Outcomes of distal femoral arthroplasty after periprosthetic fractures : minimum 2-year follow-up.

Acta Orthop Belg 2021 Mar;87(1):111-116

Purpose: distal femoral periprosthetic fracture (DFPPF) is a serious complication following total knee arthroplasty (TKA). Recently, treatment of DFPPF with distal femoral arthroplasty (DFA) has gained popularity because of its posited benefits for both patients and the medical system. Short-term follow-up trials investigating DFA have demonstrated acceptable results with regards to function, pain relief and lower postoperative complications than ORIF in elderly patients.

Influence of outpatient total knee arthroplasty compared to inpatient surgery on medical and economic outcomes.

Acta Orthop Belg 2021 Mar;87(1):103-109

Firstly, this study compared the rate of readmission after a total knee arthroplasty between selected out- patients (no hospitalization, directly sent home after surgery) and inpatients (3 days hospitalization) at 6 weeks. Secondly, it examined the mobility and the complications in the two groups after the same period of time. The rate of readmission, complications and knee mobility of 32 outpatients (M-age : 61 years ± 10 ; 10 females), were compared against those of 32 birth- matched inpatients (M-age : 64 years ± 8.

Bicruciate retaining total knee arthroplasty : results throughout history.

Acta Orthop Belg 2021 Mar;87(1):73-83

Approximately 20% amongst patients are dissatisfied after total knee arthroplasty (TKA). Bicruciate retaining (BCR) TKA offers superior knee kinematics and proprioception, but many surgeons abandoned its use because of complications and technical difficulties. Recently, two new BCR implant designs were introduced : Vanguard XP (Zimmer Biomet) and Journey XR (Smith&Nephew). Read More

Same-day discharge arthroplasty has a higher overall complications rate than fast-track arthroplasty: a systematic review and meta-analysis.

Arch Orthop Trauma Surg 2021 Jun 15. Epub 2021 Jun 15.

Department of Orthopedics, Orthopedic Research Institute, West China Hospital, Sichuan University, 37# Guoxue Road, 610041, Chengdu, Sichuan, People's Republic of China.

Background: Published studies have reported many inconsistent results regarding the comparison of same-day discharge total joint arthroplasty (TJA) and inpatient TJA. More notably, many recent studies comparing same-day discharge TJA with fast-track TJA presented higher rates of complications for same-day discharge TJA, which raises concerns about the safety of same-day discharge TJA.

Methods: We systematically searched the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases up to June 2020 for studies comparing mortality, readmission, and complications in same-day discharge and inpatient total hip or knee arthroplasty. Read More

Perioperative Statin Use May Reduce Postoperative Arrhythmia Rates After Total Joint Arthroplasty.

J Arthroplasty 2021 May 25. Epub 2021 May 25.

Department of Orthopaedic Surgery, Stanford Hospital and Clinics, Redwood City, CA.

Background: Postoperative arrhythmias are associated with increased morbidity and mortality in total joint arthroplasty (TJA) patients. HMG-CoA (3-hydroxy-3-methyl-glutaryl-CoA) reductase inhibitors (statins) decrease atrial fibrillation rates after cardiac surgery, but it is unknown if this cardioprotective effect is maintained after joint reconstruction surgery. We aim to determine if perioperative statin use decreases the incidence of 90-day postoperative arrhythmias in patients undergoing primary TJA. Read More

Interposition arthroplasty: Current indications, technique and expectations.

J Clin Orthop Trauma 2021 Aug 19;19:175-182. Epub 2021 May 19.

Department of Orthopaedic Surgery, Mayo Clinic, Rochester, MN, 55905, USA.

The ultimate means of functional restoration of joints with end stage arthritis is prosthetic replacement. Even though there is reluctance to replace the joint of a younger individual, the mean age of joint replacement continues to decrease. This is due to three factors: 1) social expectations, 2) uncertainty with many joint preservation procedures and 3) the ever-increasing reliability and longevity of prosthetic replacement. Read More

The Double DAIR: A 2-Stage Debridement with Prosthesis-Retention Protocol for Acute Periprosthetic Joint Infections.

JBJS Essent Surg Tech 2021 Jan-Mar;11(1). Epub 2021 Feb 4.

Department of Orthopaedic Surgery, Mayo Clinic, Phoenix, Arizona.

Background: Debridement and implant retention (DAIR) has variable success as a treatment for acute periprosthetic joint infection (PJI), with generally poor outcomes reported in the literature. Because of the unacceptably high failure rate of DAIR, we implemented a 2-stage debridement protocol that includes the use of high-dose antibiotic beads between stages for the treatment of acute PJI. In 2 previous studies, with an average follow-up of 3. Read More

Application of 3D Printing in Hip and Knee Arthroplasty: A Narrative Review.

Indian J Orthop 2021 May 6;55(Suppl 1):14-26. Epub 2020 Oct 6.

Department of Orthopaedics, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Introduction: Ideal surgical positioning and placement of implants during arthroplasty are crucial for long-term survival and optimal functional outcomes.

Rest-activity daily rhythm and physical activity levels after hip and knee joint replacement: the role of actigraphy in orthopedic clinical practice.

Chronobiol Int 2021 Jun 14:1-10. Epub 2021 Jun 14.

IRCCS Istituto Ortopedico Galeazzi, Milano, Italy.

Elective hip and knee joint replacement for osteoarthritis are cost-effective surgical procedures requiring specific rehabilitation programs. Actigraphy is widely used in both research and clinical practice to study activity patterns with great accuracy and validity but it has never been utilized in orthopedic patients. Therefore, the aim of this study was to objectively assess, through actigraphy, physical activity (PA) levels and rest-activity daily rhythm (RAR) in patients undergoing hip or knee joint replacement and hospitalized for ten days after surgery.
