteotomy (OWHTO). The purpose of this study was to evaluate the clinical relevance of the use of this K-wire and its benefits in terms of lateral hinge protection during OWHTO in daily practice.MethodsA retrospective comparative study identified 206 patients who underwent OWHTO from January 2014 to December 2017. Among these patients, 71 had an additional K-wire (HK  +&thin...

Surgery for patellar dislocation has evolved towards anatomical reconstructions with assessment and treatment of anatomical risk factors
ConclusionThe incidence of surgical procedures for patellar dislocation remained unchanged during the years 1997 –2016. Ligament reconstruction procedures increased in popularity. Surgical techniques have shifted towards the reconstruction of damaged structures and the modification of congenital anatomical risk factors for patellar dislocation. Diversified surgical techniques have enabled the tailoring and c ombining of stabilizing procedures according to the patient’s individual anatomy.

Low polyethylene creep and wear following mobile-bearing unicompartmental knee replacement
ConclusionDuring the first three to six months after implantation, the bearing becomes 0.06  mm thinner due to creep. The combined wear rate of the upper and lower surfaces of the bearing is constant (0.07 mm/year). The wear is lower if the bearing does not overhang the tibia so surgeons should aim for the bearing to be close to the tibial wall. The orientation of the femoral component d oes not influence wear.Level of evidenceRetrospective Study, Level III. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)
