The analgesic efficacy and safety of peri-articular injection versus intra-articular injection in one-stage bilateral total knee arthroplasty: a randomized controlled trial.

Background: As an essential component of multimodal analgesia approaches after total knee arthroplasty (TKA), local infiltration analgesia (LIA) can be classified into peri-articular injection (PAI) and intra-articular injection (IAI) according to administration techniques. Currently, there is no definite answer to the optimal choice between the two techniques. Our study aims to investigate analgesic efficacy and safety of PAI versus IAI in patients receiving simultaneous bilateral TKA.

Literature was also identified by tracking using reference lists.

Diagnosis and Treatment of Arterial Occlusion after Knee Arthroplasty: The Sooner, the Better.

Knee arthroplasty, including total knee arthroplasty (TKA) and unicondylar knee arthroplasty (UKA), is an effective procedure for patients with severe knee joint diseases. Arterial occlusion after knee arthroplasty is a rare but severe complication. However, there are few comprehensive reviews or analyses focusing on it.

Role of Parecoxib Sodium in the Multimodal Analgesia after Total Knee Arthroplasty: A Randomized Double-blinded Controlled Trial.

Objective: Total knee arthroplasty (TKA) is an established surgical technique and is the standard treatment for degenerative knee joint diseases. However, severe pain after TKA makes it difficult for many patients to perform early postoperative rehabilitation and functional exercise, which might result in subsequent unsatisfactory recovery of knee joint function and great reduction in patients' satisfaction and quality of life. Orthopaedic surgeons have tried a large variety of analgesics and analgesic modes to relieve patients' pain after TKA.

Study on biocompatibility, tribological property and wear debris characterization of ultra-low-wear polyethylene as artificial joint materials.

Ultra-low-wear polyethylene (ULWPE) is a new type polyethylene made by experts who are from China petrochemical research institute, which is easy to process and implant. Preliminary test showed it was more resistant to wear than that of Ultra-high-molecular weight polyethylene (UHMWPE). The purpose of the research is to study biocompatibility, bio-tribological properties and debris characterization of ULWPE.

Total Hip Arthroplasty in Hemophilia Patients: A Mid-term to Long-term Follow-up.

Objective: To report the results of mid-term to long-term follow-up after primary total hip arthroplasty (THA) in hemophiliacs and to hypothesize that THA can provide satisfactory outcomes in these patients.

Methods: Twenty-four primary THA performed in 21 hemophilia patients between 2002 and 2012 were reviewed retrospectively, including 20 cases of hemophilia A and 1 case of hemophilia B. The standard lateral approach was used for all implantations.

Surgical Treatment for Hemophilic Pseudotumor: Twenty-three Cases with an Average Follow-up of 5 Years.

Background: Hemophilic pseudotumor (HPT) is a rare disease with many challenges. Only a few reports on surgical treatment for HPT have been published.

Methods: The cases of 23 patients with HPT who had surgical treatment from July 1996 to December 2014 were retrospectively reviewed.

[Comparison of Clinical Influence of Intramedullary versus Extramedullary Alignment Guides on Total Knee Arthroplasty].

Unlabelled: Objective: To compare the clinical influence of intramedullary versus extramedullary alignment guides on total knee arthroplasty (TKA) in terms of alignment of the lower limbs,intraoperative tourniquet time,and postoperative complications.

Ceramic on Ceramic or Ceramic-on-polyethylene for Total Hip Arthroplasty: A Systemic Review and Meta-analysis of Prospective Randomized Studies.

Background: Wear debris of polyethylene has become a restraining factor of the durability for total hip arthroplasty (THA). Ceramic on ceramic (COC) has better wear resistance while the squeaking sound and prosthesis fracture are of concern. It is still a controversy that bearing couples are better for THA.
