In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly cross-linked polyethylene acetabular liner. Radiography and CT scans were used to evaluate bone retention, component position, joint biomechanics, and osteolysis. Extensive research and laboratory tests have led to the design of the Custom Polyethylene Hip Resurfacing. Hip resurfacing with a highly cross-linked polyethylene acetabular liner and titanium nitride-coated femoral component. Two participants were lost to follow-up and 2 died. 2012 Feb;470(2):366-72. doi: 10.1007/s11999-011-1950-7. This is the first hip resurfacing device developed for canines, and this study is the first to characterize the in vitro wear of highly cross‐linked polyethylene liners in a hip resurfacing implant. Conclusions: Resurfacing with a highly cross-linked polyethylene acetabular component and a titanium nitride-coated titanium cementless femoral component is a reliable and bone-conserving procedure at mid-term.

Conclusions: Resurfacing with a highly cross-linked polyethylene acetabular component and a titanium nitride-coated titanium cementless femoral component is a reliable and bone-conserving procedure at mid-term. Keywords: Hip resurfacing; highly cross-linked polyethylene There are four practical considerations that are limiting for hip resurfacing: (I) hip resurfacing is a difficult technical procedure that invites errors. Prevention and treatment information (HHS). The mean follow-up was 8.5 (range, 7-10) years. Highly crosslinked polyethylene (XLPE) has demonstrated clinical success in total hip arthroplasty (THA) and, when used in HRA, potentially reduces metal ion-related sequelae. National Library of Medicine Background: In the 1970s and 1980s, hip resurfacing was largely unsuccessful, due to impingement, wear, and component loosening. Hip resurfacing using a highly cross-linked polyethylene acetabular component is a reliable procedure. Highly cross-linked polyethylene (XLPE) has improved wear properties. Seven polyethylene retrievals had a measured wear rate of 0.05 mm/y. Journal Arthroplasty 31, 2203–2208. Highly cross-linked polyethylene as a bearing surface for hip resurfacing produced satisfactory functional results, bone conservation, maintenance of biomechanics, and implant survivorship.

This is an anteroposterior radiograph of a 44-year-old woman Lin ZM, Meakins S, Morlock MM, Parsons P, Hardaker C, Flett M, Issac G. Deformation of press-fitted metallic re-surfacing cups. It is a conceptually attractive solution to hip arthritis for young and active patients. Aims: Highly cross-linked polyethylenes To reduce wear rates and particulate debris, highly cross-linked polyethylene (XLPE) has been used in total hip arthroplasty for 8 years. Our e-learning platform contains high resolution images and a certified CME of the Polymotion; The Custom Highly Crosslinked Polyethylene Hip Resurfacing … The 3D optical scanner had an average accuracy of 2.1 µm and an average precision of 1.4 µm, which corresponded to errors less than 10% when measuring wear depths of 20 µm or greater. To help ensure optimal wear resistance, Zimmer Biomet employs a proprietary process. The highly cross-linked polyethylene had a minimum thickness of 3.6 mm at the dome and 2.7 mm at the periphery. Acetabular bone conservation was assessed using computed tomography by measuring the medial acetabular wall. The low incidence of osteolysis and the low rate of wear found on retrievals suggest that many years of use in highly active patients is possible. Today, the availability of better technique and highly cross-linked polyethylene avoids the early causes of failure and provides a successful solution to younger, active patients with advanced osteoarthritis. These results suggest that the thin liners will not prematurely crack after implantation in canines. Retrieved polyethylene liners were analyzed for wear. Ann Joint 2020; 5:10. This technique was then used to measure the in vitro wear of a hip resurfacing device for canines that incorporates a highly cross-linked polyethylene liner. Highly cross-linked polyethylene; hip resurfacing; titanium femoral component. Advantages over total hip arthroplasty include a more normal gait and a lower incidence of thigh pain.

There was no polyethylene wear through or osteolysis. Discussion Periprosthetic inflammatory masses occurring after total hip arthroplasty (THA) have sometimes been described as “inflammatory pseudotumors” [1] . I performed 234 resurfacing procedures (192 patients) using a two-piece titanium acetabular component with a 4 mm highly cross-linked polyethylene liner and a cementless titanium nitride-coated titanium femoral component.

The mean medial acetabular thickness was 9 mm postoperatively versus 14 mm preoperatively ( p = 0.019). Its use in the tibial tray for total knee arthroplasty (TKA), however, has been much more controversial. The Kaplan-Meier survivorship was 97%. Clinical studies to date show a 50% to 87% reduction in wear.7,12,13 Cross-linked polyethylene has been produced and approved for use for femoral head diameters Figure 4A-B.

Keywords: Additional structural bone grafts and/or fixation were not used. J Arthroplasty. A cemented or cementless resurfacing prosthesis was used on the femur. However, a potential problem with reducing liner thickness with highly cross-linked polyethylene is that thin liners are potentially more susceptible The manufacturing process for these materials cross-links the molecules and im­proves wear characteristics but slightly reduces the strength of the polyethylene. 2015 Apr 15;97(8):627-34. doi: 10.2106/JBJS.N.00605.

Pritchett JW (2016) Hip resurfacing using highly cross-linked polyethylene: prospective study results at 8.5 years. Highly cross-linked polyethylene (HXLPE) has been and continues to be commonly used for liners in total hip arthroplasty (THA) due to its known ability to reduce wear during articulation.
