The point estimates suggests about 25-50% lower risk of consultation for knee OA after meniscus repair as compared to APM. However, the consultation rate for knee OA after repair was still at least two times higher as compared to the general population.

Background and purposeSeveral randomized controlled trials have not shown any added benefit of arthroscopy over placebo surgery or physiotherapy in middle-aged patients with knee symptoms without trauma. We studied the characteristics of the knee arthroscopies performed in southern Sweden.Patients and methodsFrom the orthopedic surgical records from 2007–2009 in the Skåne region of Sweden (with a population of 1.2 million), we retrieved ICD-10 diagnostic codes and selected all 4,096 arthroscopies that were diagnosed peroperatively with code M23.2 (derangement of meniscus due to old tear or injury) or code M17 (knee osteoarthritis). We extracted information on cartilage and meniscus status at arthroscopy, and we also randomly sampled 502 of these patients from the regional archive of radiology and analyzed the preoperative prevalence of radiographic or magnetic resonance imaging (MRI)-defined osteoarthritis.Results2,165 (53%) of the 4,096 arthroscopies had the diagnostic code M23.2 or M17. In this subgroup, 1,375 cases (64%) had typical findings consistent with degenerative meniscal tear (i.e. that correspond to a degenerative meniscal tear in at least a third of all arthroscopies). Of the randomly sampled patients, the preoperative prevalence of radiological knee osteoarthritis was 46%.InterpretationThere is a discrepancy between evidence-based medicine treatment guidelines and clinical practice regarding the amount of knee arthroscopies performed in patients with symptoms of degenerative knee disease.

Objective To assess the impact of the Swedish health authority recommendation against the use of knee arthroscopy in patients aged ≥40 years with knee osteoarthritis (OA). Design Interrupted time series analysis. Setting Public health care in Skåne region. Participants Patients aged ≥40 years who underwent knee arthroscopy from January 2010 to December 2015. Intervention(s) National guideline’s recommendation against the use of knee arthroscopy in patients with knee OA. Main Outcome Measure(s) 1) proportion of patients aged ≥40 years with a main diagnosis of Knee OA and/or degenerative meniscal lesions (DML) who underwent knee arthroscopy, and 2) overall knee arthroscopy rate per 100,000 Skåne population aged ≥40 years. Results A total of 6,155 knee arthroscopy were performed among people aged ≥40 years during study period. Of 42,044 patients with Knee OA/DML, 3,728 had knee arthroscopy. The recommendation was associated with reductions in the use of knee arthroscopy and two years after the recommendation, there was a reduction of 28.6% (95% CI: 9.3, 47.8) and 34.7% (23.9, 45.4) in proportion of Knee OA/DML patients with knee arthroscopy and the overall knee arthroscopy rate, respectively, relative to that expected if pre-recommendation trend continued. Our sensitivity analysis showed that the use of total knee replacement was stable over the study period. Conclusion The national recommendation was associated with reduction in use of knee arthroscopy in public health care in southern Sweden. However, still 4.5% of these patients underwent knee arthroscopy in 2015 implying that more efforts are required to achieve the recommended target.

The good Achilles Tendon Total Rupture Score in the nonsurgically managed group, together with the relatively low rate of re-ruptures and other complications in these patients, makes this treatment a preferable option for most patients. However, the tendency for a lower re-rupture rate and better performance on the heel-raise test in surgically treated patients suggest surgery may be beneficial in selected patients.

Introduction: Ankle fractures are commonly treated by open reduction and internal fixation with plate and screws. Unplanned return to theatre is common, in many cases to extract prominent osteosynthesis material from the lateral malleolus as swelling subsides. We hypothesised that patients operated with a posterolateral plate placement on the lateral malleolus would have fewer reoperations, and fewer complications, compared to patients with a lateral plate placement.Materials and Methods: From a prospectively collected database of all orthopaedic surgery performed at our institution, we identified 664 ankle fractures undergoing plate fixation between 2008-01-01 and 2012-04-30. Radiographs were analysed to only include AO/OTA 44-B-fractures (n = 453), and to define study groups based on plate positioning. Hospital files were assessed to identify possible confounding factors, and any unplanned reoperation or complication. Complications were classified according to Dindo-Clavien. Results:The risk of reoperation was 13% after posterolateral plating, compared with 24% after lateral plating; absolute risk reduction 10% (95% CI: 2.5-18), p = 0.02. After adjusting for possible confounders, the odds ratio of undergoing reoperation after lateral plating was 2.2 (95% CI: 1.17-4.1), p = 0.01. The two surgical methods did not differ with regard to complication frequency: 31% vs 34%, p = 0.6, but complications following lateral plate fixation were more serious, p = 0.03. Plate positioning depended on surgeon preference. Discussion: The two studied methods are both considered standard treatment of ankle fractures, and relatively simple surgical procedures. High rates of secondary surgery after plate fixation have been reported, but no study comparing plate positioning has been previously published to our knowledge. AO Sweden has recently switched to teaching posterolateral plating in group exercises during the AO Basic Fracture Surgery course, based on the belief that it may be safer than lateral plating. Our findings support this change in practice.Conclusions: Posterolateral plate positioning on the lateral malleolus in AO/OTA 44-B-fractures may be preferential to lateral plate positioning, due to a large difference in unplanned secondary surgery.
