Arthroscopic and open reconstruction of the posterolateral corner of the knee have equally good clinical results: first results of a prospective 12-month follow-up study. Arch Orthop Trauma Surg 2024; 144:2745-2752. [PMID: 38795185 PMCID: PMC11211137 DOI: 10.1007/s00402-024-05355-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 04/28/2024] [Indexed: 05/27/2024]
Abstract
PURPOSE Arthroscopic reconstruction techniques for higher-grade posterolateral corner (PLC) injuries (Fanelli Type B, PoLIS LI-B) have not yet been validated in clinical studies. The open reconstruction technique described by Arciero is well-established and showed good restoration of joint stability in previous studies. This study aimed to compare clinical outcomes of this established open surgery technique to a newly developed arthroscopic technique in a prospective randomized clinical trial. METHODS Between 2019 and 2021, this study focused on chronic high-grade PLC injuries (Fanelli Type B, PoLIS LI-B). Group A consisted of patients treated with conventional open surgery following Arciero's technique, while Group B included patients treated with Arciero's arthroscopic technique. All cases underwent additional PCL reconstruction. After a minimum 12-month follow-up, clinical scores and objective stability assessments were compared between the groups. RESULTS In total, 26 (group A 12, group B 14) eligible patients with a mean follow-up of 14.9 ± 7.2 months were evaluated in the present study. Knee stability and patient-reported outcome scores (PROMS) were significantly improved when comparing pre- and post-operative values (p < 0.0001). No clinically relevant differences in PROMS (Lysholm: A 83.9 ± 11.4 vs. B 85.3 ± 13.8; IKDC: A 76.91 ± 12.6 vs. B 76.8 ± 15.7) were shown in both groups. Additionally, no statistically significant differences were detected between groups with respect to external rotation, range of motion and instrumental stability testing. Arthroscopic reconstruction showed significantly shorter operation time (p = 0.0109). There were no clinical failures or neurovascular complications of the surgical procedures. CONCLUSION Both surgical techniques for isolated chronic PLC Fanelli Type B injuries significantly improved the knee stability, were equivalent with respect to PROMs and led to good clinical results. However, arthroscopic PLC reconstruction was associated with a shorter surgery time compared to open PLC reconstruction. Therefore, arthroscopic PLC reconstruction may be a viable option in the hands of an experienced surgeon. LEVEL OF EVIDENCE Prospective cohort study, II.

Abstract
PURPOSE To evaluate and analyze the current literature regarding clinical outcomes after posterolateral corner reconstruction (PLCR) using fibular-based and tibial-based techniques. METHODS A systematic review of the literature was performed to evaluate patient-reported outcomes after PLCR. Embase, PubMed, and Scopus were searched from their respective inception through October 25, 2022. Studies containing patient-reported outcome scores of tibial and fibular-based PLCR were included. Outcomes collected from each study were summarized using t tests for consistently reported Tegner, Lysholm, and International Knee Documentation Committee Score. RESULTS Twenty-four studies (16 with level of evidence IV, 6 with Level III, and 2 with Level II) met the inclusion criteria and included 669 patients in total. Four studies comprising 111 patients directly compared the results of tibial- and fibular-based PLCR. Mean clinical follow-up across all studies was 3.3 years. The 4 studies that reported on both tibial and fibular-based PLCR were found to have no significant differences in patient-reported outcomes with P values ranging from .0561 to .9881. CONCLUSIONS Analysis of the available literature regarding tibial- and fibular-based posterolateral corner reconstruction suggests no clinical differences. LEVEL OF EVIDENCE Level II-IV, review of systematic studies.

Abstract
The posterolateral corner of the knee is composed of a multilayered complex of ligamentous, musculotendinous, and capsular structures, which interact in a synergistic stabilizing manner with the central structures, particularly the posterior cruciate ligament. Injuries of the posterolateral corner are generally accompanied by rupture of the posterior cruciate ligament. Depending on the injured structures, injuries of the posterolateral corner result in posterolateral rotational instability alone (Fanelli A) or with lateral instability (Fanelli B/C). For rotational instability alone, isolated popliteus bypass is an effective procedure; with concomitant lateral instability in flexion, additional stabilization of the lateral collateral ligament is required. Most of the various available techniques are described as open reconstruction procedures. In recent years, arthroscopic techniques for posterolateral reconstruction have also been successfully developed.

Most Publications Regarding Arthroscopic Treatment of Posterolateral Corner Injuries of the Knee Have a Low Level of Evidence and Provide Limited Information to Determine the Most Effective Treatment. Arthrosc Sports Med Rehabil 2024; 6:100904. [PMID: 38379595 PMCID: PMC10878847 DOI: 10.1016/j.asmr.2024.100904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 01/13/2024] [Indexed: 02/22/2024] Open
Abstract
Purpose To examine the Level of Evidence and overall quality of studies addressing arthroscopic posterolateral corner reconstructions of the knee. Methods A search was performed using the PubMed/Medline, Web of Science, and Google Scholar databases for all studies investigating arthroscopic treatment of posterolateral corner injuries of the knee. Studies reporting outcomes or describing arthroscopic techniques for treatment of posterolateral corner injuries of the knee were the focus of this analysis. Clinical as well as biomechanical and cadaveric studies were included. Studies only investigating open techniques were excluded. Two independent reviewers determined the level of evidence for each included study using the criteria established by the Journal of Bone and Joint Surgery and scored each clinical study from 0 to 100 based on 10 criteria from the modified Coleman Methodology Score. Results Twenty-four studies matched the inclusion criteria. There were 6 cadaveric technique descriptions, 6 clinical technique descriptions, 3 biomechanical studies, 4 technical repair descriptions, and 5 clinical outcome studies. Thirty-eight percent of all studies were of Level V evidence. Fifty percent of studies were of Level IV evidence, and 12% of studies were of Level III evidence. The mean modified Coleman Methodology Score for the clinical studies was 43 ± 11.4, which is regarded as poor, mainly due to the limited number of patients and the retrospective nature of the studies. Conclusions Most studies addressing arthroscopic posterolateral corner reconstruction of the knee are of low level of evidence and provide limited information about the best treatment options. Clinical Relevance The number of publications on arthroscopic posterolateral corner reconstruction techniques continues to rise. This systematic review evaluates the level of evidence of these studies.

Abstract
PURPOSE There remains controversy regarding the optimal surgical treatment for acute complete (grade III) posterolateral corner (PLC) injuries. The purpose of this article is to systematically review the contemporary literature regarding surgical options and subsequent outcomes of acute grade III PLC injuries. METHODS A systematic review was performed using the following search terms: posterolateral corner knee, posterolateral knee, posterolateral instability, multi-ligament knee, and knee dislocation. Inclusion criteria consisted of studies with level I-IV evidence, reporting on human patients with acute grade III PLC injuries undergoing operative management within 4 weeks from injury, with subjective and/or objective outcomes (including varus stress examinations or varus stress radiographs) reported at a minimum 2-year follow-up. Two investigators independently performed the search by sequentially screening articles. Accepted definitions of varus stability on examination or stress radiographs and revision surgery were used to determine success and failure of treatment. RESULTS A total of 12 studies, consisting of 288 patients were included. Ten studies reported primary repair, while reconstruction techniques were reported in seven studies. Overall, 43% (n = 125/288) of injuries involved the PLC, ACL and PCL. Staged reconstruction was reported in 25% (n = 3/12) of studies. The Lysholm score was the most commonly reported outcome measure. An overall failure rate of 12.4% (n = 35/282) was observed. Surgical failure was significantly higher in patients undergoing repair (21.9%; n = 21/96) compared to reconstruction (7.1%; n = 6/84) (p = 0.0058). Return to sport was greater in patients undergoing reconstruction (100%; n = 22/22) compared to repair (94%; n = 48/51) (n.s). The most common post-operative complication was arthrofibrosis requiring manipulation under anesthesia (8.7%; n = 25/288). A total of 3.8% (n = 11/288) of patients underwent revision PLC reconstruction. CONCLUSION There remains substantial heterogeneity in the surgical techniques of acute, grade III PLC injuries with an overall failure rate of 12.4%. Failure rates were significantly lower, and return to sport rates higher in patients undergoing PLC reconstruction compared to repair. The most common postoperative complication was arthrofibrosis requiring manipulation under anesthesia. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Fibular- and tibiofibular-based reconstructions are the gold standard treatment for posterolateral corner (PLC) injuries of the knee. Despite comparable outcomes in biomechanical studies, clinical results comparing these constructs remain elusive with no consensus reached regarding the best treatment option. PURPOSE To perform a systematic review and meta-analysis to compare fibular- and tibiofibular-based techniques for posterolateral corner reconstruction. We aimed to identify whether any differences existed between the 2 techniques in terms of clinical outcomes and rotational and varus stability. STUDY DESIGN Meta-analysis; Level of evidence, 4. METHODS The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms ("posterolateral corner" OR "fibular collateral ligament" OR "lateral collateral ligament" OR "popliteus tendon" OR "popliteofibular ligament") AND ("reconstruction" OR "LaPrade" OR "Larson" OR "Arciero"). Data pertaining to all patient-reported outcome measures (PROMs), postoperative complications, and valgus and rotational stability were extracted from each study. The pooled outcome data were analyzed by random- and fixed-effects models. RESULTS After abstract and full-text screening, 6 clinical studies were included. In total, there were 183 patients, of which 90 received fibular-based and 93 tibiofibular-based reconstruction. The majority of studies used similar surgical techniques regarding tunnel orientation, attachment sites, and graft fixation sequence. There were no differences between the groups in terms of PROMs and subjective knee scores at a mean of 20.3 months. The techniques were equally effective in restoring varus and rotational stability. Subgroup analysis revealed that the stability of a posterior cruciate ligament reconstruction postoperatively was not affected by either construct. CONCLUSION Both constructs had comparable clinical outcomes and were equally effective in restoring varus and rotational stability for PLC knee injuries. The fibular-based technique may offer advantages in view of being less technically demanding and invasive and requiring fewer grafts with a quicker operative time. However, higher quality studies are required to reinforce or refute such conclusions, as the majority of studies in this review were poor to fair quality.

Abstract
PURPOSE We aimed to assess the clinical and radiological outcomes of a modified anatomical posterolateral corner (PLC) reconstruction technique using a single autograft. METHODS This prospective case series included 19 patients with a posterolateral corner injury. The posterolateral corner was reconstructed using a modified anatomical technique that utilized adjustable suspensory fixation on the tibial side. Patients were evaluated subjectively using the international knee documentation form (IKDC), Lysholm, and Tegner activity scales and objectively by measuring the tibial external rotation angle, knee hyperextension, and lateral joint line opening on stress varus radiographs before and after surgery. The patients were followed-up for a minimum of 2 years. RESULTS Both IKDC and Lysholm knee scores significantly improved from 49 and 53 preoperatively to 77 and 81 postoperatively, respectively. The tibial external rotation angle and knee hyperextension showed significant reduction to normal values at the final follow-up. However, the lateral joint line opening measured on the varus stress radiograph remained larger than the contralateral normal knee. CONCLUSION Posterolateral corner reconstruction with a hamstring autograft using a modified anatomical reconstruction technique significantly improved both the subjective patient scores and objective knee stability. However, the varus stability was not completely restored compared with the uninjured knee. LEVEL OF EVIDENCE Prospective case series (Level of evidence IV).
