“…In the examined group of patients, 15% demonstrated knee instability exceeding 3 mm compared to the uninvolved limb. It is a quantity denoting ligament insufficiency as described by the authors [13,22,23]. Bach et al described the results of patellar tendon autografts 2 years after the procedure, and showed that 5% of patients had a difference of more than 3 mm between their knees [24].…”

Introduction: ACL damage results in instability of the knee joint. It is characterized by abnormal hypermobility leading to repeated injuries of the joint. Aim of the research:To evaluate the function of the knee joint in relation to mechanical stability and to evaluate the parameters influencing the stability of the knee joint in the period of 3 to 5 years after surgery. Material and methods:The study enrolled 51 patients, 38 men and 13 women, operated on due to ACL rupture. The knee joint stability was assessed with a Rolimeter and the Lysholm scale, and the isokinetic muscle strength was measured with a Biodex 4 dynamometer. The study was carried out in the period from 3 to 5 years after the operation. Results: The difference between the Rolimeter measurement of the uninvolved knee and operated one was no more than 3 mm in most of the respondents (84.3%). Joint instability over 3 mm was observed in 15.7% of the respondents. The strength of the extensor muscles of the knee joint was significantly higher in the uninvolved limbs compared to the operated ones. Conclusions: After ACL reconstruction, some patients have instability in the operated joint. Assessment of the function and instability of the knee joint using the subjective Lysholm scale is comparable to the assessment performed with the objective research tool -the Rolimeter. Patients after arthroscopic ACL reconstruction develop chronic muscle strength disorders. StreszczenieWprowadzenie: Następstwem uszkodzenia ACL jest niestabilność stawu kolanowego. Charakteryzuje się ona nieprawidłową, nadmierną ruchomością, która prowadzi do ponownych urazów stawu. Cel pracy: Ocena funkcji stawu kolanowego w odniesieniu do stabilności mechanicznej oraz ocena parametrów wpływających na stabilność stawu kolanowego w okresie od 3 do 5 lat od operacji. Materiał i metody: Materiał badań stanowiło 51 pacjentów, 38 mężczyzn i 13 kobiet, operowanych z powodu zerwania ACL. Średnia wieku badanych to 34,4 ±7,2 roku. Przeprowadzono ocenę stabilności stawu kolanowego za pomocą rolimetra, ocenę funkcjonalną za pomocą skali Lysholma oraz badanie izokinetyczne siły mięśni prostowników i zginaczy stawu kolanowego za pomocą dynamometru Biodex 4 pro. Badanie przeprowadzono w okresie od 3 do 5 lat od operacji. Wyniki: U większości badanych (84,3%) różnica pomiędzy pomiarem rolimetrem kolana zdrowego i operowanego wyniosła nie więcej niż 3 mm. Niestabilność stawu powyżej 3 mm zaobserwowano u 15,7% badanych. Siła mięśni prostowników stawu kolanowego jest znacząco wyższa w kończynach zdrowych w porównaniu z kończynami operowanymi. Wnioski: Po zabiegu rekonstrukcji ACL u części pacjentów nadal stwierdza się niestabilność operowanego stawu. Ocena funkcji oraz niestabilności stawu kolanowego subiektywną skalą Lysholma jest porównywalna z oceną wykonaną obiektywnym narzędziem badawczym -rolimetrem. U pacjentów po artroskopowej rekonstrukcji ACL występują przewlekłe zaburzenia siły mięśniowej.

“…Similarly, an objective assessment of anterior laxity was performed by measuring ATT with Rolimeter. Rolimeter measurements are a reliable method for measuring anterior knee laxity, including in the acute phase of knee injuries [ 16 ]. Median ATT was found to be decreased significantly from 10 mm preoperatively to 2 mm at one month (p<.05), remained the same at six months, and rose to 3 mm at the 12-month follow-up (p>.05).…”

Background and objectiveThe primary goal of anterior cruciate ligament reconstruction (ACLR) is to protect the initial graft fixation against heavy loads encountered during the rehabilitation phase. The purpose of this study was to evaluate the functional outcomes (Lysholm score) and laxity [anterior tibial translation (ATT), anterior drawer test, Lachman test, and pivot shift test] of ACLR with adjustable-loop femoral cortical suspensory fixation (CSF) and tibial interferences crew fixation. MethodsThis study included 100 patients who underwent primary ACL reconstruction using quadruple hamstring grafts secured with TightRope® (Arthrex Inc, Naples, FL) femoral fixation and an interference screw on the tibial end. Six patients were excluded from the final analysis (four lost to follow-up, one suffered re-injury, and one had septic arthritis). The remaining 94 patients were evaluated for laxity and functional outcomes preoperatively, as well as at one, six, and 12 months postoperatively. Regression analysis was performed to determine the association between outcomes and 11 independent variables. This was designed as a prospective cohort study (level of evidence: II). ResultsThe mean age of the participants was 28.46 ± 7.01 years. The median preoperative Lysholm knee score of 49 (mean ± SD: 48.2 ± 5.42) improved to 93 (92.7 ± 2.1) at six months and 98 (97.6 ± 2.1) at the one-year followup. The improvement was found to be statistically significant (p<0.01). The median ATT was 10 mm preoperatively, which decreased to 2 mm at one month, remained the same at six months, and rose to 3 mm at the one-year follow-up. ATT was found significantly reduced at one month postoperatively (p<.001) and did not show any significant further changes at subsequent follow-ups (p>0.05). Multiple linear regression revealed that one-year postoperative ATT (Rolimeter, Aircast Europa, Stephanskirchen, Germany) was independent of all demographic and perioperative variables tested. ConclusionQuadrupled hamstring graft ACLR with adjustable-loop fixation showed excellent subjective and objective outcomes with no residual laxity or failure of graft over mid-term follow-up. Postoperative laxity was not correlated with graft and tunnel dimensions.

Background: We developed a quadriceps-tendon graft technique using a double-layered, partial-thickness, soft tissue quadriceps tendon graft (dlQUAD) for anterior cruciate ligament reconstruction (ACLR). This technique allows simple femoral loop button fixation and a limited harvest depth of the quadriceps tendon. Purpose: To evaluate the outcome of patients undergoing revision ACLR using the dlQUAD technique compared with a hamstring tendon graft (HT). Study Design: Cohort study; Level of evidence, 3. Methods: A total of 114 patients who underwent revision ACLR between 2017 and 2018 were included in this retrospective case series. At a mean follow-up of 26.9 ± 3.7 months (range, 24-36), 89 patients (dlQUAD: n = 43, HT: n = 46) were clinically examined. In addition, patients completed the Lysholm score, Tegner activity scale, subjective International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score, and visual analog scale (VAS) for pain. Postoperative failure of the revision ACLR was defined as a side-to-side difference (SSD) in Rolimeter testing ≥5 mm or a pivot-shift grade of 2 or 3. Results: Nine patients (10.1%) were identified with a failed revision ACLR. There was a significantly lower failure rate with dlQUAD versus the HT group (2.3% vs 17.4%; P = .031). The mean postoperative SSD was significantly less in the dlQUAD group (1.3 ± 1.3 mm [range, 0-5] vs 1.8 ± 2.2 mm [range, 0-9]; P = .043). At the latest follow-up, Tegner and IKDC scores significantly improved in the dlQUAD group compared with the HT group (Tegner: 5.8 ± 1.8 vs 5.6 ± 1.5; P = .043; IKDC: 83.8 ± 12.2 vs 78.6 ± 16.8; P = .037). The pain VAS score was also significantly reduced in the dlQUAD group compared with the HT group (0.9 ± 1.1 vs 1.6 ± 2.0; P = .014). Conclusion: The dlQUAD and HT techniques both demonstrated significant improvement of preoperative knee laxity and satisfactory patient-reported outcome measures after revision ACLR. Compared with the HT grafts, the dlQUAD technique showed lower failure rates and small increases in Tegner and IKDC scores.
