Understanding loss of internal rotation after reverse shoulder arthroplasty: a narrative review of current literature.

Background: Functional internal rotation (fIR) can be limited after reverse shoulder arthroplasty (RSA) and can result in difficulties performing activities of daily living (ADLs). The goal of this narrative review is to summarize the growing body of research on optimizing fIR after RSA that may be useful to clinical practice.

Methods: A narrative review of recent literature on IR after RSA.

A Systematic Review of the Efficacy and Safety of Ketamine in Total Joint Arthroplasty.

Background: Ketamine is administered intraoperatively to treat pain associated with primary total hip (THA) and knee arthroplasty (TKA). The purpose of this study was to evaluate the efficacy and safety of ketamine in primary THA and TKA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons (AAHKS), American Academy of Orthopaedic Surgeons (AAOS), Hip Society, Knee Society, and the American Society of Regional Anesthesia and Pain Management (ASRA).

Methods: The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for studies published prior to 2020 on ketamine in THA and TKA.

The Efficacy and Safety of Periarticular Injection in Total Joint Arthroplasty: A Direct Meta-Analysis.

Background: Periarticular injection (PAI) is administered intraoperatively to help reduce postoperative pain and opioid consumption after primary total joint arthroplasty (TJA). The purpose of this study was to evaluate the efficacy and safety of PAI in primary TJA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Medicine.

Methods: The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for studies published prior to March 2020 on PAI in TJA.

The Efficacy and Safety of Corticosteroids in Total Joint Arthroplasty: A Direct Meta-Analysis.

Background: Corticosteroids are commonly used intraoperatively to treat pain and reduce opioid consumption and nausea associated with primary total joint arthroplasty (TJA). The purpose of this study was to evaluate the efficacy and safety of corticosteroids in primary TJA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and the American Society of Regional Anesthesia and Pain Management.

Methods: The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for studies published before February 2020 on corticosteroids in TJA.

Long-Term Results of Delta Ceramic-on-Ceramic Total Hip Arthroplasty.

Background: Ceramic-on-ceramic (COC) bearings in total hip arthroplasty (THA) have long been considered the coupling with the lowest overall wear. However, concerns about complications such as ceramic breakage and noise, combined with the improved performance of polyethylene, have limited its use in the United States. This postapproval follow-up reports long-term (10 years) results of Delta COC in THA patients primarily enrolled in an Investigational Device Exemption study.

The Efficacy and Safety of Nonsteroidal Anti-Inflammatory Drugs in Total Joint Arthroplasty: Systematic Review and Direct Meta-Analysis.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) have become widely used to manage perioperative pain following total joint arthroplasty (TJA). The purpose of our study is to evaluate the efficacy and safety of NSAIDs in support of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Management.

Methods: Databases including MEDLINE, EMBASE, and the Cochrane Central Registry of Controlled Trials were searched for studies published prior to November 2018 on NSAIDs in TJA.

Bone Attachment on a New Design of Cementless Stem and a Widely Used Cup: Postmortem Retrieval Findings.

Case: This was a postmortem retrieval study to assess bone fixation in a hydroxyapatite-coated ACTIS stem and a beaded Pinnacle Sector cup retrieved from an 89-year-old man 15-months postoperatively. Previous radiographic examinations showed good implant fixation without any radiolucency. The sectioned cup and stem showed good fixation on visual, microradiographic, and histological examinations.

The Efficacy and Safety of Gabapentinoids in Total Joint Arthroplasty: Systematic Review and Direct Meta-Analysis.

Background: Gabapentinoids are commonly used as an adjunct to traditional pain management strategies after total joint arthroplasty (TJA). The purpose of this study is to evaluate the efficacy and safety of gabapentinoids in primary TJA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and the American Society of Regional Anesthesia and Pain Management.

Methods: The MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were searched for studies published prior to November 2018 on gabapentinoids in TJA.

The Efficacy and Safety of Opioids in Total Joint Arthroplasty: Systematic Review and Direct Meta-Analysis.

Background: Opioids are frequently used to treat pain after total joint arthroplasty (TJA). The purpose of this study was to evaluate the efficacy and safety of opioids in primary TJA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and the American Society of Regional Anesthesia and Pain Management.

Methods: The MEDLINE, EMBASE, and Cochrane Central Register of controlled trials were searched for studies published before November 2018 on opioids in TJA.

The Efficacy and Safety of Acetaminophen in Total Joint Arthroplasty: Systematic Review and Direct Meta-Analysis.

Background: Oral and intravenous (IV) acetaminophen has become widely used perioperatively as part of a multi-modal pain management protocol for primary total joint arthroplasty (TJA). The purpose of our study is to evaluate the efficacy and safety of acetaminophen in support of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Management.

Methods: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for studies published prior to September 2019 on acetaminophen in primary TJA.

Survivorship of polyethylene liner exchanges performed for the treatment of wear and osteolysis among porous-coated cups.

For the past 17 years, we have favored treating patients with polyethylene wear and osteolysis by performing a liner exchange with retention of the old shell when possible. Using our institutional database, we identified 187 acetabular revisions in which we had retained the old shell. Among this group, we found 25 rerevisions.

Five Duraloc locking ring failures.

We report on 5 cases that underwent revision for locking ring failure in the Duraloc product line (DePuy, Warsaw, Ind). All liner retrievals showed signs of posterior neck/liner impingement and superior edge loading or significant wear. In these cases, we believe superior head migration and neck/liner impingement due to cup anteversion contributed to these locking ring failures.

Learning curve with minimally invasive unicompartmental knee arthroplasty.

This study examined 445 consecutive minimally invasive unicompartmental knee arthroplasties (UKAs) from one institution to determine whether revision and reoperation rates would decrease as the number of cases performed increased, indicating the presence of a learning curve with this procedure. At a mean of 3.25 years, 26 knees required revision yielding an overall revision rate of 5.
