Purpose of this study was to assess postoperative laxity of MCL reconstructions utilizing a modified LaPrade superficial MCL reconstruction. We retrospectively reviewed post-operative valgus stress radiographs in 23 multiligament injured patients who underwent concurrent sMCL and cruciate ligament reconstruction by a single surgeon. Post- operatively, 23 patients underwent valgus stress radiographs that were assessed at a mean of 8.7 months (range 4-13 months), and mean SSD was 0.64mm ± 0.42mm. Eight patients underwent both pre- and post-operative valgus stress radiographs. Post-operative (0.09mm ± 0.63mm) SSD was found to be significantly reduced compared to pre-operative (2.07mm ± 0.44mm) SSD (mean diff. = 1.98mm, 95% CI = 0.72-3.24, P=0.007). Inter-observer reliability value for medial compartment gap measurement was 0.91 with a 95% confidence interval of 0.34- 0.97. In conclusion, presented technique results in excellent static stability of the knee as measured by valgus stress radiography at a minimum of 6 months postoperative. Level of Evidence IV.Mucoid degeneration (MD) of the anterior cruciate ligament (ACL) is a benign knee pathology, which is often indicated for surgical treatment if symptomatic. Most authors believe that partial ACL resection is the treatment of choice in symptomatic MD of the ACL. This study concerns complete ACL resection as a treatment of mucoid degenerated ACL. Thirteen patients were treated with complete ACL resection for symptomatic MD of the ACL from 2006-2016. Symptoms included limited range of motion (ROM) and posterior knee pain. Preoperative and postoperative results of eleven patient were compared. Postoperative recovery was four weeks on average. All patients (100%, n=11) reported an improvement in pain. All patients with a preoperative limited ROM (100%, n=9) reported a return to a normal (subjective) ROM. Eight patients (72.7%, n=8) reported an improvement of knee instability, while three patients (27.3%, n=3) experienced an unchanged knee stability. All patients (100%, n=11) reported a good to very good surgery satisfaction. Preoperative and postoperative KOOS questionnaires were compared and showed improvement in all categories. Complete resection of the ACL without ACL reconstruction is a reliable treatment for symptomatic cases of mucoid degenerated ACL.Overuse injuries of the knee are a common cause of missed training and competition days in elite cyclists, however the underlying conditions causing this knee pain are not well defined. We conducted a diagnostic study, investigating a consecutive series of 53 high level cyclists with non-traumatic knee pain over a 14 month period. Demographic data on the participants’ cycling specialty and training level was noted. Clinical information concerning knee pain intensity, location and occurrence were collected using a questionnaire. Our results show 7 different overuse injuries were identified. The prepatellar friction syndrome accounted for the majority of these overuse injuries (46%), while medial plica syndrome (15%), biceps femoris tendinopathy (7.5%), patellar tendinopathy (9.4%), infrapatellar plica friction syndrome (7.5%), infrapatellar fat pad impingement (5.7%) and iliotibial band syndrome (3.7%) were other causes of knee pain in these athletes. In contrast to current belief, our results show that instead of patellofemoral cartilage overload, friction related overuse injuries are the most frequent and underestimated cause of knee pain in high level cyclists.Total hip replacement surgery is the mainstay of treatment for end-stage hip arthritis. In 2014, there were 28227 procedures (incidence rate 252/100000 population). Using administrative data, we projected the future volume of total hip replacement procedures and incidence rates using two models. The constant rate model fixes utilisation rates at 2014 levels and adjusts for demographic changes. Projections indicate 32248 admissions by 2025 or an annual growth of 1.22% (incidence rate 273). The time trend model additionally projects the evolution in age-specific utilisation rates. 34895 admissions are projected by 2025 or an annual growth of 1.95% (incidence rate 296). The projections show a shift in performing procedures at younger age. Forecasts of length of stay indicate a substantial shortening. By 2025, the required number of hospital beds will be halved. Despite more procedures, capacity can be reduced, leading to organisational change (e.g. elective orthopaedic clinics) and more labour intensive stays.Total Hip Arthroplasty (THA) joint infection is an uncommon (0,3-1,7%) (20) but devastating complication after THA. While mostly caused by Gram-positive bacteria, with staphylococci and streptococci accounting for up to 76% of cases (21), orthopaedic surgeons are sometimes faced with atypical germs such as fungi or mycobacteria. We present a case of THA joint infection caused by Mycobacterium tuberculosis (MT) in a patient without a previous history of MT infection. A literature review was performed, and the treatment is discussed.The aim of this study is to determine the functional outcome and midterm survival rates of the Birmingham Hip Resurfacing and Birmingham Total Hip Arthroplasty. This retrospective, observational study included 150 surgeries (46 resurfacing procedures and 104 arthroplasty procedures) performed in 127 patients from 2005 to 2012. The Resurfacing and Arthroplasty study groups were evaluated with clinical (Harris Hip Score and Hip Disability and Osteoarthritis Outcome Score) and radiological follow-up. Cobalt and chromium levels were measured via blood samples. No revisions were required in either study group. Femoral stem osteolysis was observed in three patients in the Arthroplasty group. U0126 solubility dmso No osteolysis was observed in the Resurfacing group. Significantly higher clinical scores were observed in the Resurfacing group (p=0.04 and p=0.04, respectively). The average level of metal ions were similar in both groups. Both groups showed excellent midterm clinical and radiographic results with 100 percent survival rates. Additional follow-up is required to monitor future changes in blood metal ion levels.
