Early Failure of Primary Total Knee Arthroplasty Due to Massive Osteolysis Caused by Bio-Absorbable Interference Screws.

We report an unusual case in which an unabsorbed bio-absorbable screw in the tibial tunnel of anterior cruciate ligament reconstruction (ACLR) performed 11 years ago caused massive osteolysis and subsequent failure of total knee arthroplasty (TKA). ACLR was performed using suspensory fixation on the femoral side and a bio-absorbable interference screw on the tibial side. Fragmentation of the bio-absorbable screw at the time of tibial component implantation is thought to have evoked an accelerated inflammatory response, causing osteolysis, which finally resulted in early failure of the TKA.

Anterior Cervical Discectomy and Fusion with Stand-Alone Trabecular Metal Cages as a Surgical Treatment for Cervical Radiculopathy: Mid-Term Outcomes.

Study Design: Retrospective case cohort study done between 2002 and 2012.

Purpose: To assess the mid-term clinical and radiological outcomes of 1-level and 2-level anterior cervical discectomy and fusion (ACDF) with stand-alone trabecular metal cages.

Overview Of Literature: ACDF is the gold standard surgical treatment for cervical degenerative disease.

Multilevel lumbar spinal stenosis decompression: midterm outcome using a modified hinge osteotomy technique.

Study Design: A prospective cohort study was carried out looking at the functional outcome and post procedure translational segmental instability after multi-level lumbar decompression using a hinge osteotomy technique.

Objective: The hinge osteotomy technique involves unilateral subperiosteal muscle dissection with osteotomy of the base of the spinous processes, thereby preserving the integrity of the posterior elements. The objective of this study was to show the results of this technique clinically and radiologically.
