The Knee
-
Osteoarthritis (OA) of the knee is a chronic, progressive condition which often requires surgical intervention. The evidence for the benefits of arthroscopic debridement or washout for knee OA is weak and arthroscopy is currently only indicated in the UK if there is a history of mechanical locking of the knee. ⋯ Knee arthroscopy in the 60-74 and 75 and over age groups appears to be decreasing but there is still a large and increasing number of arthroscopic meniscal resections being performed.

Avulsion fractures of the anterior tibial intercondylar eminence in childhood are rare and are severe injuries of the knee. Since the injury is equivalent in aetiology with ruptures of the anterior cruciate ligament, the treatment requires anatomic reduction and preservation of the stability of the joint. The aim of the study was to demonstrate our experiences with the arthroscopy-guided Herbert-screw fixation in the treatment of displaced tibial eminence fractures in children. ⋯ Our results indicate that the presented method can successfully be applied in the treatment of displaced tibial spine fractures; providing excellent stability and preserving the function of the injured knee in the short-term.

Anterior cruciate ligament (ACL) rupture is a common lesion. Current treatment emphasizes arthroscopic ACL reconstruction via a graft, although this approach is associated with potential drawbacks. A new method of dynamic intraligamentary stabilization (DIS) was subjected to biomechanical analysis to determine whether it provides the necessary knee stability for optimal ACL healing. ⋯ Dynamic intraligamentary stabilization established and maintained close contact between the two ends of the ruptured ACL, thus ensuring optimal conditions for potential healing after primary reconstruction. The present ex vivo findings show that the DIS technique is able to restore AP stability of the knee.

Up to 30% of patients undergoing total knee arthroplasty (TKA) have received intra-articular corticosteroid injections prior to surgery. Debate exists as to whether such injections increase the rate of post-operative infection. Given that deep infection is a disastrous complication, a systematic review of the literature was undertaken to evaluate the safety of intra-articular corticosteroid injections given prior to TKA. Other features of corticosteroid use are also discussed including mechanism of action and optimal dosage. ⋯ III.
