Our study examines a group of patients less than fifty years of age who underwent Total Elbow Arthroplasty with the Souter Strathclyde Elbow Replacement and compares their survivorship with a dataset of older group of patients.

309 patients were who underwent standard long stemmed Souter Implants as a primary procedure for rheumatoid arthritis over the last 16 years were included in this study. Patients were divided into two groups according to the their age at the time of surgery. In the first group of older patients greater than or equal to 50 years of age (Mean Age =64.4 years) there were 263 patients with a mean follow up of 7.3 years. The second group consisted of patients less than 50 years of age (Mean Age 42.04 years) who had a longer mean follow up period of 9.3 years. The survivorship of the implants for three different failure events was compared for both groups. The radiographs were evaluated using the Kaplan-Meir survival analyses, to produce survival curves for revision, revision due to aseptic loosening of the humeral component and finally gross loosening of the humeral implant (Hidex> 1). For each terminal event there were two curves and the age group analyses were all non-significant when log rank tested. The rates of loosening/revision were comparable in all curves.

We set out to determine the role of age as predictive factor for loosening. Our conclusions were that Total Elbow Arthroplasty is suitable for younger patients with rheumatoid elbow. Using survivorship data there does not appear to be any difference in loosening when compared to patients of an older age group. As previously published the position of the humeral component within the humerus is crucial for long-term survivorship. Thus age alone should not be the sole discretionary factor for withholding the benefits of elbow Arthroplasty in younger patients.

We report a rare case of an intracortical chondroma in the region of the medial femoral condyle of the femur extending into the femoral sulcus and the patellofemoral joint.A sixteen year old Asian boy presented with repeated episodes of right sided anterior knee pain and giving way over a three year period. The patient had been treated previously for multiple bony swellings at another hospital and a diagnosis of multiple enchondromatosis had been made. Examination revealed that the patellofemoral compression test was positive with fullness over the medial eminence of the femur in the region of the trochlear groove.Pre-operative X-rays and MRI scan showed the presence of an intracortical lesion over the medial femoral condyle extending into the femoral sulcus. The lesion demonstrated intermediate signal intensity on T1 and high intensity on T2 weighted images with variable low signal intensity foci due to the presence of a calcified matrix. The patient underwent arthroscopic examination. An intra-articular lesion (2cmx 3cm.) was identified and excised through a mini-arthrotomy. The lesion was entirely intra-articular arising from the medial femoral condyle proximal to the femoral sulcus, extending partially into the supra-patellar pouch. Histopathological examination confirmed the presence of a low grade cartilaginous neoplasm best diagnosed as an atypical chondroma. At a two year follow up appointment the patient was found to be asymptomatic with no evidence of radiological recurrence.

Although there have been several reports of periosteal chondromas developing around the knee the majority deal with soft tissue chondromas in para-articular locations or intra-cortical tumours in extra-articular regions. Our tumour is unique due to its intra-articular and intracortical location. A detailed review of the literature of this rare tumour is presented with a pictorial presentation of the case including arthroscopic radiological and histopathological findings.
