Use of ultrasonography to evaluate the dynamics of the infrapatellar fat pad after anterior cruciate ligament reconstruction: a feasibility study

ConclusionWhen assessed 3  months after ACL reconstruction, the thickness of the superficial part of the IPFP at 90° knee flexion and the thickness change ratio of the IPFP were both significantly lower in the reconstructed knees than in the contralateral knees.

We describe an ultrasound-guided anterolateral ligament (ALL) reconstruction technique that uses the gracilis tendon and can be added to any anterior cruciate ligament reconstruction technique. Preoperative ultrasound imaging is used to view the ruptured ALL and confirm the location of bony landmarks. Two minimally invasive incisions are made: one posterior to the lateral epicondyle and one posterior to the Gerdy tubercle. After anterior cruciate ligament graft fixation, the 2-strand gracilis tendon is introduced from the tibial incision, under the fascia lata, toward the femoral incision. The ALL graft is secured to the f...

CONCLUSION: Addition of clonidine to ropivacaine in USG guided adductor canal block led to significant prolongation of pain free period though pain score at rest and movement, and rescue analgesic requirement, did not differ. PMID: 31080007 [PubMed - as supplied by publisher]

ConclusionST activation is significantly lower in surgical than control limbs during eccentric knee flexor exercise 1 –6 years after ACLR with ST graft. Lower levels of ST activation may partially explain this muscle’s persistent hypotrophy post ACLR and have implications for the design of more effective rehabilitation programs.Level of evidenceIV.

In conclusion, our results suggest that the addition of BFR to exercise contributes to neuromuscular adaptations only when RT is performed with low-load. Furthermore, we found a significant association between the changes in [HHb] (i.e., metabolic stress) and increases in muscle CSA from T2 to T3 only for the LL-BFR, when muscle edema was attenuated. Introduction Resistance training- (RT) induced changes in muscle strength are partially due to increases in muscle cross-sectional area (CSA) (i.e., muscle hypertrophy) and changes in muscle architecture (e.g., increase in the pennation angle of muscle fibers) (Aagaard...

The objective of this study is to evaluate the reproducibility of the patellar tendon measurements by ultrasound and compare them with anatomical measurements, both in cadaver and patients undergoing ACLR. The study consists of two phases; first anatomical study in cadaver. The ultrasound measurement was performed by determining the length, width and thickness of the patellar tendon, both by ultrasound and anatomical dissection. The second phase is a cohort of 42 patients pending surgical ACLR. Previous ultrasound and intraoperative measurements were obtained. Regarding the anatomical study, statistical analysis did not sh...

We present two cases of saphenous neuralgia, one after total knee arthroplasty and the other after anterior cruciate ligament reconstruction, that were adequately treated with ultrasound-guided saphenous nerve blocks distal to the adductor canal. Early recognition and treatment of saphenous neuralgia is essential to prevent persistent disabling pain, which significantly affects patients' quality of life.
