The Histology of a Healed Superior Capsular Reconstruction Dermal Allograft: A Case Report
Acellular human dermal allograft commonly is used in the surgical treatment of complex rotator cuff tears, but little information is known about the biological fate of these grafts in human subjects. In this case report, the authors describe a patient who presented with a radiographically healed acellular human dermal allograft superior capsular reconstruction but had humeral head avascular necrosis. The healed superior capsular reconstruction, including graft −bone interfaces, was explanted after 7 months and sent for histologic analysis.
AbstractPurposeBone tunnel widening following anterior cruciate ligament reconstruction (ACLR) is well documented, although the aetiology and clinical significance of this phenomenon remain unclear. At mid-term follow-up, a greater prevalence of tunnel enlargement has been reported with the use of hamstring (HS) grafts. However, there are paucity of data on what happens in the longer term. The aim of this study was to assess the change in femoral and tibial tunnel dimensions 15 years after four-strand HS ACLR.MethodsThis is a retrospective review of 15 patients who underwent arthroscopic ACLR using HS autograft tendo...
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.
To assess the survivorship, clinical outcomes, and radiographic outcomes of patients who have undergone revision osteochondral allograft (OCA) to the knee in a retrospective case series.
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...
To report the subjective outcomes and objective stability in a series of chronically grade III posterolateral injured knees treated with a hamstring-based anatomic posterolateral corner (PLC) reconstruction technique using autografts.
ConclusionsFluid imbibition on postoperative MRI following osteochondral allografting of the knee is associated with the need for arthroscopic chondroplasty, but should not be interpreted as a sign of a failing graft.Level of evidenceLevel IV, Case Series.
ConclusionsMOW-HTO with autologous bone graft and β-TCP had the fastest radiological bone union and best clinical scores at 6 month follow-up.Level of evidenceRetrospective comparative study, Level III.
J Knee Surg DOI: 10.1055/s-0039-1681029We aimed to compare and analyze the outcomes of arthroscopic posterior cruciate ligament (PCL) reconstruction with the Achilles tendon allograft and the quadriceps tendon allograft. Twenty-nine patients who received the same procedure of arthroscopic PCL reconstruction within our inclusion criteria were reviewed retrospectively. There were 13 patients in the Achilles tendon allograft group and 16 patients in the quadriceps tendon allograft group. At least in 2 years of follow-up period, we evaluated the patients using the posterior drawer test, KT 2000 test, Lysholm knee scoring scale...
