Knee Fusion (Subscribe)  

Aggressive juxta-articular giant cell tumours of the lower limbs occurring in young patients are a challenge to the average orthopaedic surgeon. Although it is the treatment of choice for these tumours, wide resection creates a problem for the reconstruction of large bone gaps. We describe our results after resection arthrodesis...

Twenty knees, in which a total of 32 previous operations had been performed, were arthrodesed by the Charnley compression technique combined with intramedullary nailing. Patients with previous infection were excluded from the series, but three neuropathic knees were included. Bony union was evident after an average of six months in...

Principles
Accurate fitting of concellous surfaces in correct position is of extreme importance
Use TKR cutting blocks
Charnley (1948) used compression clamps with pins placed 4cm from cut surfaces
Use of two pins at either end better control of angular movement about osteotomy.
Charnley used near full extension in children as grow into flexion
Indications: Historically TB...

Nine patients underwent arthrodesis of the knee using customised coupled nail (the Mayday arthrodesis nail), five after infected arthroplasty, one following failed arthrodesis, one for intractable anterior knee pain, one for Charcot instability and one after trauma. Comparison was made with 17 arthrodeses, eight undertaken using external fixation, four with...

Arthrodesis is used most commonly as a salvage procedure for failed total knee arthroplasty (TKA). For successful arthrodesis, a stable fusion technique and acceptable limb mechanical alignment are needed. Although the use of TKA intramedullary alignment rods may be helpful in terms of achieving an acceptable limb mechanical axis, fat...

Deep infection is one of the most devastating complications after knee fractures. It may be related to the initial fracture status or, more commonly, the surgical intervention. From 1991 to 2003, 12 patients underwent knee fusion to treat resistant infection after complex knee fractures or arthrodesis fractures using the Ilizarov...

We report the use of long curved Kuntscher nails to maintain stability during arthrodesis of nine infected and five uninfected failures of total knee replacement. The curvature of the nail helps positioning and avoids the need for cortical perforation. A single-stage operation was possible in most cases. Union rates are...

Procedures covered include Synovectomy of the knee, Total Knee Replacement (TKR), Revision Knee Arthroplasty, Distraction Arthroplasty, Arthrodesis of the knee,

A review of infections following TKR treated at two joint replacement centers identified 29 cases of resistant knee sepsis treated with a long intramedullary fusion nail. Clinical outcome and radiographs were reviewed at an average follow-up of 48 months
Intramedullary arthrodesis is a viable treatment for refractory infection after TKR. Patients...

Arthrodesis after the removal of a knee prosthesis is often hampered by the small area of contact of the bony surfaces and by pre-existing infection. Conventional systems of external fixation and compression frequently fail to achieve stability but the addition of the Wagner leg-lengthening apparatus applied anteriorly and adjusted to...

The recommended methods of achieving fixation for a knee arthrodesis following a failed knee replacement include external fixation or internal fixation using an intramedullary nail or plate. This is a retrospective review of 26 patients that had failed total knee replacements treated by knee arthrodesis occurring at a single institution...

Like elbow arthrodesis, knee arthrodesis is an option of last resort
Aims - Coapt 2 coplanar cancellous surfaces under compression with rigid fixation

Objectives: We evaluated the results of arthrodesis using a monolateral external fixator for the treatment of septic sequelae of the knee joint.
Conclusion: Knee arthrodesis using a monolateral external fixator is associated with a high fusion rate and a low complication rate, and provides a more comfortable treatment option compared to...

Discussion:
- IM may be most reliable technique for achieving union;
- w/ TKR infection, IM fusion needs to be performed in a staged fasion with removal of components and control of infection before fusion is attempted;
- contra indications:
 - active infection:
   - presence of active infection because of risk of infection spreading...
