“…It must be noted, however, that a slight majority reported good or excellent OKS, but the total median score was 29, which can be categorized as fair [ 18 ]. Our OKS results are in accordance with previous studies [ 26 , 33 ]. Böhler et al reported an OKS of 29 (mean, n = 26) for revision arthroplasty in five-year mid-term follow-up for different single rotating hinge knee implants [ 33 ].…”

Background The purpose of this study was to determine the mid-term clinical, radiographic and health-related quality of life (HRQoL) outcomes and define the survival rate in patients who had undergone revision total knee arthroplasty (TKA) using the single rotating hinged knee (RHK) design. Methods Between January 2004 and December 2013, 125 revision TKAs were performed at our institution using the single RHK implant. We conducted both a retrospective analysis of prospectively collected outcome data of these patients and a prospective follow-up study of all 39 living patients (41 knees). The follow-up phase included an optional extra follow-up visit, PROM questionnaires, and plain radiographs. Results The ten-year Kaplan-Meier survival rate of the revision RHK knees was 81.7% (95% CI 71.9–91.6%) with re-revision for any reason as the endpoint. Overall, 15 knees (12% of the total) underwent re-revision surgery during the follow-up. The median follow-up was 6.2 years (range, 0–12.7 years) post-operatively for the baseline group. One mechanical hinge mechanism-related failure occurred without any history of trauma or infection. At the time of the final follow-up, the majority of patients evinced a fairly good clinical outcome measured with patient-reported outcome measures and none of the components were radiographically loose. Conclusion We found that in patients undergoing complex revision TKA, fairly good functional outcome and quality of life can be achieved using an RHK implant. Further, it seems that in this type of patient cohort, revision TKA using an RHK implant relieves pain more than it improves ability to function. The NexGen® RHK design can be regarded as a suitable option in complex revision TKA.

“…Moreover, the median 6.2 years follow-up can be considered satisfactory. To our knowledge, this study, which evaluated the efficacy of a single implant on revision TKA, has the largest cohort and longest follow-up for the NexGen® RHK implant in the published literature [ 11 , 21 – 33 ].…”

“…In 2017, Böhler et al analysed 50 patients (24 primary arthroplasties and 26 revisions), with a minimum follow-up of five years. 45 Clinical and radiographic examinations were performed pre-operatively as well as post-operatively after three and 12 months and yearly thereafter. The KSS, WOMAC, OKS and ROM were used for clinical assessment.…”

Possible indications for a rotating hinge or pure hinge implant in primary total knee arthroplasty (TKA) include collateral ligament insufficiency, severe varus or valgus deformity (> 20°) with relevant soft-tissue release, relevant bone loss, including insertions of collateral ligaments, gross flexion-extension gap imbalance, ankylosis and hyperlaxity. The use of hinged implants in primary TKA should be limited to the aforementioned selected indications, especially for elderly patients. Potential indications for a rotating hinge or pure hinge implant in revision TKA include infection, aseptic loosening, instability and bone loss. Rotating hinge knee implants have a 10-year survivorship in the range of 51% to 92.5%. Complication rates of rotating hinge knee implants are in the range of 9.2% to 63%, with infection and aseptic loosening as the most common complications. Although the results reported in the literature are inconsistent, clinical results generally depend on the implant design, appropriate technical use and adequate indications. Considering that the revision of implants with long cemented stems can be challenging, in the future it would be better to use shorter stems in modular versions of hinged knee implants.Cite this article: EFORT Open Rev 2019;4:121-132.

“…The latter is also available with PEEK articulation as an alternative to MOM. PEEK is a strong, wear-resistant polymer, but the clinical experience in arthroplasties is limited (Bohler et al., 2017). We have performed less than 2 years follow-up of 12 patients using PEEK, and are uncertain whether PEEK is better than MOM or UHMWP-metal.…”

We developed an uncemented screw-shaped ball-and-socket wrist prosthesis and modified it during a decade of trails from 1996 to 2005. The final Motec® wrist prosthesis was launched in 2006. Since then we have used this prosthesis in 110 wrists (110 patients) from 2006 to 2018. This article reviews the design, functional outcomes, complications, clinical usefulness and possible future modifications of the Motec® wrist prosthesis.
