Distal femoral torsion positioning in total knee arthroplasty shows equal reliability using a computer-assisted system or a robotic arm.

Introduction: Computer-assisted or robot-assisted surgery in theory enables optimal positioning in total knee arthroplasty (TKA). The aim of the present study was to evaluate the rotational positioning of the femoral TKA implant using the ROSA Knee® robotic system. The hypothesis was that the accuracy of the rotation obtained by the ROSA Knee® robotic arm was comparable to that obtained by navigation.

Patellar resurfacing might not be mandatory in contralateral second total knee replacement even if performed during replacement of the first knee.

Introduction: The appropriateness or necessity of patellar resurfacing in total knee arthroplasty (TKA) is not clearly established. The objective of the present study was to compare the clinical and functional results of patients with bilateral involvement, operated on in one knee by TKA with patellar resurfacing and in the other knee by TKA without resurfacing. The hypothesis was that there was no difference in results between the two sides.

Ligamentoplasty with interposition of the proximal interphalangeal joint in the treatment of unicondylar osteochondral defects: a cadaveric feasibility study.

Background: Injuries to the proximal interphalangeal (PIP) joint are common and complex. However, the treatment of osteochondral defects of the head of the proximal phalanx has rarely been described. Herein, we propose a new technique for the management of unicondylar defects of the proximal phalanx that can restore joint amplitudes and provide PIP stability.

Implementation and results of an enhanced recovery (fast-track) program in total knee replacement patients at a French university hospital.

Introduction: In total knee replacement (TKR) surgeries, "fast-track" or enhanced recovery after surgery (ERAS) programs are being developed, but their impact on care pathway quality and safety has not been fully explored in the French literature. The present study aimed to compare results in TKR between fast-track and conventional pathways, addressing the following questions: (1) Are 90-day rates of complications, readmission and surgical revision higher with fast-track? (2) Is mean length of stay (LoS) shorter with fast-track? (3) Are postoperative pain and clinical results improved by fast-track? And, (4) are patients and care staff satisfied with these new programs?

Hypothesis: Implementing fast-track for TKR in a university hospital center is beneficial for the patient and does not impair the quality and safety of care.

Patients And Method: A case-control study was performed using a retrospective analysis of prospectively collected data.

Functional outcome of osteochondral autograft is equivalent in stable knee and in anterior cruciate ligament reconstruction.

Introduction: Anterior cruciate ligament (ACL) tears are associated in 10% to 20% of cases with extensive traumatic focal osteochondral damage. Ligament reconstruction may require osteochondral autograft for symptomatic osteochondral lesions. Combined ACL and chondral or osteochondral reconstruction is poorly evaluated in the literature; osteochondral reconstruction in stable knee better documented.
