A Randomized Trial of Autologous Chondrocyte Implantation Versus Alternative Forms of Surgical Cartilage Management in Patients With a Failed Primary Treatment for Chondral or Osteochondral Defects in the Knee.

Background: There are limited randomized controlled trials with long-term outcomes comparing autologous chondrocyte implantation (ACI) versus alternative forms of surgical cartilage management within the knee.

Purpose: To determine at 5 years after surgery whether ACI was superior to alternative forms of cartilage management in patients after a failed previous treatment for chondral or osteochondral defects in the knee.

Study Design: Randomized controlled trial; Level of evidence, 1.

Reduced chondrocyte viability is associated with the use of surgical marker pen ink.

Background: Sterile surgical marker pens are commonly used in cartilage repair surgery to aid in the placement of periosteal patches or collagen membranes in autologous chondrocyte implantation.

Purpose: To investigate the effects that methylene blue and crystal violet marker pen ink have on human chondrocytes when cultured on collagen membranes in vitro.

Study Design: Controlled laboratory study.

Posterior fracture dislocation of the hip from a Warrior turret injury.

Fracture of the femoral head after hip dislocation is a relatively rare injury and is often associated with a poor functional outcome. Most result from high impact motor vehicle accidents. We report the case of a soldier who trapped his foot in a traversing Warrior turret and suffered a severe abduction injury to his hip.

The role of local steroid injections in an operational field hospital setting.

Objectives: To assess the safety and effectiveness of administering local steroid injections in an operational field hospital environment.

Method: A prospective study of patients presenting to the physiotherapy department at the British Military Hospital (BMH) Shaibah, Iraq was undertaken from July 2006 - September 2006. Patients with a condition amenable to local steroid injection and who had not improved with conservative therapy were considered for the study.

Occult elbow dislocation: a rare cause of upper limb arterial insufficiency.

We present a case of vascular injury resulting from occult dislocation of the elbow joint. At last review 46 cases of brachial artery injury with concomitant dislocation have been reported (10), all in small series and case reports. In all the dislocation was clinically or radiologically evident.

Interlocking nailing of humeral shaft fractures: the Oxford experience 1991 to 1994.

Forty-three patients with fractures of the humeral shaft were treated by locked intermedullary nailing, using the Russell-Taylor nailing system. Overall there were few technical problems with nail insertion. Additional fracture comminution occurred in five patients but affected stability in only one case.

Errors in measurement of acetabular index.

Errors in determining the acetabular index can be induced either by incorrectly positioning the child for radiographs or by inter- or intraobserver errors. From postmortem radiographic studies, we have determined the magnitude of these errors. The error caused by pelvic rotation is +/- 3 degrees if the obturator foramina ratio is kept within 0.
