Short-term results of tibial interference screw fixation for transtibial medial meniscus posterior root pull-out repair. J Orthop 2024; 50:155-161. [PMID: 38229771 PMCID: PMC10788779 DOI: 10.1016/j.jor.2023.12.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 12/28/2023] [Accepted: 12/30/2023] [Indexed: 01/18/2024] Open
Abstract
Background To evaluate the technique of transtibial pull-out repair with tibial interference screw fixation for medial meniscus posterior root (MMPR) tear by reporting on short-term outcomes and complications. Methods All MMPR repairs performed between January 2019 and August 2021 (n = 70) were retrospectively screened regarding demographic data and surgical parameters. The patients were questioned for performed revision surgery, symptoms and complications. The Numeric Rating Scale (NRS) for pain, Lysholm Knee Score and International Knee Documentation Committee Subjective Knee Form (IKDC) questionnaires were used to evaluate clinical outcome. In cases of revision surgery for re-tear the mode of failure was intraoperatively classified (patients with re-tear were excluded from the clinical follow-up examination). The influence of demographic and treatment parameters (surgical and rehabilitation) on the incidence and mode of re-tear and clinical scores was evaluated. Results After 2.3 ± 0.7 years, 62 patients (88.6 %) were available for follow-up. There were no direct intra- or postoperative complications. No revision was performed due to symptoms related to the tibial fixation material. The mean surgery time was 33.5 ± 10.8 min. The overall re-tear rate was 17.7 % (11 patients) of whom 10 were treated surgically and one conservatively. Primary mode of failure was suture cut-out from the meniscus (70 %). The NRS, Lysholm Knee Score and subjective IKDC were obtained in 38 patients and improved from 6.8 ± 2.4, 40.1 ± 23.9 and 32.8 ± 16.3 to 2.2 ± 2.2, 80.5 ± 16.3 and 63.0 ± 13.9, respectively (all p < 0.001). No influence was observed from demographic and treatment parameters on re-tear rates or clinical Scores. Conclusions Tibial interference screw fixation is a fast and promising technique for MMPR transtibial pull-out repair. In the presented technique, utilizing non-absorbable locking sutures alongside tibial interfenrence screw fixation, the primary mode of failure was suture cut-out from the meniscus.

Age influence on resistance and deformation of the human sutured meniscal horn in the immediate postoperative period. Front Bioeng Biotechnol 2024; 11:1249982. [PMID: 38249802 PMCID: PMC10796521 DOI: 10.3389/fbioe.2023.1249982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 12/18/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction: To preserve knee function, surgical repair is indicated when a meniscal root disinsertion occurs. However, this surgery has not yet achieved complete recovery of the joint´s natural biomechanics, with the meniscus-suture interface identified as a potentially determining factor. Knowing the deformation and resistance behavior of the sutured meniscal horn and whether these properties are preserved as the patient ages could greatly contribute to improving repair outcomes. Methods: A cadaveric experimental study was conducted on human sutured menisci classified into three n = 22 age groups (young ≤55; 55 < middle-aged ≤75; 75 < old) were subjected to load-to-failure test by suture pulling. Meniscal thickness at the suture hole was measured and the applied traction force and tissue deformation in the suture area in the direction of traction were recorded during the test. The traction load that initiated the meniscal cut-out, F c , maximum load borne by the meniscus, F u , tissue stress at the cut-out initiation, S c , and equivalent stiffness modulus at the suture area, m s , were calculated. Results: At the tissue level, the resistance in terms of S c decrease with age (young: 47.2 MPa; middle-aged: 44.7 MPa; old: 33.8 MPa) being significantly different between the young and the old group (p = 0.015). Mean meniscal thickness increased with age (young: 2.50 mm; middle-aged: 2.92 mm; old: 3.38 mm; p = 0.001). Probably due to thickening, no differences in resistance were found at the specimen level, i.e., in F c (overall mean 58.2 N) and F u (overall mean 73.6 N). As for elasticity, m s was lower in the old group than in the young group (57.5 MPa vs. 113.6 MPa, p = 0.02) and the middle-aged one (57.5 MPa vs. 108.0 MPa, p = 0.04). Conclusion: Regarding the influence of age on the sutured meniscal horn tissue, in vitro experimentation revealed that meniscal horn specimens older than 75 years old had a more elastic tissue which was less resistant to cut-out than younger menisci at the suture hole area. However, a thickening of the meniscal horns with age, which was also found, leveled out the difference in the force that initiated the tear, as well as in the maximum force borne by the meniscus in the load-to-failure test.

Comparison of medial tibiofemoral joint mechanics between all-suture anchors and transtibial pullout technique for posterior medial meniscal root tears. J Orthop Surg Res 2023; 18:591. [PMID: 37559157 PMCID: PMC10413628 DOI: 10.1186/s13018-023-04071-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 08/03/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND The posterior medial meniscal root tear (PMMRT) seriously impacts the tibiofemoral joint biomechanics. Two available techniques for PMMRT repair include the transtibial pullout (TPO) repair and all-suture anchor (ASA) repair techniques. These techniques have not been compared biomechanically. METHODS A total of 20 fresh porcine cadaveric knee specimens were used. All 20 knees were randomly and evenly distributed into four groups (five specimens per group): (1) intact posterior meniscal root, (2) PMMRT, (3) TPO repair technique for PMMRT, and (4) ASA repair technique for PMMRT. The tibiofemoral contact mechanics were investigated using a pressure sensor. All knee specimens were tested by being loaded with 600 N axial compressive force at three different flexion angles (0°, 45°, and 90°). The contact surface area, contact pressure, peak pressure, and time-zero displacement were recorded. RESULTS The PMMRT caused a significant decrease in contact surface area, an increase in contact pressure, and peak pressure from the reference values observed in the intact meniscus group (P = 0.05, 0.016, and 0.008, respectively). After fixation, no significant difference was observed between the ASA and intact group. Meanwhile, significant differences were found between the TPO and intact group in terms of contact surface area, contact pressure, and peak pressure. In the comparison between the two techniques, the ASA group demonstrated higher contact surface area than the TPO group at the average knee flexion angle (p = 0.05). CONCLUSION For most testing conditions, the ASA technique demonstrated superior biomechanical property in terms of contact surface area compared with the TPO technique under compressive loading conditions. The ASA technique could also restore the tibiofemoral contact mechanics to be comparable with those of the native intact knee. Meanwhile, a significant difference in tibiofemoral mechanics, compared with the intact knee, could be observed in the TPO technique.

Abstract
All-suture anchors (ASA) are newer anchors that anchor soft tissues to the bone. It has several biomechanical and clinical advantages; however, the high cost of this anchor limits its use in low socioeconomic countries. The cost of the anchor dramatically increases the cost of surgery; hence, acceptance of surgery is also affected if patients have to pay their expenditure from their pocket. We have designed a simple, cost-effective method of making an ASA, which can be made instantly and used during surgery; hence, the name "make-and-use anchor." To make this anchor, few high-strength sutures are required. Over the suture, a sleeve of suture was created using an Ethibond. This sleeve will create a "ball" after deployment under the cortical bone, which provides anchorage to the sutures serving as an anchor. This anchor can be deployed both in the pull-in and push-in methods. This technical note aims to share the technique of making this cost-effective anchor, which is made instantly using locally available suture materials and can be used in various surgeries requiring anchors.

Arthroscopic Triple-Loaded Soft Anchor Technique in Medial Meniscal Root Repair: A Systematic, Step-by-Step Approach. Arthrosc Tech 2022; 11:e1851-e1861.

Abstract
The results of meniscal root repair (MRR) have shown that this repair is the best treatment option in the presence of an acute situation with no degenerative changes. The meniscal root could be restored, in addition to the meniscus's hoop stress function, which is a key component in preventing osteoarthritis progression in the future. Several MRR techniques have been developed, and both improved biomechanics and a lower incidence of failure repair are correlated with suture anchor techniques. Suture anchor techniques also have many ways in which they can be adapted until the disadvantages are eliminated, such as the risk of a major neurovascular problem in the posterior compartment and the difficulty of preparing the base of the meniscal footprint because visualization in the medial compartment of the knee is limited. My MRR technique can improve knee function and allow a return to normal activities without the development of osteoarthritis by relying on the concepts of biomechanics and the regeneration process.

Abstract
ZusammenfassungEs wird der Fall einer isolierten Wurzelverletzung des Innenmeniskushinterhorns bei einer 20-jährigen Patientin nach Sprung von einem 2,5 m hohen Turm geschildert. Die Therapie bestand in der arthroskopischen Refixation der Hinterhornwurzel mittels transtibialer Auszugsnaht. Postoperativ wurde eine Teilbelastung und Begrenzung der Beugung auf 90° für 6 Wochen verordnet. Nach 4 Monaten war die Patientin wieder sportlich voll belastbar mit nur marginalen funktionellen Defiziten im Rahmen einer Return-to-sport-Testung. Eine Kontroll-Magnetresonanztomographie (MRT) zeigte eine gute Einheilung der Meniskushinterhornwurzel ohne Zeichen einer Extrusion. Isolierte traumatische Wurzelverletzungen der Menisken bei jungen Patient:innen sind selten, weisen allerdings eine gute und rasche Heilungstendenz auf, wenn diese frühzeitig erkannt und operativ adressiert werden.

Abstract
The specific meniscus injury pattern were divided into many patterns. Nowadays, the meniscus root injury, radial tear meniscus, bucket handle tear meniscus and Ramp lesion were particularly focused on many way to manage and still controversial a lot of issues. Meniscus root tears (MRTs) and Ramp lesion are the most ignored, or misdiagnosed causes of chronic knee pain. Most patients delayed seeking treatment, consequently resulting in cartilage loss, and leading to the condition progressing to osteoarthritis knee. This has resulted in the rate of MR and Ramp repair increase significantly. The bucket handle meniscus tear trend to strong saving the anatomical meniscus and avoid to menisectomy. This article, on the other hand, will reveal you how to save and secure a nearly native meniscus fixation. In case of the radial meniscus, the partial meniscectomy is still used to treat this type of injury today, but it does not prevent degenerative changes from occurring, which can lead to unfavorable outcomes. Meniscal repair is a popular procedure for treating radial tears as an alternative to surgery. However, this pattern of meniscus tear can be difficult to repair and has a high failure rate, the arthroscopic meniscus repair techniques are published.

Abstract
The meniscus is a key stabilizing tissue of the knee that facilitates proper tracking and movement of the knee joint and absorbs stresses related to physical activity. This review article describes the biology, structure, and functions of the human knee meniscus, common tears and repair approaches, and current research and development approaches using modern methods to fabricate a scaffold or tissue engineered meniscal replacement. Meniscal tears are quite common, often resulting from sports or physical training, though injury can result without specific contact during normal physical activity such as bending or squatting. Meniscal injuries often require surgical intervention to repair, restore basic functionality and relieve pain, and severe damage may warrant reconstruction using allograft transplants or commercial implant devices. Ongoing research is attempting to develop alternative scaffold and tissue engineered devices using modern fabrication techniques including three-dimensional (3D) printing which can fabricate a patient-specific meniscus replacement. An ideal meniscal substitute should have mechanical properties that are close to that of natural human meniscus, and also be easily adapted for surgical procedures and fixation. A better understanding of the organization and structure of the meniscus as well as its potential points of failure will lead to improved design approaches to generate a suitable and functional replacement.

Abstract
Radial tears increase tibiofemoral contact pressure and disrupt the ability of the meniscus to withstand hoop stress, leading to earlier-onset osteoarthritis. Repair of radial tears is problematic because they have a lower healing rate and lack a single gold standard technique. However, when a radial tear is proximal to the root, there is an opportunity to convert it into a root tear. This is ideal because root tears fixed through a transtibial tunnel technique have improved clinical outcomes and reduced rates of osteoarthritis. This Technical Note and accompanying video describe a method for repairing a radial tear near the meniscus root by converting a radial tear to a root tear followed by a pull-out root repair through a transtibial tunnel. This method restores the meniscus root, allowing it to withstand hoop stress. Our technique uses a disposable root repair kit that includes a FlipCutter, a Knee Scorpion Suture Passer, a 4.75-mm SwiveLock anchor tap, a SutureLasso, a PassPort Cannula, 0 FiberLink sutures, and TigerLink sutures.
