“…Critical application of the inclusion and exclusion criteria to those articles yielded 11 studies (Fig 1). 5,6,13,[15][16][17][18][19][20][21][22] The features of each of the included studies are listed in Table 4. Interestingly, there were no studies that had directly compared clinical outcomes after remnant-preserving PCLR with those after standard PCLR, and there were 2 studies with long-term follow-up.…”

“…As a result, many centres routinely perform reconstructions of the PCL. Based on the initial diagnosis and associated structures, different surgical techniques and different grafts are used [3-12]. With surgical treatment, good clinical results and improved subjective patient outcomes can be achieved [13-17].…”

BackgroundWith incorrect or even without treatment, acute injuries of the posterior cruciate ligament (PCL) can lead to chronic instability of the knee joint. After delayed treatment, negative occupational changes and reduced quality of life can occur. These aspects have not yet been investigated. The purpose of this study was to evaluate occupational consequences after isolated reconstruction in cases of chronic PCL insufficiency.Findings12 patients treated with PCL reconstruction in a single bundle technique, using hamstring tendon grafts, were evaluated. All patients were operated upon at least 3 months after injury. Mean time of follow-up was 51 ± 18.2 months (14–75). Radiological assessment (Telos stress device) showed a side comparison of total translation of 4.5 ± 2.6 mm. Occupational consequences have been evaluated by the classification system “REFA”. Median time incapacity for work was 8 weeks. Nearly all patients achieved the mental status of the normal population (SF-36), but physical status was still restricted. A pre- to postoperative improvement of the clinical scores could be seen: Lysholm-Score: 46.4 ± 17.3 to 84.7 ± 14.1, HSS-Score: 74.3 ± 10.5 to 88.3 ± 10.7. Postoperative evaluated scores were: Tegner score: 4.8 ± 1.2, IKDC score: 80.0 ± 16.2, VPS: 3.4 ± 2.7. Patients with low physical load in their workplace described significantly better clinical results in every clinical score (p < .05) and less pain than patients with high physical load prior to the accident (VPS: REFA < 2: 2.4 ± 2.6, REFA ≥ 2: 5.5 ± 1.7; p < 0.05).ConclusionsOperative treated patients with a chronic PCL insufficiency achieve an improvement of the clinical result. Patients with low physical load at their workplace achieve less restrictions.

The healing mechanism of cruciate ligaments is not well elucidated. Crosstalk between adjacent tissues in the knee joint plays an important role in wound healing and tissue regeneration, but the gelatinase modulation in posterior cruciate ligament fibroblasts (PCLfs) and synovial cells (SCs) based on co-culture is still elusive. The present study sought to systematically elucidate the gelatinase modulation in both PCLfs and SCs based on in vitro co-culture and in a rabbit PCL-injury model in vivo. It was found that injured PCLfs and SCs can secrete high gelatinases after co-culture. Cytokines promote greater gelatinase secretion by both injured PCLfs and SCs in the form of monomers and dimers. Pathway inhibitors can reduce injury-induced gelatinase activities, but the presence of cytokines restores the higher activity. Inhibitor cocktails can reduce gelatinase expression to a normal level even in the presence of cytokines. Growth factors promote wound healing of the injured PCL by enhancing cell migration, proliferation and collagen synthesis, but also upregulate gelatinases. Modified inhibitor cocktails containing growth factor can also reduce gelatinase expression to a normal level. This gelatinase modulation was also verified in a rabbit PCL injury model in vivo. Together, the results aids understanding of the mechanism of gelatinase modulation in injured PCL ligament post-crosstalk with synovium and infers that the gelatinases could be a potential as a therapeutic target for acute ligament injury.
