Bone bridge technique for lateral meniscal allograft transplantation: no difference in clinical outcome compared to the soft tissue technique
ConclusionLateral MAT has a high success rate for symptomatic meniscal deficiency with significant benefits irrespective of the fixation technique. There is no advantage in performing the more technically demanding BB technique over ST fixation.Level of evidenceLevel 2. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Valgus alignment of the femoral component is associated with higher revision rates 10  years after TKA
ConclusionsPrimary TKA showed significantly higher revision rates when the femoral component was placed in  >  3° of valgus (mLDFA <  87°). In contrast, postoperative overall residual varus alignment (HKA) and varus alignment of the tibial component were not related to higher revision rates at a minimum 10-year follow-up after TKA. These findings should be considered when choosing component position in individualised TKA.Level of evidenceIII. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

The adductor magnus tendon is a viable option for medial patellofemoral ligament reconstruction, but with a busy surrounding neurovascular topography
ConclusionThe adductor magnus tendon is a viable option for the dynamic reconstruction of the MPFL. Knowledge of the surrounding busy neurovascular topography is paramount for a procedure typically performed in a minimally invasive way. The study results are clinically relevant, as they suggest that tendons should be shorter than the minimum distance from the nerve. If in some cases the length of the MPFL is longer than the distance of the ADM from the nerve, the results suggest that a partial dissection of the anatomical structures might be needed. Direct visualization of the harvesting region might be considered in such ...

The “Bankart knee”: high-grade impression fractures of the posterolateral tibial plateau lead to increased translational and anterolateral rotational instability of the ACL-deficient knee
ConclusionThis study demonstrates that high-grade impression fractures of the posterolateral aspect of the tibial plateau increase the instability of ACL-deficient knees and result in an increase in translational and anterolateral rotational instability.

In closed wedge distal femur osteotomies for correction of valgus malalignment overcorrection of mLDFA should be avoided
ConclusionCorrection of valgus knees using closed wedge DFO leads to good clinical results. A postoperative mLDFA of 85 –90° results in superior clinical outcome compared to mLDFA> 90 °. Joint-line obliquity should be avoided using double level osteotomy, if needed.Level of evidenceIII. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Meniscal repair failure following concurrent primary anterior cruciate ligament reconstruction: results from the New Zealand ACL Registry
ConclusionThe use of a hamstring tendon autograft, younger age and the presence of medial compartment cartilage injury are risk factors for medial meniscal repair failure, whereas younger age, low surgeon volume and a transtibial drilling technique are risk factors for lateral meniscal repair failure.Level of evidenceLevel II.

Restoration or relative overcorrection of pre-arthritic coronal alignment leads to improved results following medial unicompartmental knee arthroplasty
ConclusionPre-arthritically aligned knees and knees with relative overcorrection from their pre-arthritic alignment following medial UKA demonstrated improved mid-term outcomes and survivorship compared to knees with relative under correction from their pre-arthritic alignment. These results encourage restoring or relatively overcorrecting pre-arthritic alignment to optimize outcomes following medial UKA, and caution against under correction from the pre-arthritic alignment.Level of evidenceIV, case series.

Optimism and pessimism are antithetically associated with post-operative knee function in patients ’ undergoing total knee arthroplasty
ConclusionOptimism was positively associated with pre-operative joint function and, more importantly, post-operative functional outcome in TKA, while pessimism was associated with the opposite. Assessing patients ’ general personality traits prior to surgery to identify pessimistic patients, hence being at risk for poor outcome in TKA, should be considered to react to the patients’ special needs and possible pessimistic expectations, i.e., through a cognitive–behavioral intervention, to potentially inc rease optimism and hereby post-operative outcome in TKA.Level of evidencePrognostic Level III.

Ultrasonographic echo intensity in the medial femoral cartilage is enhanced prior to cartilage thinning in women with early mild knee osteoarthritis
ConclusionsThe echo intensity of the medial femoral cartilage was high in patients with KL grade 2, without decreased thickness. Our findings suggested that higher echo intensity is a feature of early cartilage degeneration in mild knee OA. Further studies are needed to establish this feature as a useful screening parameter of early cartilage degeneration in knee OA.Level of evidenceLevel III.

No difference in revision risk between autologous hamstring graft less than 8  mm versus hybrid graft 8 mm or larger in anterior cruciate ligament reconstruction
ConclusionIn a US-based cohort of ACLR patients aged  ≤ 25 years, we failed to observe any differences in aseptic revision risk for HA <  8 mm compared to HY ≥ 8 mm. Augmentation of a HA as small as 7 mm is not necessary to prevent a revision surgery.Level of evidenceLevel III. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

Comprehensive arthroscopic management without axillary nerve release or subacromial decompression achieves satisfactory and durable results in young patients with glenohumeral osteoarthritis
ConclusionsThis study showed that the CAM procedure without direct axillary nerve neurolysis or subacromial decompression might be a valid alternative in active patients with advanced GHOA to improve shoulder function (aROM and scores), decrease pain, and delay arthroplasty. This technique showed good subjective functional scores, high patient satisfaction, and a low rate of complications.Level of evidenceIV. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

A guide to appropriately planning and conducting meta-analyses: part 2 —effect size estimation, heterogeneity and analytic approaches
AbstractMeta-analyses by definition are a subtype of systematic review intended to quantitatively assess the strength of evidence present on an intervention or treatment. Such analyses may use individual-level data or aggregate data to produce a point estimate of an effect, also known as the combined effect, and measure precision of the calculated estimate. The current article will review several important considerations during the analytic phase of a meta-analysis, including selection of effect estimators, heterogeneity and various sub-types of meta-analytic approaches.
