“…Use of the peroneus longus tendon autograft for lateral meniscus replacement is possible because the size and biomechanical characteristics of the peroneus longus tendon autograft are similar to that of the native meniscus, making this transplantation procedure promising and safe. 14 The suggested technique is easier in comparison with allotransplantation of the meniscus. It uses standard preparation and harvesting techniques and can be performed using standard procedures and knee and shoulder instrument sets.…”

“…Biomechanical requirements (130-150 megapascal on average) can be met by compression load of the peroneus graft. 14 The main indications for our procedure are similar to allograft transplantation and meniscus scaffolds implantation: lateral pain syndrome after lateral meniscectomy in young patients without significant osteoarthritic changes. It is possible to perform this procedure for patients with nonsignificant malalignments and stable knee.…”

Nowadays, several techniques are available for preserving the lateral aspect of the knee after meniscectomy; meniscus transplantation is the gold standard, and meniscus scaffold implantation is an effective alternative. However, meniscus transplantation is technically difficult and has many potential complications, whereas scaffolds resorb over time. Autografts are commonly used for labroplasty in shoulder and hip surgeries. We attempted to adapt this technique to the knee, using autografts for meniscus replacement. In this report, we describe a meniscus-replacement technique, using a peroneus longus autograft, for lateral meniscus deficits. This technique significantly simplifies the procedure and is cost effective, and thus can be considered as an alternative technique for preventing osteoarthritis of the lateral aspect of the knee.

“…Ex vivo testing of human tendons has also demonstrated uncertainty in the effect of age on mechanical properties. While most mechanical properties are unaffected by age, moderate correlations between decreased mechanical properties and age have been observed [11][12][13]. These studies measured viscoelastic and quasi-static, but not dynamic, properties.…”

Tendon injuries increase with age, yet the age-associated changes in tendon properties remain unexplained. Decorin and biglycan are two matrix proteoglycans that play complex roles in regulating tendon formation, maturation, and aging, most notably in extracellular matrix assembly and maintenance. However, the roles of decorin and biglycan have not been temporally isolated in a homeostatic aged context. The goal of this work was to temporally isolate and define the roles of decorin and biglycan in regulating aged murine patellar tendon mechanical properties. We hypothesized that decorin would have a larger influence than biglycan on aged tendon mechanical properties and that biglycan would have an additive role in this regulation. When decorin and biglycan were knocked down in aged tendons, minimal changes in gene expression were observed, implying that these models directly define the role of decorin and biglycan in regulating tendon mechanical properties. Knockdown of decorin or biglycan led to minimal changes in quasi-static mechanical properties. However, decorin deficiency led to increases in stress relaxation and phase shift that were exacerbated when coupled with biglycan deficiency. This study highlights an important role for decorin, alone and in tandem with biglycan, in regulating aged tendon viscoelastic properties.

“…7,31,49,51,53 Previous studies have demonstrated an age-related decline in the biomechanical proprieties of human ACLs and Achilles tendons. 7,40,53 This may be an issue to consider when using a degenerated graft that might influence postoperative graft maturation of ACL reconstructions in older patients. Regarding the age of the graft donor, some surgeons have advocated harvesting tissue from younger donors on the premise that they will have stronger tissue and, thus, improved clinical results.…”

Influence of Age on Signal Intensity of Magnetic Resonance Imaging and Clinical Outcomes in Double-Bundle Anterior Cruciate Ligament Reconstruction: Comparisons Among Different Age Groups

et al. 2021

Background: Thus far, the clinical results of anterior cruciate ligament (ACL) reconstruction have been observed to be comparable between young and older patients. In contrast, age-related changes in the structural and mechanical properties of tendons used for autografts have been described. However, age-related changes associated with graft maturation remain poorly understood. Hypotheses: The hypotheses of this study were that (1) clinical outcomes after ACL reconstruction would be comparable between younger and relatively older patients and (2) younger patients would show lower signal intensity changes on magnetic resonance imaging scans indicative of graft maturation that would be better than that in relatively older patients. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively evaluated 236 patients who underwent double-bundle ACL reconstruction via the outside-in technique using hamstring autograft between January 2012 and December 2015. The patients were categorized by age into 3 groups: <20 years old, 20 to 39 years old, and ≥40 years old. Clinical outcomes were evaluated using the subjective International Knee Documentation Committee (IKDC) score, Tegner activity scale, Lysholm score, and objective assessment of joint laxity 24 months after surgery. In addition, graft maturation was evaluated using magnetic resonance imaging–derived measures of the signal intensity ratio (SIR) at 3, 6, 12, and 24 months postoperatively. Clinical outcomes and graft maturation were compared among the 3 groups. Results: The SIR of both bundles increased from 3 months to 12 months and decreased by 24 months, showing the same tendency in all groups. No significant difference was found in the SIR among the 3 groups at any time point ( P > .05). The IKDC score was significantly lower in the ≥40-year group than in the <20-year group ( P < .01). In contrast, no significant differences were noted in other clinical outcomes. Conclusion: Patients aged ≥40 years exhibited lower IKDC scores compared with younger patients, although the results of graft maturation were comparable.
