Perception of ACL injury prevention programs amongst professional netball players and coaches has not been studied. We investigated (1) level of awareness and experience of ACL injury prevention programs; (2) use of ACL injury prevention programs; and (3) barriers to implementing ACL injury prevention program in netball. Female netball players representing Welsh senior and under-21 teams and elite and amateur coaches were invited electronically to this web-based study between 1st May–31st July 2021. Information on ACL injury susceptibility and seriousness, knowledge, experience, and implementation of ACL injury prevention programs were ascertained.Abstract
Introduction
Methodology
Recently biodegradable synthetic scaffolds (Trufit plug) have provided novel approach to the management of chondral and osteochondral lesions. The aim of this study was to assess our 2 year experience with the Trufit plug system. 22 patients aged 20 to 50 years old all presenting with knee pain over a 2 year period were diagnosed either by MRI or arthroscopically with an isolated chondral or osteochondral lesion and proceeded to either arthroscopic or mini arthrotomy Trufit plug implantation. In 5 patients plug implantation was undertaken along with ACL reconstruction (3), medial meniscal repair (1) and contralateral knee OCD screw fixation (1). Pre and post operative IKDC scores were obtained to assess change in knee symptoms and function. At a mean follow up of 15 months (range 2 – 24 months) improved IKDC scores were achieved with the scores improving with time. 2 patients have had a poor result and have had further surgery for their chondral lesions. One patient had failure of graft incorporation at second look arthroscopy and went onto to have a good result after ACI. The second patient had good graft incorporation on second look but had progression of osteoarthritic degeneration throughout the other compartments of the knee which were not initially identified at the time of Trufit plugging. We conclude that Trufit plug is an alternative method for managing isolated chondral and osteochondral lesions of the knee which avoids harvest site morbidity or the need for staged surgery.
Involvement of Patellofemoral joint (PFJ) has significant bearing in the management of osteoarthritis of the knee. The aim of this study is to assess the relationship between skyline radiographs, MRI and arthroscopic findings in the patellofemoral joint. Data was collected prospectively from fifty-three patients who underwent arthroscopy. There were 36 males and 17 females in the group with mean age of 48 years (range 18-71). Arthroscopically PFJ arthritis was classified based on Outerbridge grading system. Patients with Outerbridge grade III and IV lesions were considered to have significant arthritis of the PFJ. Kellgren-Lawrence grading system was used to assess the skyline radiographs. Radiographically patients with grade III and IV Kelgren-Lawrence changes were considered to have significant osteoarthritis of the PFJ. MRI scans were also studied to assess involvement of PFJ. Thirty-two patients had MRI scan and 20 patients had skyline views done as part of preoperative work up. Arthroscopic findings were considered as gold standard. MRI scan had specificity of 75%, sensitivity of 81%, positive predictive value of (PPV) 77 and negative predictive value of (NPV) 80% in diagnosing significant PFJ arthritis. Skyline radiographs had specificity of 100%, sensitivity of 50%, PPV of 100% and NPV of 57%. The overall accuracy of skyline radiographs in predicting significant PFJ arthritis was 70% and for MRI was 78%. We conclude that skyline radiographs has some value in he diagnosis of PFJ arthritis, however the sensitivity and negative predictive value is very is poor.
We aimed to determine the reliability, accuracy and the clinical role of digital templating in the pre-operative work-up for total knee replacement. Initially a sample of ten pre-operative digital radiographs were templated by four independent observers to determine the inter- and intra-observer reliability of the process. Digital templating was then performed on the radiographs of 40 consecutive patients undergoing total knee replacement by a consultant surgeon not involved with the operation, who was blinded to the size of the implant inserted. The Press Fit Condylar Sigma Knee system was used in all the patients. The size of the implant as judged by templating was then compared to that of the size used. Good inter- and intra-observer agreement was demonstrated for both femoral and tibial templating. However, the correct size of the implant was predicted in only 48% of the femoral and 55% of the tibial components. Albeit reproducible, digital templating does not currently predict the correct size of component often enough to be of clinical benefit.
