Correlation between EFAS- and MOCART score and clinical outcome after AMIC-procedure for osteochondral lesion of the talus.

Arch Orthop Trauma Surg 2022 May 21. Epub 2022 May 21.

Centre for Foot and Ankle Surgery, Schön Klinik München Harlaching, Harlachinger Strasse 51, 81547, Munich, Germany.

Introduction: Even though an increased interest in the use of the EFAS Score (European Foot and Ankle Society) has been observed, no data comparing it with radiological findings has been presented in the literature. Accordingly, the aim of this study is to investigate how the post-operative integration of the AMIC (autologous matrix-induced chondrogenesis)-membrane for osteochondral lesion of the talus using the MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) - Score is related to the clinical satisfaction of the patients.

The effects of tourniquet on cement penetration in total knee arthroplasty.

Arch Orthop Trauma Surg 2022 May 13. Epub 2022 May 13.

Division of Adult Reconstruction, NYU Langone Orthopedic Hospital, Hospital for Joint Diseases, NYU Langone Health, 301 East 17th Street, New York, NY, 10003, USA.

Purpose: Aseptic loosening is a common cause of implant failure following total knee arthroplasty (TKA). Cement penetration depth is a known factor that determines an implant's "strength" and plays an important role in preventing aseptic loosening. Tourniquet use is thought to facilitate cement penetration, but its use has mixed reviews. Read More

Cure rate of infections is not an argument for spacer in two-stage revision arthroplasty of the hip.

Arch Orthop Trauma Surg 2022 May 9. Epub 2022 May 9.

Department of Orthopedic Surgery and Traumatology, Charité, University Hospital Berlin, Charitéplatz 1, 10117, Berlin, Germany.

Introduction:  A devastating complication after total hip arthroplasty (THA) is chronic periprosthetic joint infection (PJI). Most frequently spacers (Sp) with or without antibiotics are implanted in a two-stage procedure even though not always indicated due to unknown pathogen, femoral and acetabular defects or muscular insufficiency.

Materials And Methods:  A retrospective analysis of a prospectively collected database was conducted, analyzing the treatment of 44 consecutive cases with chronic PJI undergoing two-stage revision using a Girdlestone situation (GS) in the interim period between 01/2015 and 12/2018. Read More

Arch Orthop Trauma Surg 2022 May 9. Epub 2022 May 9.

Center for Anatomy and Cell Biology, Medical University of Vienna, Vienna, Austria.

Introduction: This study investigated the anatomic feasibility of a new surgical therapy option for radial head arthrosis using an autologous vascularized bone graft of the second metatarsal and proximal fibula to recreate the proximal radiohumeral joint.

Materials And Methods: Upper and lower extremities of eleven body donors were evaluated using CT prior to anatomic dissection. Several distinct anatomic parameters were measured on the ipsi- and contralateral radial and fibular head and the second metatarsal base: bone diameter, articular surface diameter, head height, metaphyseal (neck) diameter, articular surface radius, total articular surface area, and angulation of the articular surfaces (facet).

Is there any clinical advantage of capsular repair over capsular resection for total hip arthroplasty? An updated systematic review and meta-analysis.

Arch Orthop Trauma Surg 2022 May 6. Epub 2022 May 6.

Department of Orthopaedic Surgery, Yokohama City University, Yokohama, Japan.

Introduction: Although several surgical approaches, with or without capsular repair, can be used during total hip arthroplasty (THA), there is no clear evidence that capsular repair provides a clinical advantage post-surgery, regardless of surgical approach. This systematic review and meta-analysis evaluated whether capsular repair using various surgical approaches provides a clinical advantage over capsular resection post-THA.

Methods: This study was conducted in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 checklist for systematic reviews and meta-analyses. Read More

Posterior stabilization with polyetheretherketone (PEEK) rods and transforaminal lumbar interbody fusion (TLIF) with titanium rods for single-level lumbar spine degenerative disease in patients above 70 years of age.

Arch Orthop Trauma Surg 2022 May 5. Epub 2022 May 5.

Department of Spine Surgery, University Hospital of Basel, Spitalstrasse 21, 4051, Basel, Switzerland.

Background: Given the lack of guidelines regarding the operative management of elderly patients needing lumbar spine fusion for degenerative disease, it is often difficult to balance between invasiveness respecting the fragile spine and geriatric comorbidities.

Aim: To compare reoperation rates and clinical outcome in patients above 70 years of age undergoing Transforaminal Lumbar Interbody Fusion (TLIF) with titanium rods or posterior stabilization with Polyetheretherketone (PEEK) rods for the treatment of one-level lumbar spine degenerative disease.

Methods: Retrospective review of baseline characteristics, reoperation rates as well as the clinical and radiological outcomes of patients, older than 70 years, undergoing posterolateral fusion with PEEK rods (n = 76, PEEK group) or TLIF with titanium rods (n = 67, TLIF group) for a single-level lumbar degenerative disease from 2014 to 2020.

Is a preoperative pathogen detection a prerequisite before undergoing one-stage exchange for prosthetic joint infection of the hip?

Arch Orthop Trauma Surg 2022 May 4. Epub 2022 May 4.

Center for Musculoskeletal Surgery, Department of Orthopaedic Surgery, Charité - Universitätsmedizin Berlin, Charitéplatz 1, 10117, Berlin, Germany.

Background: A preoperative pathogen detection is considered a prerequisite before undergoing one-stage exchange for prosthetic joint infection (PJI) according to most guidelines. This study compares patients with and without preoperative pathogen detection undergoing one-stage exchange for PJI of the hip.

Noise exposure during robot-assisted total knee arthroplasty.

Arch Orthop Trauma Surg 2022 May 4. Epub 2022 May 4.

Department of Orthopedic Surgery, Hannover Medical School, Anna-von-Borries-Str. 1-7, 30625, Hannover, Germany.

The aim of the study was to examine the noise exposure for operating theater staff during total knee arthroplasty (TKA) with three different robot systems. There is already evidence that noise exposure during TKA performed manually exceeds recommended guidelines for occupational noise. Therefore, if surgical staff is exposed to it for several years, the development of noise-inducing hearing loss (NIHL) is significantly increased. Read More

Preemptive multimodal analgesia and post-operative pain outcomes in total hip and total knee arthroplasty.

Arch Orthop Trauma Surg 2022 May 2. Epub 2022 May 2.

Department of Pharmacy, OhioHealth Doctors Hospital, 5100 West Broad Street, Columbus, OH, 43228, USA.

Background: Use of multimodal analgesia (MMA) prior to orthopedic surgery has been adopted by many practitioners as a strategy to minimize use of opioid medications. The purpose of this investigation was to quantify the effect of a preemptive three-drug regimen (acetaminophen, celecoxib, and gabapentin) in terms of post-operative opioid consumption and pain control in the field of total joint arthroplasty.

Methods: A retrospective chart review was conducted on 1691 patients who underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA) and stratified by whether they received a preemptive three medication analgesic therapy (acetaminophen, celecoxib, and gabapentin) within 30 to 60 min prior to entering the operating room.
