Spontaneous osteonecrosis of the knee: what do we know so far? A literature review

ConclusionsAlthough the aetiology of SONK remains unknown, there are many treatment options, and the choice of the most suitable one is challenging. We think that subchondroplasty may be one of the effective methods.

ConclusionThe present study revealed novel risk factors for SSI after HTO that previous studies have failed to find, including use of artificial bone graft and longer anaesthesia duration; primary diagnosis of osteonecrosis and younger age were novel protective factors. These findings will help surgeons assess risks of SSI after HTO in individual patients.Level of evidenceIII.

ConclusionsLigament stabilization with arthroscopic procedures for individuals with chronic ankle instability and medial ankle OA yielded significant functional outcomes with high patient satisfaction, even without radiographic improvement.Level of evidenceIV.

Meniscus allograft transplant (MAT) is traditionally not recommended for patients with moderate to severe osteoarthritis. We hypothesize that clinical and graft survival of MAT will not be impacted by the severity of cartilage damage assessed by Outerbridge (OB) grade at the time of surgery, if the damaged cartilage is also treated.

AbstractPurposePainful and slow recovery are the presumed disadvantages after opening-wedge high tibial osteotomy (HTO) and play a role in favouring arthroplasty as treatment for moderate isolated medial knee arthritis. The primary study objective was to investigate the effect of press-fit structural impacted bone allograft with locking plate fixation on early ambulation, postoperative pain levels, and resumption of daily-life activities in opening-wedge HTO.MethodsA prospective consecutive opening-wedge HTO case series was conducted, including 103 patients with final follow-up at 1  year. Weight-bearing was allowed f...

ConclusionBimeniscal replacement by an allograft and/or substitute provides good short-term functional and anatomical outcomes. Nevertheless, this procedure is warranted only in highly selected patients.Level of evidenceIV, retrospective study.

ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.

ConclusionsUsing non-irradiated allografts for one-stage reconstructions of all the injured ligaments in MLKIs is effective and safe. Anteroposterior stability was difficult to restore, but patients returned to their daily activities and sometimes to their sports activity at the same preinjury level.Level of evidenceLevel IV, case series.

Fresh osteochondral allografting has gained popularity as a useful technique for managing difficult cartilage repair problems and, in revision situations, is a treatment of choice when other procedures such as microfracture, osteochondral autograft transfer, and cell-based therapies fail. However, it is a challenge when an allograft fails. Absent substantial progression of osteoarthritis, revising with another allograft results in a reasonable chance of "success" (but a high likelihood of further surgery along the way).

J Knee Surg DOI: 10.1055/s-0039-1695040Patellar bone–tendon–bone (pBTB) autografts are often considered the “gold standard” for complete anterior cruciate ligament (ACL) reconstruction and are also associated with significant complications and early-onset knee osteoarthritis (OA). A novel quadriceps tendon allograft with synthetic augmentation, or “internal brace” (QTIB), has been reported to have potential advantages for ACL reconstruction based on animal model data. In this preclinical canine comparison study, we hypothesized that QTIB allograft compared with pBTB autograft would provi...

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...
