Purpose: The purpose of this study was to evaluate the functional and radiographic results on a midterm basis, as well as complications, in an initial series of meniscal allograft transplantations performed with suture fixation without any bone block.
Methods: A series of 33 meniscal allograft transplantations were performed at our institution from January 2001 to October 2003. Inclusion criteria were patients with compartmental joint line pain due to a previous meniscectomy. There were 24 men and 9 women with a mean age of 38.8 years (range, 21 to 54 years). The functional outcomes were evaluated by use of Lysholm and Tegner scores at a mean and minimum follow-up of 6.5 years and 5 years, respectively. A visual analog scale for pain was also used. Radiographic assessment included joint space narrowing on the Rosenberg view and magnetic resonance imaging evaluation.
Results: The Lysholm and Tegner scores significantly improved from 65.4 to 88.6 (P < .001) and from 3.1 to 5.5 (P < .001), respectively, after surgery. The visual analog scale score significantly dropped from 6.4 to 1.5 (P < .001). The radiographic evaluation did not show any joint space narrowing (P = .38). Meniscal extrusion was a constant finding, averaging 36.3% of total meniscal size. According to the Van Arkel criteria, the survival rate was 87.8% at 6.5 years. The rate of complications was 33%.
Conclusions: This study suggests that this procedure provides significant pain relief and functional improvement in selected symptomatic individuals on a midterm basis. However, there was a high rate of complications (33%) and revision surgery.
Level Of Evidence: Level IV, therapeutic case series.

Clinical and Radiological Outcomes After Lateral Meniscal Allograft Transplantation Through a Medial Arthrotomy: A Minimum 4-Year Follow-up.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Case Western Reserve University, Cleveland, Ohio, USA.
Background: Previous studies have demonstrated that lateral meniscal allograft transplantation (MAT) through medial arthrotomy showed less extrusion than that of the lateral arthrotomy. However, there is a paucity of literature reporting clinical and radiological outcomes after lateral MAT through the medial arthrotomy.
Hypothesis: Lateral MAT through a medial arthrotomy would show significantly improved clinical scores and minimal joint space narrowing compared with preoperative status.
Interposition Arthroplasty with Meniscal Allograft for the Treatment of Sternoclavicular Joint Pathology; The SC Calamari Technique.

Background: Painful degeneration of the sternoclavicular joint refractory to nonoperative treatment has historically been managed with resection of the degenerative segment of the medial clavicle. Although this has produced good results with improvement in symptoms, recurrent pain necessitating revision surgery is not an infrequently encountered outcome. To reduce the occurrence of recurrent postoperative pain, a novel technique to reconstruct the intra-articular disc at the time of medial clavicle resection was developed.

- Meniscal extrusion (ME) is a significant predictor of knee joint degeneration, but existing classifications primarily use numerical assessments without considering the underlying causes of ME.
- Evidence suggests that ME can arise from various conditions, including acute tears, chronic degeneration, and even joint loading or anatomical issues that are not necessarily indicative of pathology.
- A new qualitative classification is proposed to categorize ME into paraphysiological, pathological, and degenerative types, with an emphasis on adapting clinical management based on these distinct categories.
Return to Sport After ACL Reconstruction With Meniscal Allograft Transplantation Versus Isolated ACL Reconstruction: A Matched-Cohort Study.
Am J Sports Med
January 2025
Memorial Hermann Rockets Sports Medicine Institute, Department of Sports Medicine & Rehabilitation, Houston, Texas, USA.
Background: Meniscal allograft transplantation (MAT) is indicated in the setting of anterior cruciate ligament (ACL) reconstruction to restore proper arthrokinematics and load distribution for the meniscus-deficient knee. Objective outcomes after ACL reconstruction with concomitant MAT in athletic populations are scarcely reported and highly variable.
Purpose: To compare patient outcomes using an objective functional performance battery, self-reported outcome measures, and return-to-sport rates between individuals undergoing ACL reconstruction with concomitant MAT and a matched group undergoing isolated ACL reconstruction.

Purpose: To compare graft remodeling, as measured by magnetic resonance imaging (MRI), and clinical outcomes between patients who underwent isolated anterior cruciate ligament reconstruction (ACLR) versus combined anterior cruciate ligament and anterolateral ligament reconstruction (ACLR + ALLR).
Methods: A retrospective review was conducted on patients who underwent primary ACLR with quadruple hamstring grafts between January 2019 and March 2022, with a minimum follow-up period of 2 years. Patients were categorized into 2 groups on the basis of the addition of ALLR with tibialis anterior allografts: an isolated ACLR group and an ACLR + ALLR group.
