Recognized anatomic variations that lead to patella instability include patella alta and trochlea dysplasia. Lateralization of the extensor mechanism relative to the trochlea is often considered to be a contributing factor; however, controversy remains as to the degree this contributes to instability and how this should be measured. As the tibial tuberosity-trochlear groove (TT-TG) is one of most common imaging measurements to assess lateralization of the extensor mechanism, it is important to understand its strengths and weaknesses. Care needs to be taken while interpreting the TT-TG value as it is affected by many factors. Medializing tibial tubercle osteotomy is sometimes used to correct the TT-TG, but may not truly address the underlying anatomical problem. This review set out to determine whether the TT-TG distance sufficiently summarizes the pathoanatomy, and if this assists with planning of surgery in patellar instability. Cite this article:
Aims. The importance of accurate identification and reporting of surgical
site infection (SSI) is well recognised but poorly defined. Public
Health England (PHE) mandated collection of orthopaedic SSI data
in 2004. Data submission is required in one of four categories (hip
prosthesis, knee prosthesis, repair of neck of femur, reduction
of long bone fracture) for one quarter per year. Trusts are encouraged
to carry out post-discharge surveillance but this is not mandatory.
Recent papers in the orthopaedic literature have highlighted the
importance of SSI surveillance and the heterogeneity of surveillance
methods. However, details of current orthopaedic SSI surveillance
practice has not been described or quantified. Patients and Methods. All 147 NHS trusts in England were audited using a structured
questionnaire. Data was collected in the following categories: data
collection; data submission to PHE; definitions used; resource
Total knee arthroplasty (TKA) is a major orthopaedic
intervention. The length of a patient's stay has been progressively
reduced with the introduction of enhanced recovery protocols: day-case
surgery has become the ultimate challenge. This narrative review shows the potential limitations of day-case
TKA. These
Periprosthetic joint infection (PJI) is one of
the most feared and challenging complications following total knee arthroplasty.
We provide a detailed description of our current understanding regarding
the management of PJI of the knee, including diagnostic aids,
pre-operative planning, surgical treatment, and outcome. Cite this article:
