Self-reported and performance-based outcomes following medial patellofemoral ligament reconstruction indicate successful improvements in knee stability after surgery despite remaining limitations in knee function

AbstractPurposeTo evaluate short- to midterm outcomes of medial patellofemoral ligament reconstruction (MPFL) using patient-reported outcome measures and functional testing.MethodsTwenty-four patients were examined regarding knee function after MPFL reconstruction, with a mean follow-up time of 45.3  ± 18.4 months since surgery. Knee function was evaluated using the Tegner score, VAS, the knee injury and osteoarthritis outcome score (KOOS), the Lysholm score, SF-36 and EQ-5D-3L as well as functional scores. A group of uninjured persons of the same age and same gender composition was used for comparison.ResultsEight (40%) patients managed to return to their pre-injury activity level. Five (25%) patients stated that they had experienced further patella dislocations after surgery but only two (10%) had sought medical help. Patients showed significantly poorer results in all PROMs compared to controls. The results obtained with SF-36 showed significant differences in physical health between the groups, but not in mental health. The functional performance test results showed overall poorer results for the patients versus controls: 11.5 sets for the square jump (6.7 –15.7) versus 21 sets (18–26), 11.5 sets for the step-down test (6.5–15) versus 22 sets (18–26), and 77 cm for the single-leg hop for distance (32.2–110.5) versus 126 cm (115–37); all (P

These injuries are common among the young population of the society and are significant causes of morbidity and functional impairment. Arthroscopic ACL Reconstruction (ACLR) is considered as a gold standard in the management of ACL injuries. ACLR has been shown to restore the joint stability, and improve the functional outcome. Nevert...

AbstractPurposeThe purpose of this study was to report the long-term outcomes of a continuous series of patients who underwent simultaneous anterior cruciate ligament (ACL) reconstruction and opening wedge high tibial osteotomy (HTO) for varus-related early medial tibio-femoral osteoarthritis. It was hypothesized that this combined surgery sustainably allowed return to sport with efficient clinical and radiological results.MethodsFrom 1995 to 2015, all combined ACL reconstruction (bone-patellar tendon-bone graft) and opening wedge HTO for anterior laxity and early medial arthritis were included. Clinical evaluation at fina...

ConclusionsRotating hinge total knee arthroplasty using a single modular implant shows acceptable survival rates and function compared to previous studies with (re-)infection being the most relevant mode of failure. Patients with a high CCI and multiple previous surgeries are at increased risk for failure.Level of evidenceRetrospective cohort study, III.

AbstractPurposeA few new criteria for early detection and prevention of early knee osteoarthritis (EKOA) have been proposed. However, its prevalence, risk factors, relationship with function and prognosis have not been clarified. The purpose of this study was to investigate the prevalence of EKOA and its risk factors in the Japanese general population.MethodsA total of 1104 volunteers (443 males, 661 females) who participated in the Iwaki cohort study in Japan were enrolled in this cross-sectional study. Their bilateral weight-bearing anterior –posterior knee radiographs were classified by Kellgren–Lawrence (KL...

AbstractPurposeBi-cruciate-retaining total knee arthroplasty (BCR-TKA) is recognized as an alternative to the cruciate-retaining total knee arthroplasty (CR-TKA) within the pursuit of retrieving the “forgotten artificial knee joint”. The aim of this study was to provide a short-term comparison in functional and clinical outcomes between BCR- and CR-TKA.MethodsThe cohort consisted of 61 BCR-TKA patients, matched with 61 suitable CR-TKA patients, and operated between 2014 and 2016 due to osteoarthritis. Patient-reported outcome measurements were assessed preoperatively and at 3, 12, 24 and 36 months postoperative...

FreedmanAbstractVertical flap tears, or parrot beak flap tears, are oblique tears of the meniscus thought to originate as a central radial tear and propagate longitudinally towards the periphery, generating a partially detached unstable fragment that can subsequently displace into the meniscal recess. Although magnetic resonance imaging (MRI) is frequently used to diagnose and characterize meniscus pathology, imaging findings for displaced flap tears are not well desc...

Authors: Trăistaru MR, Kamal D, Maria DT, Zorilă MV, Alexandru DO, Rogoveanu OC, Radu M, Kamal KC Abstract Knee osteoarthritis (KOA) is a very common, slowly progressive and incurable articular disease resulting in the breakdown of cartilage and bone in the joint, which causes significant discomfort, pain and disability, with a significant socio-economic impact. The aim of our observational study for patients with symptomatic KOA was to investigate the changes of C-terminal telopeptide of type II collagen (CTX-II) in serum pre and post a complex rehabilitation program and to establish the correlation between all ...

ConclusionThe diagnostic benefits of SPECT/CT in the challenging and complex cohort of patients with pain after primary TKA have been proven. The excellent sensitivity and specificity for detection of tibial or femoral component loosening and diagnosis of patellofemoral OA have been surgically confirmed. Due to the benefits in establishing the correct diagnosis, SPECT/CT should be implemented as part of the routine diagnostic algorithm for patients with pain after primary TKA.Level of evidenceII.

ConclusionThis systematic review found that the use of HTO for ACLR revision produces good post-operative functional outcomes, low complication rates, and no reported re-ruptures. The main indications for combined HTO with ACLR revision was a posterior slope of more than 12 ° or severe varus malalignment. Future studies with large sample sizes and long-term follow-up are required to corroborate these results.
