Over half of postpartum women experience pelvic ring or hip pain, with multiple anatomic locations involved. The sacroiliac joints, pubic symphysis, lumbar spine and pelvic girdle are all well documented pain generators. However, despite the prevalence of postpartum hip pain, there is a paucity of literature regarding underlying soft tissue intra-articular etiologies. The purpose of this systematic review is to document and assess the available evidence regarding underlying intra-articular soft tissue etiologies of peri- and postpartum hip pain.

Three online databases (Embase, PubMed and Ovid [MEDLINE]) were searched from database inception until April 11, 2021. The inclusion criteria were English language studies, human studies, and those regarding symptomatic labral pathology in the peri- or postpartum period. Exclusion criteria were animal studies, commentaries, book chapters, review articles and technical studies. All titles, relevant abstracts and full-text articles were screened by two reviewers independently. Descriptive characteristics including the study design, sample size, sex ratio, mean age, clinical and radiographic findings, pathology, subsequent management and outcomes were documented. The methodological quality of the included studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) instrument.

The initial search identified 2472 studies. A systemic screening and assessment of eligibility identified 5 articles that satisfied the inclusion criteria. Twenty-two females were included. Twenty patients presented with labral pathology that necessitated hip arthroscopy with labral debridement or repair with or without acetabuloplasty and/or femoroplasty. One patient presented with an incidental labral tear in the context of osteitis condensans illi. One patient presented with post-traumatic osteoarthritis necessitating a hip replacement. The mean MINORS score of these 5 non-comparative studies was 2.8 (range 0-7) demonstrating a very low quality of evidence.

The contribution of intra-articular soft tissue injury is a documented, albeit sparse, etiology contributing to peri- and postpartum hip pain. Further research to better delineate the prevalence, mechanism of injury, natural history and management options for women suffering from these pathologies at an already challenging time is necessary to advance the care of these patients.

To document and assess the available evidence regarding single bundle, hamstrings autograft preparation techniques for Anterior Cruciate Ligament reconstruction (ACLR) and provide graft preparation options for different clinical scenarios.

Three online databases (Embase, PubMed and Ovid [MEDLINE]) were searched from database inception until April 10, 2021. The inclusion criteria were English language studies, human studies, and operative technique studies for single bundle hamstrings autograft preparation for ACLR. Descriptive characteristics, the number of tendons, number of strands, tendon length, graft length and graft diameter were recorded. The methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) instrument and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system for non-randomized and randomized studies, respectively.

The initial search yielded 5485 studies, 32 met the inclusion criteria. The mean MINORS score across all nonrandomized studies was 8.2 (standard deviation, SD 6.6) indicating an overall low quality of evidence. The mean MINORS score for comparative studies was 17.4 (SD 3.2) indicating a fair quality of evidence. The GRADE assessment for risk of bias in the randomized study included was low.

There were 2138 knees in 1881 participants, including 1296 (78.1%) males and 363 (21.9%) females recorded. The mean age was 30.3 years. The mean follow-up time was 43.9 months when reported (range 16-55 months). Eleven studies utilized the semitendinosus tendon alone, while 21 studies used both semitendinosus and gracilis tendons. There were 82 (3.8%) two-strand grafts, 158 (7.4%) three-strand grafts, 1044 (48.8%) four-strand grafts, 546 (25.5%) five-strand grafts, and 308 (14.4%) six-strand grafts included. Overall, 372 (19.7%) participants had a single-tendon ACLR compared to 1509 (80.2%) participants who had a two-tendon ACLR.

The mean graft diameter was 9.4mm when reported. The minimum semitendinosus and gracilis tendon lengths necessary ranged from 210-280mm and 160-280mm respectively. The minimum graft length necessary ranged from 63-120mm except for an all-epiphyseal graft in the paediatric population that required a minimum length of 50mm. The minimum femoral, tibial, and intra-articular graft length ranged from 15-25mm, 15-35mm and 20-30mm respectively. Thirteen studies detailed intra-operative strategies to increase graft size such as adding an extra strand or altering the tibial and/or femoral fixation strategies to shorten and widen the graft.

Two studies reported ACL reinjury or graft failure rate. One study found no difference in the re-injury rate between four-, five- and six-strand grafts (p = 0.06) and the other found no difference in the failure rate between four- and five- strand grafts (p = 0.55). There was no difference in the post-operative Lysholm score in 3 studies that compared four- and five-strand ACLR. One of the five studies that compared post-operative IKDC scores between graft types found a difference between two- and three- strand grafts, favoring three-strand grafts.

There are many single bundle hamstrings autograft preparation techniques for ACLR that have been used successfully with minimal differences in clinical outcomes. There are different configurations that may be utilized interchangeably depending on the number, size and length of tendons harvested to obtain an adequate graft diameter and successful ACLR.
