We present 10–15 year follow-up of 33 patients who underwent Elmslie-Trillat osteotomy for severe patellar subluxation or dislocation. In the literature it has been reported that tibial tubercle osteotomy predisposes to subsequent patella-femoral arthritis, however it has never been documented if pre-existent knee chondral damage has any role in this development. In our group all patients had pre-op knee arthroscopy performed and extant of chondral damage was documented. We preformed an evaluation by long-term follow-up to determine weather pre-op chondral damage was the cause of subsequent osteoarthritis of patella-femoral joint. All patients were invited to attend outpatient clinic for clinical examination and knee radiographs and assessed by an independent research surgeon. Mean age at follow-up was 43 years and average follow-up was 10.5 years (range 10–15 years). 90% follow-up was achieved. Knee function was assessed by clinical scores (Lysholm knee score, American Knee Score, Oxford Knee score, Tegner and Insall knee scores) and three radiographs (AP, Lateral and Merchant views). Four patients had developed significant arthritis and underwent joint arthroplasty. Majority of patients reported good results with no further dislocation. However we noticed that extant of pre-op chondral damage was a significant factor in subsequent development of patella-femoral arthritis. We will present our data which is unique as no previous such long-term results have been reported for tibial tubercle transfers followed-up for more than 10 years and have pre-op arthroscopic documented chondral damage.

We present a retrospective analysis of 50 cases of cuff tear arthropathy, treated over past seven year period by use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3 years. Mean (SD) age was 81.3 (9.2) years and female to male ratio was 5:1. Six patients had bilateral reverse geometry shoulder replacements. Patients were assessed with preoperative Oxford and American Shoulder and Elbow Scores Society score (pre-op ASES) and post-operative American Shoulder and Elbow Society Score (post-op ASES), Oxford, Constant and SF36 scores. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P< 0.001, Paired t-test). Mean post operative Oxford score was 27.25 (95% CI: 18.4 – 27.6). Mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). X-ray review was performed to assess scapular notching and Sirveaux score was used to grade extent of notching. 11 patients had Sirveaux grade 0, 5 had grade 1, 6 had grade 2, 12 had grade 3 and 8 had grade 4 notching. Intra-operative complications included 2 glenoid fractures. Post-operative complications included 2 acromion fractures and 2 episodes of subsidence with dislocation. None of the patients developed post operative haematoma. There was one episode of infection in one patient that required further surgery. Iteration of approach with increasing experience over the years will be discussed. Ours is the biggest series of reverse geometry prosthesis used for irreparable rotator cuff tear arthropathy published so far in the literature and our results have shown superior results in terms of improvement in function and complications. We conclude reverse geometry shoulder replacement provides reasonable improvement in pain and function in elderly population with massive cuff tear arthropathy of shoulder.

We present a retrospective review of 50 cases of cuff tear arthropathy treated over past seven years by the use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3.04 years. Mean age was 81.3 (SD 9.2) years, female to male ratio was 5:1 and seven patients had bilateral procedures. Pre-operatively patients were assessed with American Shoulder and Elbow Surgeons Scores (ASES) and Oxford Scores and pos-operatively with ASES, Oxford and Constant scores. SF36 score was used to assess functional health status. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P< 0.001, Paired t-test). Mean post-operative Oxford score was 27.25 (95% CI: 18.4 – 27.6) and mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). Sirveaux score was used to grade extent of glenoid notching on AP and lateral glenohumeral views, that showed 69% had notched. Complications included two acromion fractures, two episodes of subsidence with dislocation, one episode of infection and one patient with unexplained pain in axilla. We found reverse geometry shoulder replacement provides reasonable improvement in pain and function in elderly patients with massive cuff tear arthropathy.
