Tears of the abductor mechanism of the hip are well recognized, but poorly understood. Little is known of the effect of demographics and pathology on prevalence of abductor mechanism tears or the impact on clinical outcome. ⋯ Tears are increasingly prevalent in women of advancing years and lower socioeconomic status which should be considered when planning operative approach in this demographic. When recognised and repaired there is no difference in the clinical outcome for those with abductor mechanism tears of the hip.

Anatomical evaluation of the rectus femoris tendon and its related structures.
The purpose of this study was to evaluate the anatomical structure of the quadriceps tendon in detail for use as an anterior cruciate ligament (ACL) graft tendon. ⋯ If the RF tendon only is used as an ACL graft, surgeons should be cautious of the fact that the narrowest point of the RF tendon is located close to the patella. The entire quadriceps tendon is big enough to be used as an ACL graft. However, since the direction of the VL and VI tendons is different, the suitability of the quadriceps tendon as an ACL graft is questionable.

Randomized Controlled Trial Comparative StudyPrecision of novel radiological methods in relation to resurfacing humeral head implants: assessment by radiostereometric analysis, DXA, and geometrical analysis.
Resurfacing humeral head implants (RHHI) are used to preserve bone stock and restore normal anatomy in the osteoarthritic shoulder joint. The purpose of this study was: (1) to describe the use of novel radiological methods in relation to evaluation of RHHI; (2) to estimate the precision of these methods; and (3) to present preliminary clinical and radiological results at 6 months follow-up after Copeland and Global Cap RHHI. ⋯ Radiostereometric analysis and DXA can be used for evaluation of RHHI, but expectedly with a lower precision as compared to standards of TKA or THA. Geometric analysis of the prosthetic shoulder is precise. We interpret that the early radiological and clinical results of the two RHHI are comparable.

Comparative StudyRelative role changing of lateral collateral ligament on the posterolateral rotatory instability according to the knee flexion angles: a biomechanical comparative study of role of lateral collateral ligament and popliteofibular ligament.
This cadaveric study assessed the relative role of the lateral collateral ligament (LCL) and popliteofibular ligament (PFL) in limiting tibia external rotation. ⋯ The PFL and LCL play equally important roles in limiting external rotation at the knee extended position (0°, 30°) but the LCL contribution becomes smaller than PFL at the flexed position (60°, 90°).

Randomized Controlled Trial Comparative StudyPercutaneous distal metatarsal osteotomy versus distal chevron osteotomy for correction of mild-to-moderate hallux valgus deformity.
A lot of procedures were described for managing hallux valgus deformity. Percutaneous metatarsal osteotomies have received increasing recognition in the previous decade. The proposed benefits revolve primarily around the shorter surgical time, lower incidence of complications, and higher patient satisfaction. However, there is insufficient evidence to determine whether this technique is comparable to traditional open approaches. ⋯ The results of this study support the idea that percutaneous distal metatarsal osteotomy yields good functional and radiological result and is associated with a high degree of postoperative patient satisfaction.
