Q

How do menisci tears commonly present ?

A

Meniscal tears typically present with pain and swelling of the knee, and patients may complain of ‘locking’ or ‘buckling’ of the knee. Meniscal tears are best seen on MRI, and can be treated conservatively or surgically.

Q

How does transient synovitis present ?

A
  • Raised white cell counts and raised inflammatory markers may point to a more septic picture but may be normal in other conditions.
  • USS may show effusion and x-ray normal
  • If there is a high index of suspicion for septic arthritis - joint aspiration
  • Microscopy, culture and sensitivity of the joint aspirate will distinguish between the two, as bacteria within the joint space confirms septic arthritis.

Q

Describe the stepwise management of OA

A

First part of management is patient education and management of risk factors like weight loss, physiotherapy and OT. Orthotics ref-feral to support activities and function.

Stepwise use ofanalgesiato control symptoms:

  1. Oralparacetamoland topicalNSAIDsor topicalcapsaicin(chilli pepper extract).
  2. Add oralNSAIDsand consider also prescribing aproton pump inhibitor(PPI) to protect their stomach such asomeprazole. They are better used intermittently rather than continuously.
  3. Consideropiatessuch ascodeineandmorphine. These should be used cautiously as they can have significant side effects and patients can develop dependence and withdrawal. They also don’t work for chronic pain and result in patients becoming depending without benefitting from pain relief.

Intra-articular steroid injectionsprovide a temporary reduction in inflammation and improve symptoms.

Joint replacementcan be used in severe cases. The hip and knee are the most commonly replaced joints.
