Two to nineteen years follow-up of arthroscopic meniscal repair using the outside-in technique: a retrospective study

PURPOSE: To perform a long-term follow-up evaluation of the outside-in technique of arthroscopic meniscal repair. TYPE OF STUDY: Retrospective study. METHODS: Between the years 1986 and 2002, 93 cases of arthroscopic meniscal repair using the outside-in technique have been operated by the senior author (F.L.). Forty-one patients were available for the follow-up evaluation with a mean follow-up of 11.71 years. The International Knee Documentation Committee (IKDC), the modified Lysholm score, the SF-36 (short form 36) health survey score, a visual analogue scale (VAS) for assessment of patients' satisfaction and another VAS for assessment of patients' pain were used retrospectively to evaluate the patients. We also used the Kellgren and Lawrence (K/L) classification of osteoarthritis to evaluate the preoperative X-rays and the X-rays done at the time of the follow-up evaluation. Failure was defined as having a meniscectomy procedure post-operatively. Results: From the 93 patients, 52 could not be retrieved for the follow-up evaluation, while 41 were available for it; 36 patients were clinically successful and 5 were considered as failure. Thirty-six patients were classified as grade "A" in the objective IKDC score, mean modified Lysholm score was 87.29 (SD 16.43), while mean SF-36 score was 85.73 (SD 14.17). The results of the VAS for operation satisfaction ranging from -10 to +10 revealed that the mean of the answers was 8.05 (SD 2.99). The results of the VAS for pain ranging from 0 to 10 revealed that the mean of the patients' pain at the time of the follow-up evaluation was 1.8 (SD 2.42). Twenty out of 24 (only 24 preoperative X-rays were available) were classified as having no osteoarthritis pre-operatively, whereas only 12 out of the 41 patients were classified as having no osteoarthritis (normal) at the time of the follow-up evaluation according to the K/L classification which indicates progression of osteoarthritis. No complications related to the outside-in arthroscopic meniscal repair procedure were reported. CONCLUSION: We conclude that arthroscopic meniscal repair using the outside-in technique is a safe surgical procedure with a good clinical outcome.     

A retrospective analysis of risk factors for meniscal co-morbidities in anterior cruciate ligament injuries

Background:

The association of meniscal cartilage injury with anterior cruciate ligament (ACL) injury is well documented in literature. The aim of this study was to examine the relative risk factors for meniscal pathology at the time of arthroscopic ACL reconstruction.

Materials and Methods:

A review of the case records including both in-patient and out-patient charts of all patients who underwent arthroscopic ACL reconstruction during the preceding 3 years was performed by either of the authors. The relative incidences of associated meniscal pathologies were analyzed in correlation with age, side of injury, time to surgery, mode of injury, and gender as the risk factors. Statistical analysis was performed to obtain individual data correlation.

Results:

A total of 192 patients underwent ACL reconstruction during the 3-year time frame. Of these, complete data sets were available for 129 patients. Analysis revealed that the only factor that was statistically significant in raising the risk of meniscal pathology was the time to surgery (P = 0.001). There was a significant increase in medial, lateral, and both meniscal tears noted in cases operated beyond 24 weeks. Further, the incidence of medial meniscal tears as well as lateral meniscal tears increased with delay in presentation for surgery (P = 0.004). Mode of injury, age at presentation, sex, and side were not significantly associated with an increased incidence of meniscal pathology.

Conclusion:

The single factor that significantly affects incidence of meniscal co-morbidity in ACL injury is the delay in presentation (i.e. the time to surgery). The incidence of lateral meniscal tears as well as medial meniscal tears increased with delay in surgery. This should guide us toward recommending all patients irrespective of age, gender, or mode of injury to undergo early reconstruction, thereby reducing the likelihood of developing meniscal pathology.     

Arthroscopic partial meniscectomy

Meniscal tears are among the most common problems surgically addressed in the practice of knee surgery. Arthroscopic partial meniscectomy has become the standard in managing meniscal damage not suitable for repair or allograft replacement. Current techniques involve low morbidity, rapid rehabilitation, and early return to functional activities. However, recent studies suggest that the optimistic early results of arthroscopic partial meniscectomy may deteriorate over time.

Characterization and comparison of rat monosodium iodoacetate and medial meniscal tear models of osteoarthritic pain

Osteoarthritis (OA) is a degenerative form of arthritis that can result in loss of joint function and chronic pain. The pathological pain state that develops with OA disease involves plastic changes in the peripheral and central nervous systems, however, the cellular mechanisms underlying OA are not fully understood. We characterized the medial meniscal tear (MMT) surgical model and the intra‐articular injection of monosodium iodoacetate (MIA) chemical model of OA in rats. Both models produced histological changes in the knee joint and associated bones consistent with OA pathology. Both models also increased p38 activation in the L3, but not L4 dorsal root ganglia (DRG), increased tyrosine hydroxylase immunostaining in the L3 DRG indicating sympathetic sprouting, and increased phosphorylated (p)CREB in thalamic neurons. In MIA‐OA, but not MMT‐OA rats, p38 and pERK were increased in the spinal cord, and pCREB was enhanced in the prefrontal cortex. Using in vivo electrophysiology, elevated spontaneous activity and increased responsiveness of wide dynamic range neurons to stimulation of the knee was found in both models. However, a more widespread sensitization was observed in the MIA‐OA rats as neurons with paw receptive fields spontaneously fired at a greater rate in MIA‐OA than MMT‐OA rats. Taken together, the MIA and MMT models of OA share several common features associated with histopathology and sensitization of primary somatosensory pathways, but, observed differences between the models highlights unique consequences of the related specific injuries, and these differences should be considered when choosing an OA model and when interpreting data outcomes. © 2018 Orthopaedic Research Society.
