Nearly one-third of patients in this series with an ACL rupture requiring reconstruction had evidence of MPFL injury. This should be considered when patients are seen, and when MRI scans are reviewed/reported. The Medial Patello-Femoral Ligament (MPFL) is the largest component of the medial parapatellar ligamentous complex. The senior surgeon felt that there was an anecdotally high rate of MPFL injury amongst his patients undergoing Anterior Cruciate Ligament (ACL) repair, but no discussion of this in the present literature.Summary
Introduction
Osteolysis causing proximal femoral deficiency is a major problem in revision hip arthroplasty. Various methods including impaction bone grafting and bone allografts have been used to address this issue. We have analysed bone reformation using extended trochanteric osteotomy and distally fixed proximal hydroxyapatite-coated modular revision hip system (Stryker Restoration System) in 100 consecutive revisions by a single surgeon. Consecutive patients undergoing revision of femoral stem using posterior approach, extended trochanteric osteotomy and modular hip revision system were included in the study. Exclusion criteria were infection and loss of follow up. Paprosky grading system was used to assess bone loss. Standardized pre-op radiographs and follow-up radiographs at 6 weeks, 6 months and yearly post surgery were used for analysis. Minimum follow-up of 18 months (1.5–3.5 years). Bone reformation is quantified as definite reformation, some evidence of reformation and no bone reformation. Extended trochanteric osteotomy union rates and subsidence rates were also observed.Introduction
Method
The Signature system has been hailed as a new way to perform arthroplasty of the knee. It combines the accuracy in restoring mechanical axes of navigation with the convenience and familiarity of classical surgical techniques. With this comes the expectation that they should produce better functional results. In the literature, thus far, there is little data to corroborate this. The aim of this paper is to compare the early functional outcomes of this with the cemented AGC knee replacement system. Since April 2010, based on requirement, 25 patients underwent Signature knee replacements during this period for symptomatic degenerative or inflammatory arthritis with varying levels of deformity. Oxford functional scores were taken pre-operatively, at 6 weeks, 3 months and 6 months. These were then matched to an equal number of patients that had undergone an AGC knee replacement by the same surgeon. They were matched by pre-operative functional Oxford scores, age and gender.Introduction
