We compared the risks of re-revision and mortality between two-stage and single-stage revision surgeries among patients with infected primary hip arthroplasty. Patients with a periprosthetic joint infection (PJI) of their primary arthroplasty revised with single-stage or two-stage procedure in England and Wales between 2003 and 2014 were identified from the National Joint Registry. We used Poisson regression with restricted cubic splines to compute hazard ratios (HRs) at different postoperative periods. The total number of revisions and re-revisions undergone by patients was compared between the two strategies.Aims
Methods
Dead-space management, following dead bone resection, is an important element of successful chronic osteomyelitis treatment. This study compared two different biodegradable antibiotic carriers used for dead-space management, and reviewed clinical and radiological outcomes. All cases underwent single-stage surgery and had a minimum one-year follow-up. A total of 179 patients received preformed calcium sulphate pellets containing 4% tobramycin (Group OT), and 180 patients had an injectable calcium sulphate/nanocrystalline hydroxyapatite ceramic containing gentamicin (Group CG). Outcome measures were infection recurrence, wound leakage, and subsequent fracture involving the treated segment. Bone-void filling was assessed radiologically at a minimum of six months post-surgery.Aims

We compared the risks of re-revision and mortality between two-stage revision surgery and single-stage revision surgery among patients with infected primary knee arthroplasty. Patients with a periprosthetic joint infection (PJI) of their primary knee arthroplasty, initially revised with a single-stage or a two-stage procedure in England and Wales between 2003 and 2014, were identified from the National Joint Registry. We used Poisson regression with restricted cubic splines to compute hazard ratios (HR) at different postoperative periods. The total number of revisions and re-revisions undergone by patients was compared between the two strategies.Aims
Methods
Calcium sulphate has traditionally been used as a filler of dead space arising during surgery. Various complications have been described following the use of Stimulan bio-absorbable calcium sulphate beads. This study is a prospective observational study to assess the safety profile of these beads when used in revision arthroplasty, comparing the complication rates with those reported in the literature. A total of 755 patients who underwent 456 revision total knee arthroplasties (TKA) and 299 revision total hip arthroplasties (THA), with a mean follow-up of 35 months (0 to 78) were included in the study.Aims

The treatment of osteochondral lesions and osteoarthritis
remains an ongoing clinical challenge in orthopaedics. This review
examines the current research in the fields of cartilage regeneration,
osteochondral defect treatment, and biological joint resurfacing, and
reports on the results of clinical and pre-clinical studies. We
also report on novel treatment strategies and discuss their potential
promise or pitfalls. Current focus involves the use of a scaffold
providing mechanical support with the addition of chondrocytes or mesenchymal
stem cells (MSCs), or the use of cell homing to differentiate the
organism’s own endogenous cell sources into cartilage. This method
is usually performed with scaffolds that have been coated with a
chemotactic agent or with structures that support the sustained
release of growth factors or other chondroinductive agents. We also
discuss unique methods and designs for cell homing and scaffold
production, and improvements in biological joint resurfacing. There
have been a number of exciting new studies and techniques developed
that aim to repair or restore osteochondral lesions and to treat
larger defects or the entire articular surface. The concept of a
biological total joint replacement appears to have much potential. Cite this article:
