Posttraumatic arthritis

At the Mayo Clinic, Polycentric UKA was only performed on patients with unicondylar disease (osteoarthritis) [20, 21]. An initial assessment was based on radiographic screening. However, the UKA implantation technique involved the same exposure as in TKA, so that both compartments could be directly examined and evidence of unicompartmental disease visually confirmed. Mallory also reported the utility of polycentric UKA in the treatment of posttraumatic arthritis due to fracture-induced deformity of the knee [22]. 

Reverse prosthesis designs were developed for use in cases of rotator cuff tear arthropathy, and although they continue to be used primarily in such cases, they have also been used in others. From a series of 240 reverse prosthesis cases. Wall and colleagues [39] report that 31% were used for rotator cuff tear arthropathy, 22.5% for revision arthroplasty, 17% for massive rotator cuff tears, 14% for primary OA, and 14% for posttraumatic arthritis. In marked contrast to other TSA studies, only 1 of the 240 cases reported by Wall and coworkers was done for RA [39]. 

Taking a closer look at these results shows differences with respect to a number of variables. The indications for TSA are varied and therefore present unique challenges to the repair. In general, standard TSA performed to address problems caused by primary arthritis (OA or RA) are the most successful [18, 20, 22, 24, 26, 29, 74], and the success rates for standard TSA performed to address problems due to fracture are substantially lower [1, 5]. In younger patients (less than 50 years old), the results for TSA are also generally less successful than those performed in older patients [1, 6, 21]. Similarly, results for reverse TSA are better when it is used in cases of rotator cuff tear arthropathy than when it is used in cases of revision or posttraumatic arthritis [38, 39].
