Objective: To report and compare the results of posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) reconstructions.
Methods: In total, 42 patients were retrospectively evaluated, 20 with isolated PCL injuries (group 1) and 22 with isolated ACL ones (group 2) who were subjected to arthroscopic ligament reconstruction with autologous grafts and followed up for at least two years. To evaluate the results in group 1, objective IKDC and Lysholm scores, posterior drawer tests, and evaluations by a KT-1000 arthrometer were used, whereas for group 2, subjective IKDC and Lysholm score and the Lachman test were employed. To compare groups, objective IKDC and Lysholm scores and assessment via a KT-1000 arthrometer were considered.
Results: Intragroup analysis showed improved results for all variables (p < 0.001) in both groups. Comparisons between groups showed a significant difference in objective IKDC scores (p < 0.001), but no such disparities for Lysholm ones (p = 0.052), clinical tests (p = 0.058) or evaluation by KT-1000 (p = 0.129).
Conclusion: Treatment restored knee stability and function in both groups. Comparisons between groups showed that PCL reconstructions had inferior results than ACL ones according to patients' objective IKDC scores.

Indications for the addition of a patellofemoral joint arthroplasty following a previous unicondylar knee arthroplasty- a literature review and Delphi consensus.
Arch Orthop Trauma Surg
January 2025
Institute for Locomotion, Aix-Marseille University, Marseille, France.
Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.
Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).
Questioning the rules of engagement: a critical analysis of the use of limb symmetry index for safe return to sport after anterior cruciate ligament reconstruction.

Sahlgrenska Sports Medicine Center, Gothenburg, Sweden.
Objective: To evaluate the association between limb symmetry index (LSI) in quadriceps and hamstrings strength together with hop tests, as a proxy of recovery, and the deviation from being symmetrical (LSI 100%), with a safe return to sport (RTS) after anterior cruciate ligament reconstruction (ACL-R).
Methods: Athletes between 15 and 30 years old with a preinjury Tegner activity level ≥6 were eligible for inclusion. Data were extracted from a rehabilitation-specific registry, Project ACL (Gothenburg, Sweden) at the time of or after RTS for each athlete.
Comparative Evaluation of Treatment Outcomes of Revision Anterior Cruciate Ligament Reconstruction Using Allograft and Semitendinosus Autograft.

Department of Orthopedics, Traumatology and Hand Surgery, Faculty of Medicine, Wroclaw Medical University, 50-556 Wroclaw, Poland.
The number of revision anterior cruciate ligament reconstruction (RACLR) procedures is increasing in proportion to the increase in the number of anterior cruciate ligament reconstruction (ACLR) procedures. Although approximately 50-75% of these procedures can be performed in a single-stage procedure, not all of them can. The choice of graft may influence the results of RACLR.

Anterior cruciate ligament (ACL) injuries are common in athletes, but their prevalence has also increased among adults. ACL reconstruction (ACLR) is a key treatment option, with graft choice playing a critical role in recovery. The study evaluates the clinical and functional outcomes of ACLR using the Ligament Augmentation and Reconstruction System (LARS) in patients over 35 years old.

Rupture of the anterior cruciate ligament (ACL) is common among soccer players. Although there are no strict recommendations for the return to sport, more and more practitioners are having their patients perform isokinetic and even composite tests. However, these tests have not yet been shown to be predictive of re-injury, and are not specific to professional footballers.
