Conversion Total Knee Arthroplasty After Tibial Plateau Fixation Is Associated With Lower Reimbursement, Greater Complication Rates, and Similar Opioid Use.

Cureus 2022 May 20;14(5):e25171. Epub 2022 May 20.

Orthopedics, University of Texas Southwestern Medical Center, Dallas, USA.

Objective Total knee replacement after previous open reduction and internal fixation for tibial plateau fracture (conversion total knee) increases the complexity of the procedure and the complication rate. However, very little research exists to report on opioid use and cost associated with total knee arthroplasty (TKA) following tibial plateau fracture fixation as compared to primary TKA patients with no history of tibial plateau fracture. The aim of this study is to compare the differences in opioid use, reimbursements, and complication rates between patients with and without a history of tibial plateau fracture undergoing TKA.

Strategies Trauma Limb Reconstr 2022 Jan-Apr;17(1):38-43

Department of Orthopedic Surgery, Hospital for Special Surgery, New York, United States of America.

Background: Common peroneal nerve (PN) palsy after total knee arthroplasty (TKA) is a serious complication. Although many authors suggest delayed or immediate PN decompression after TKA in these patients, little is known about the role of prophylactic peroneal nerve decompression (PPND) at the time of TKA. The aim is to report the results of PPND in high-risk patients at the time of TKA. Read More

Higher risk of knee arthroplasty during ten-year follow-up if baseline radiographic osteoarthritis involves the patellofemoral joint: a CHECK Cohort Study.

BMC Musculoskelet Disord 2022 Jun 22;23(1):600. Epub 2022 Jun 22.

Department of General Practice, Erasmus University Medical Center Rotterdam, Doctor Molewaterplein 40, 3015 GD, Rotterdam, Netherlands.

Background: Patellofemoral OA is a strong risk factor for progression to generalized whole knee OA, but it is unknown whether involvement of the patellofemoral joint in early radiographic OA (ROA) is associated with risk of undergoing future knee arthroplasty. This is clinically relevant because patellofemoral OA likely requires a different treatment approach than tibiofemoral OA, and identifying prognostic factors for future arthroplasty might assist clinicians with prioritizing and guiding early interventions that could improve long-term outcomes. Therefore, we evaluated association of baseline patellofemoral or tibiofemoral ROA with undergoing knee arthroplasty over 10 years. Read More

Pharmacological thromboprophylaxis as a risk factor for early periprosthetic joint infection following primary total joint arthroplasty.

Sci Rep 2022 Jun 22;12(1):10579. Epub 2022 Jun 22.

Department of Orthopaedics and Traumatology, Taipei Veterans General Hospital, No. 201, Sec 2, Shi-Pai Road, Taipei, 112, Taiwan.

Venous thromboembolism (VTE) prophylaxis has been suggested for patients who underwent total join arthroplasty (TJA). However, the morbidity of surgical site complications (SSC) and periprosthetic joint infection (PJI) has not been well evaluated. We aimed to evaluate the impact of VTE prophylaxis on the risk of early postoperative SSC and PJI in a Taiwanese population. Read More

Impact of keel saw blade design and thickness on the incidence of tibial plateau fracture and tibial implant-loosening in cementless medial UKR.

BMC Musculoskelet Disord 2022 Jun 21;23(1):597. Epub 2022 Jun 21.

Klinikum Garmisch-Partenkirchen, Endogap, Joint Replacement Institute, Auenstraße 6, 82467, Garmisch-Partenkirchen, Germany.

Background: Tibial plateau fractures and tibial implant- loosening are severe complications in cementless unicompartmental knee replacement (UKR). The tibial keel preparation is particularly demanding and different saw blades can be used. It was hypothesized that different blade designs and thickness have an influence on the frequency of tibial plateau fractures and implant-loosening in cementless medial UKR. Read More

Increasing trend of radiographic features of knee osteoarthritis in rheumatoid arthritis patients before total knee arthroplasty.

Sci Rep 2022 Jun 21;12(1):10452. Epub 2022 Jun 21.

Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8655, Japan.

To investigate the trend and factors related to the occurrence of osteoarthritis (OA)-like features on knee radiographs of rheumatoid arthritis (RA) patients undergoing total knee arthroplasty (TKA) in the recent decades. To classify antero-posterior knee radiographs into 'RA' and 'OA-like RA' groups, a deep learning model was developed by training the network using knee radiographs of end-stage arthropathy in RA patients obtained during 2002-2005 and in primary OA patients obtained during 2007-2009. We used this model to categorize 796 knee radiographs, which were recorded in RA patients before TKA during 2006-2020, into 'OA-like RA' and 'RA' groups. Read More

Revision Risk for Total Knee Arthroplasty Polyethylene Designs in Patients 65 Years of Age or Older: An Analysis from the American Joint Replacement Registry.

J Bone Joint Surg Am 2022 Jun 20. Epub 2022 Jun 20.

Department of Orthopaedics and Rehabilitation, Oregon Health & Science University, Portland, Oregon.

Background: Polyethylene bearing design may influence the risk of revision after total knee arthroplasty (TKA). Previous investigations from outside of the United States have suggested the potential for an increased risk of all-cause revision and revision for infection with the use of posterior-stabilized bearings. We examine the risk of revision based on the polyethylene bearing design selection for primary TKA. Read More

Orthop Clin North Am 2022 Jul 27;53(3):277-286. Epub 2022 May 27.

Orthopaedic Institute at Northwell Health, 210 East 64th Street, 4th Floor, New York, NY 10065, USA.

Extensor mechanism disruptions following total knee arthroplasty are devastating injuries with complication rates following surgical intervention ranging from 25% to 45%. Primary repair with and without augmentation is appropriate in certain limited clinical settings. Allograft reconstruction has been a popular option; however, synthetic grafts are showing promise and good results. Read More

Soft Tissue Procedures in the Multiply Operated on Knee Replacement Patient.

Orthop Clin North Am 2022 Jul;53(3):267-276

Department of Orthopaedics, University of British Columbia, Vancouver, British Columbia, Canada.

In the multiply operated on knee replacement, no one soft tissue procedure is vastly superior to another. The most extensive literature available is in relation to muscle flaps, which will continue to be the workhorse technique for orthopedic and plastic reconstructive surgeons for the foreseeable future. Closed incision negative pressure wound therapy may prove to be a superior method in time but further large-scale studies are required to expand our understanding of this technique. Read More

Am J Phys Med Rehabil 2022 Jul 4;101(7):666-673. Epub 2021 Oct 4.

From the Department of Physiotherapy, Singapore General Hospital, Singapore (Y-HP, JW-MT, CL-LP, ES-XC, E-LW); Medicine Academic Programme, Duke-NUS Graduate Medical School, Singapore (Y-HP, JT); Department of Physiotherapy, Seng Kang General Hospital, Singapore (FJ-TS); Department of Rheumatology and Immunology, Singapore General Hospital, Singapore (JT); Health Services Research and Evaluation, Singhealth Office of Regional Health, Singapore (JT); Department of Orthopaedic Surgery, Singapore General Hospital, Singapore (S-JY); and Research Health Institute, University of the Sunshine Coast, Sunshine Coast, Australia (RAC).

Objective: After total knee arthroplasty, the ability to weight bear symmetrically during the sit-to-stand task provides important information regarding altered movement patterns. Despite this, comprehensive recovery curves and validity data for sit-to-stand weight-bearing symmetry are lacking in the total knee arthroplasty population. Our study aimed to (1) develop recovery curves with reference ranges, (2) identify the correlates of standard and constrained sit-to-stand weight-bearing symmetry, and (3) evaluate their predictive validity with gait speed.
