Progression of radiographic osteoarthritis after partial meniscectomy in degenerative medial meniscal posterior root tears was greater in varus- than in neutral-aligned knees: a minimum 5-year follow-up

AbstractPurposeTo perform a radiographic assessment of osteoarthritis, progression after partial meniscectomy (PM) in degenerative medial meniscus posterior root tears (MMPRTs) in relation to preoperative mechanical axis (MA). The hypothesis is that neutral-aligned knees with degenerative MMPRTs have better radiographic outcomes than those of varus-aligned knees after arthroscopic PM.MethodsRecords of 114 patients with degenerative MMPRTs and Kellgren –Lawrence (KL) grade ≤ 2 osteoarthritis, who underwent PM, had preoperative weight-bearing hip-to-ankle radiographs from 2004 to 2014, and were followed-up for at least 5 years were reviewed retrospectively. The mean follow-up period was 8.3 ± 2.8 years. Preoperative MA values were used to classify the patients into either a Neutral (N valgus 3° to varus 3°;n = 60) or Varus-aligned group (V varus>  3°;n = 54). Joint space width (JSW; mm) and KL grade (0/1/2/3/4) were measured preoperatively and finally on weight-bearing 45° flexion posteroanterior and anteroposterior radiographs, respectively.ResultsPreoperative JSW and KL grade did not differ significantly between the groups (N vs V; JSW 3.64  ± 0.83 vs 3.44 ± 0.81,P = 0.201; KL grade, 2/31/27/0/0 vs 0/22/32/0/0,P = 0.162); however, the final JSW and KL grade differed significantly between the groups (N vs V; JSW 3...

J Knee Surg DOI: 10.1055/s-0040-1702191The aim of this study was to investigate radiographic factors relevant to predict surgical outcomes of arthroscopic partial meniscectomy (APM) in elderly patients with mild osteoarthritis (Kellgren–Lawrence grades 1 and 2). Data of 172 consecutive patients aged>70 years who underwent arthroscopic meniscal surgery were reviewed retrospectively. The patients who met the inclusion criteria were classified into two groups based on the minimal clinically important difference value of the Lysholm knee scoring scale comparing the score of the last visit with that of the preoperative...

ConclusionThis study demonstrated that the AUC for the surgical treatment of knee OA can be applied easily in a clinical setting. Most of the treatments provided at our institution were appropriate and in agreement with the AUC recommendations. Additionally, the AUC had a web-based application that was easy to use and simple for identifying treatment recommendations.Level of evidenceRetrospective study, level IV.

AbstractPurposeThe purpose of this study was to examine the predictive value concerning clinical outcome and implant survival, as well as the accuracy of individual tests of a recently published radiographic decision aid for unicondylar knee arthroplasty indication findings.MethodsIn the retrospective part of the study, 98 consecutive patients who had undergone unicondylar knee arthroplasty (Phase 3 Oxford medial UKA) were included, using revision questionnaires, as well as the Forgotten Joint Score-12 (FJS-12) and Knee Osteoarthritis Outcome Score (KOOS) and analysed for suitability of the radiographic decision aid. Inapp...

AbstractPurposeThe purpose of this study was to analyze the long-term clinical and radiological outcomes of patients who underwent closing-wedge High Tibial Osteotomy (HTO) for the treatment of medial compartment osteoarthritis and to evaluate the conversion rate to knee arthroplasty.MethodsA retrospective, non-randomized, monocentric study was performed in our Institution considering 166 patients between 1989 and 2012. The final population was composed by 82 patients (94 knees), median age at time of operation was 53 (range 45 –73) years. All patients were evaluated clinically (HSS Score, Tegner Scale, VAS and Crosb...

ConclusionPoor preoperative WOMET scores, presence of cartilage lesions at the medial femoral condylus, meniscal degeneration, concomitant anterior cruciate ligament lesions as well as lateral meniscal tears are correlated with worse postoperative outcomes after arthroscopic partial meniscectomy. Patients with femoral bone marrow lesions femoral are more likely to gain benefit from arthroscopic partial meniscectomy in the middle term. Despite justified recent restrictions in indication, arthroscopic partial meniscectomy seems to effectively reduce pain and alleviate symptoms in carefully selected patients with degenerative...

ConclusionACL reconstruction provides satisfactory knee stability. The risk of subsequent osteoarthritis depends chiefly on the status of the menisci. Residual laxity is also associated with the development of osteoarthritis.Level of evidenceIV, retrospective cohort study.

ConclusionThe findings of this study partly confirm the hypotheses that pain and functional impairments after TKA without patellar resurfacing are associated with patellar shape. No association was revealed between postoperative patellar orientation and function nor pain. Quantitative consideration of patellar congruency could therefore prevent pain and improve function after TKA without patellar resurfacing.Level of evidenceRetrospective study, Level III.
