    Combined Reconstruction of the Anterolateral Ligament in Patients With Anterior Cruciate Ligament Injury and Ligamentous Hyperlaxity Leads to Better Clinical Stability and a Lower Failure Rate Than Isolated Anterior Cruciate Ligament Reconstruction
    (2019) HELITO, Camilo Partezani; SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; DEMANGE, Marco Kawamura
    Purpose: To compare functional outcomes, residual instability, and rupture rates in patients with ligamentous hyperlaxity undergoing isolated anterior cruciate ligament (ACL) reconstruction or combined ACL and anterolateral ligament (ALL) reconstruction. Methods: Two groups of patients were evaluated and compared retrospectively. Both groups consisted of patients with ACL injuries and associated ligamentous hyperlaxity, defined based on the modified Beighton scale with a minimum score of 5. Group 1 patients underwent anatomical ACL reconstruction, and group 2 patients underwent anatomical ACL reconstruction combined with ALL reconstruction. Group 1 consisted of historical controls. The presence of associated meniscal injury, subjective International Knee Documentation Committee and Lysholm functional scores, KT-1000 measurements, the presence of a residual pivot-shift, and the graft rupture rate were evaluated. The study was performed at University of Sao Paulo in Brazil. Results: Ninety patients undergoing ACL reconstruction with ligamentous hyperlaxity were evaluated. The mean follow up was 29.6 +/- 6.2 months for group 1 and 28.1 +/- 4.2 months for group 2 (P = .51). No significant differences were found between the groups regarding Beighton scale, gender, the duration of injury before reconstruction, follow-up time, preoperative instability, or associated meniscal injuries. The mean age was 29.9 +/- 8.1 years in group 1 and 27.0 +/- 9.1 years in group 2 (P = .017). In the final evaluation, group 2 patients showed better anteroposterior clinical stability as evaluated by KT-1000 arthrometry (P = .02), better rotational stability as evaluated by the pivot-shift test (P = .03) and a lower reconstruction failure rate (21.7% [group 1] vs 3.3% [group 2]; P = .03). Clinical evaluations of postoperative functional scales showed no differences between the 2 groups (P = .27 for International Knee Documentation Committee; P = .41 for Lysholm). Conclusions: Combined ACL and ALL reconstruction in patients with ligamentous hyperlaxity resulted in a lower failure rate and improved knee stability parameters compared to isolated ACL reconstruction. No differences were found in the functional scales.

    Surgical Timing Does Not Interfere on Clinical Outcomes in Combined Reconstruction of the Anterior Cruciate Ligament and Anterolateral Ligament: A Comparative Study With Minimum 2-Year Follow-Up
    (2021) HELITO, Camilo Partezani; SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; GOBBI, Riccardo Gomes; CAMANHO, Gilberto Luis
    Purpose: To compare the functional outcomes, knee stability, failure rate and complication rates of combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction with hamstrings grafts between acute and chronic cases. Methods: Consecutive patients who underwent combined ACL and ALL reconstruction with hamstrings grafts were evaluated. Patients operated on less than 8 weeks after injury were allocated to group 1, and the others were allocated to group 2. Demographic data, knee stability, and functional outcomes of the 2 groups were evaluated. Results: Thirty-four patients in the acute group and 96 in the chronic group were evaluated. The follow-up time was similar between the groups (28.7 +/- 5.2 [24-43] months vs 29.4 +/- 7.2 [24-58] months; P = 0.696). No differences were found between the groups in age, sex, trauma mechanism, presence of knee hyperextension, graft diameter, and meniscal injuries. There was no difference between the groups in the postoperative KT-1000 and in the pre- or postoperative pivot shift. The preoperative KT-1000 was higher in group 2 (7.9 +/- 1.1 vs 7.4 +/- 1.2; P = 0.031). There were no differences in the International Knee Documentation Committee or Lysholm. Three (2.3%) patients developed failure, 1 (2.9%) in group 1 and 2 (2.1%) in group 2. The total complication rate was 10% and did not differ between the groups. Conclusions: Combined ACL and ALL reconstruction has similar outcomes in patients undergoing surgery in the acute and chronic phases. Patients with chronic injury have similar knee stability, functional scores, and failure rates as acute-injury patients, and patients with acute injury have no more complications than chronic patients. Level of Evidence: Level III, retrospective comparative therapeutic trial.

    Degenerative Medial Meniscus Tear With a Displaced Flap Into the Meniscotibial Recess and Tibial Peripheral Reactive Bone Edema Presents Good Results With Arthroscopic Surgical Treatment
    (2021) HELITO, Camilo Partezani; HELITO, Paulo Victor Partezani; SOBRADO, Marcel Faraco; GIGLIO, Pedro Nogueira; GUIMARAES, Tales Mollica; PECORA, Jose Ricardo; GOBBI, Riccardo Gomes; RODRIGUES, Marcelo Bordalo; BERG, Bruno Vande
    Purpose: To report the arthroscopic treatment results of a degenerative medial meniscus tear with a displaced flap into the meniscotibial recess, tibial peripheral reactive bone edema, and focal knee medial pain. As a secondary objective, we propose to identify possible factors associated with a good or poor prognosis of the surgical treatment of this lesion. Methods: From 2012 to 2018, patients who had this specific meniscus pathology and underwent arthroscopic surgical treatment were retrospectively evaluated. Patients with Kellgren-Lawrence (KL) classification greater than 2 were excluded. KL classification, the presence of an Outerbridge grade III/V chondral lesion of the medial compartment, limb alignment, body mass index, and smoking were evaluated. The subjective outcomes included the International Knee Documentation Committee score, improvement in the pain reported by patients, and the Global Perceived Effect (GPE) scale score. Results: A total of 69 patients were evaluated. The mean age was 58.6 +/- 7.1 years. The follow-up time was 48.7 +/- 20.8 months. Fifty-five (79.7%) patients reported pain improvement. The postoperative International Knee Documentation Committee was 62.6 +/- 15.4, and the mean GPE was 2.3 +/- 2.6. Fourteen patients (20.3%) showed no improvement in pain, and 7 patients (10.2%) presented complications. Groups that improved (GPE 0) and did not improve (GPE < 0) did not present differences regarding age, sex, follow-up time, chondral lesions, or body mass index. Patients without improvement had a greater incidence of smoking (P = .001), varus alignment (P = .008), and more advanced KL classification (P < .001). In the multivariate analysis based on the GPE score, KL classification (P = .038) and smoking (P = .003) were significant. Conclusions: Arthroscopic surgical treatment of degenerative medial meniscal tears with a meniscal flap displaced into the meniscotibial recess and adjacent focal bone edema in the tibia shows good results in approximately 80% of cases. Smoking and KL grade 2 were factors associated with poor prognosis of surgical treatment.

    Patellar Tilt and Patellar Tendon-Trochlear Groove Angle Present the Optimum Magnetic Resonance Imaging Diagnostic Reliability for Patients With Patellar Instability
    (2023) GOBBI, Riccardo Gomes; CAVALHEIRO, Camila Maftoum; GIGLIO, Pedro Nogueira; HINCKEL, Betina Bremer; CAMANHO, Gilberto Luis
    Purpose: To describe, in controls and in a population with patellar instability, magnetic resonance imaging values of measurements representing major associated factors for patellar instability (patellar height, trochlear dysplasia, and extensor mechanism alignment), as well as their cutoff values. Methods: In total, 323 knee magnetic resonance imaging scans, 142 with patellar instability and 181 controls without patellofemoral complaints (anterior cruciate, medial collateral ligament, meniscus ruptures or normal) were evaluated. Means, normality values in the control population, ideal cutoff values through receiver operating characteristic curves analysis, and interobserver reliability (intraclass correlation coefficient) were described for a series of measurements. Results: All measurements were statistically different in control and instability patients, except for the patellotrochlear index and tibial tuberosity to posterior cruciate ligament distance. The interobserver intraclass correlation coefficient was good or excellent (above 0.75) only for the patellotrochlear index, patellar tendon-trochlear groove (PTTG) angle, and patellar tilt. The optimal cutoff value for each measurement was: PTTG angle >= 25.3(degrees) with sensitivity (S) of 70% and specificity (E) of 89%, patellar tilt >= 16o (S: 69% and E: 84%), trochlear sulcus angle >= 153(degrees) (S: 75% and E: 76%), Carrillon <= 12.8(degrees) (S: 62% and E: 87%), PTTG distance >= 11mm (S: 71% and E: 78%), Caton-Deschamps index >= 1.23 (S: 72% and E: 76%) and trochlear bump >= 3.95 mm (S: 76% and E: 65%). Conclusions: Caton-Deschamps index (>= 1.23), trochlear sulcus angle (>= 153(degrees)), ventral prominence of the trochlea (>= 3.95 mm), PTTG distance (>= 11 mm), PTTG angle (>= 25.3o), Carrillon angle (<= 12.8(degrees)), and patellar tilt (>= 16(degrees)) presented better diagnostic performance for patellar instability. Patellotrochlear index and tibial tuberosity to posterior cruciate ligament distance were not related to patellar instability. The interobserver reliability of the factors related to patellar instability was excellent only for the PTTG angle and lateral patellar tilt. Level of Evidence: Level III, retrospective case-control study.
