Assessment of learning in simulator-based arthroscopy training with the diagnostic arthroscopy skill score (DASS) and neurophysiological measures
ConclusionThe analysis of cognitive workload changes during simulation-based arthroscopy training revealed a significant correlation between the trainees ’ DASS scores and fNIRS data. This correlation suggests the potential use of fNIRS data and DASS scores as additional metrics to create adaptive training protocols for each participant. By incorporating these metrics, the training process can be optimized, leading to more efficient arthroscopic tr aining and better preparedness for clinical operations.Level of evidenceIII.

Five or more gender- and size-diverse customizations of distal femur prostheses are needed to improve fit for Chinese knees
ConclusionsChinese distal femur morphology, as analyzed using 3D techniques, varies significantly between genders and when compared with international data. For improved patient fit, the creation of five or more distal femur prostheses, diversified by gender and size and informed by the associated morphological parameters, is recommended.Level of evidenceIV.

Long-lasting decreased pain threshold negatively affects functional recovery after arthroscopic rotator cuff repair
ConclusionPatients experiencing poor postoperative clinical outcomes exhibited prolonged lowered PPT. Lowered PPT due to sensitization may adversely affect functional recovery and pain perception. Elevating PPT using weak opioids improved clinical outcomes during the acute perioperative period after ARCR.Level of evidenceIII. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Fixed lateral unicompartmental knee replacement is a reliable treatment for lateral compartment osteoarthritis after mobile-bearing medial unicompartmental replacement
ConclusionThe FLO is a reliable treatment for lateral osteoarthritis following medial UKR. At 5  years there was a 100% survival of the FLO with a mean OKS of 40.Level of evidenceIV, Prospective Case Series. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Substantial influence of psychological factors on return to sports after anterior shoulder instability surgery: a systematic review and meta-analysis
ConclusionsPsychological factors have a substantial impact on the rate of return to sports after anterior shoulder instability surgery. Patients who returned to sports had significantly higher psychological readiness than those who did not return to sports. Based on these results, healthcare professionals should include psychological and functional measurements when assessing athletes ’ readiness to return to sports.Level of evidenceLevel IV.

Quadriceps tendon malalignment is an independent anatomical deformity which is the primary abnormality associated with lateral facet patellofemoral joint osteoarthritis
ConclusionThese studies have confirmed the ability to accurately determine QTA on CT scans. The normal values indicate that the QTA is highly variable and unrelated to bony anatomy. The comparative study has determined that QTA is clinically relevant and a lateralised QTA is the dominant predictor of severe LFPFJOA. This deformity should be considered when assessing patella maltracking associated with patella osteoarthritis, patella instability and arthroplasty.Level of evidenceIII (retrospective cohort study).

Satisfaction after total knee arthroplasty: a prospective matched-pair analysis of patients with customised individually made and off-the-shelf implants
ConclusionPatient satisfaction was high with no differences between patients with CIM and OTS TKA. Both implant systems improved function, pain and health-related quality of life. Patients with CIM TKA showed superior results in demanding activities as measured by the HAAS.Level of evidenceII, prospective cohort study. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Arthroscopic Latarjet yields better union and prevention of instability compared to arthroscopic  bony Bankart repair in shoulders with recurrent anterior instability: a systematic review
ConclusionCompared to arthroscopic Latarjet, arthroscopic bony Bankart repair results in significantly (i) higher rates of recurrent instability (14% vs 4%), (ii) lower union rates (63% vs 98%), but (iii) slightly lower pain on VAS (0.45 vs 1.17). There were no differences in complication rates, clinical scores, or postoperative ranges of motion.Level of evidence IV. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Constitutional alignment predicts medial ligament balancing in mechanically aligned total knee arthroplasty for varus knees
ConclusionLigament balancing using MNP was determined by constitutional alignment rather than medial soft tissue contracture. Patients with constitutional varus who had a larger medio-lateral gap difference in extension also had a higher incidence of having had MNP to both anterior and posterior sMCL fibres.Level of evidenceRetrospective comparative study, level IV.

Psychosocial interventions seem redact kinesiophobia after anterior cruciate ligament reconstruction but higher level of evidence is needed: a systematic review and meta-analysis
ConclusionsPsychosocial interventions can alleviate kinesiophobia in patients with primary ACLR. Although the limited number of reviewed studies and their methodological limitations precludes drawing a definitive conclusion regarding the effectiveness of psychosocial interventions on kinesiophobia, these promising findings can serve as a basis for developing psychological strategies to manage kinesiophobia in patients with primary ACLR and can also guide future research this issue.Level of evidenceII.Trial registrationThis trial is registered in PROSPERO on December 2021 (CRD42021282413).
