Kwak JM, et al. - Individuals treated with osteocapsular arthroplasty for posttraumatic stiffness were allocated to open procedure (OPEN) and arthroscopic procedure (ARTHRO) groups to validate the hypothesis that arthroscopic osteocapsular arthroplasty has a similar outcome to that of the corresponding open procedure. In both groups, the overall, range of motion, visual analog scale (VAS), and Mayo Elbow Performance Score (MEPS) scores exhibited improvement. In group intra-articular fracture vs group extra-articular fracture, all values for the clinical outcomes were worse. In conclusion, arthroscopic osteocapsular arthroplasty is similar to the corresponding open procedure relative to the use of these implications. Moreover, the clinical outcomes in the intra-articular fracture group as a former trauma were worse in comparison with those in the extra-articular fracture group.
