Is There Any Relationship Between Preoperative and Early Postoperative Maximal Isometric Strength in Patients Who Underwent ACL Reconstruction With Patellar Tendon?

Is There Any Relationship Between Preoperative and Early Postoperative Maximal Isometric Strength in Patients Who Underwent ACL Reconstruction With Patellar Tendon? J Sport Rehabil. 2019 May 16;:1-19 Authors: Mariani PP, Laudani L, Rocchi J, Giombini A, Macaluso A Abstract CONTEXT: All rehabilitative programs before ACL reconstructive surgery, which are focused on recovery of proprioception and muscular strength, are defined as prehabilitation. While it has shown that prehabilitation positively affects the overall outcome after ACL reconstruction, it is still controversial whether enhancing preoperatively quadriceps strength has some beneficial effect on postoperative strength, mainly during the first period. OBJECTIVE: To determine whether there is any relationship between pre- and early postoperative quadriceps strength. DESIGN: Case control. SETTING: University research laboratory. PARTICIPANTS: Fifty-nine males (18-33 y; age: 23.69 (0.71) y) who underwent ACL reconstruction with patellar-tendon autograft were examined the day before surgery, at 60 and at 90 days after surgery. MAIN OUTCOME MEASURES: The limb-symmetry-index (LSI) was quantified for maximal voluntary isometric contraction (MVIC) of the knee extensor muscles and of the knee flexor muscles at 90° joint angle. K-means analysis was performed on either quadriceps or hamstrings LSI before surgery to classify the patients in high and low preoperative LSI clusters. Diffe...

AbstractPurposeTo present the clinical outcomes and magnetic resonance imaging (MRI) analysis of adjustable cortical suspensory fixation for the femur and tibia in hamstring autograft anterior cruciate ligament reconstruction.MethodsA cohort of 233 sequential patients was analysed for graft failure rate and subjective IKDC, Tegner and Lysholm scores. 144 validated 1-year MRIs assessed and correlated graft healing and tunnel widening.ResultsAt mean follow-up of 28  months ± 8.2 [median 26, range 12–49], the graft failure rate was 4.7%. Significant improvements were seen in all clinical scores (p

Abstract Anterior cruciate ligament (ACL) tears is a devastating injury and one of the most common knee injuries experienced by athletes in the United States. Although patients reach maximal subjective improvement by one-year following ACL reconstruction, many patients often experience moderate to severe post-operative pain. Opioids, intra-articular injections, and regional anesthesia have been previously implemented to mediate post-operative pain. However, chronic opioid usage has become an epidemic in the United States. Alternative analgesic modalities, such as nerve blocks, have been implemented in clinical pra...

ConclusionChronicity of ACL injury with repeated strains can cause fibrosis at the musculotendinous junction and result in harvest of a poor quality and short hamstring autograft. A detailed history with regard to duration of injury and repeated instability episodes will help a surgeon plan better when anticipating a sub-optimal graft.

We describe safe, reproducible anatomic reconstruction of the patellar tendon using hamstring tendon and adjustable suspensory fixation. After harvesting of the hamstrings, the graft is prepared with 2 adjustable suspensory fixation devices. Then, a complete tibial tunnel and a patellar tunnel with a socket are drilled with the appropriate diameter, and the graft is pulled through the tunnels. Finally, the suspensory fixation devices on the tibial and patellar sides are tensioned. The aim of this procedure is to obtain complete mobility of the knee, using a procedure similar to anterior cruciate ligament reconstruction in graft preparation.

Unsatisfactory long-term results with synthetic grafts for anterior crucial ligament (ACL) reconstruction led knee surgeons to switch to more stable, better compatible and longer lasting autografts [1]. As urogynecologists nowadays are confronted with similar challenges regarding synthetic meshes, intellectual cross-fertilization between orthopedics and gynecologists could help solving these problems. Because native tissue repair is less effective in apical prolapse surgery, currently used repairing techniques for pelvic organ prolapse in Europe mostly employ synthetic meshes [2].

AbstractRevision anterior cruciate ligament reconstruction remains a challenge, especially optimising outcome for patients with a compromised knee where previous autogenous tissue has been used for reconstruction. Allograft tissue has become a recognized choice of graft for revision surgery but questions remain over the risks and benefits of such an option. Allograft tendons are a safe and effective option for revision ACL reconstruction with no higher risk of infection and equivalent failure rates compared to autografts provided that the tissue is not irradiated, or any irradiation is minimal. Best scenarios for use of al...

CONCLUSION: Adolescent male ACLR patients with BTB and HS autografts demonstrated significant deficits in quadriceps and hamstring strength, respectively, at 6-9 months post-operatively. Minimal lower extremity strength deficits were demonstrated in pediatric male ACLR patients undergoing ITB harvest. KEY WORDS: Autograft, young ACL reconstruction, return to play, pediatrics.
