Repair Augmentation of Unstable, Complete Vertical Meniscal Tears With Bone Marrow Venting Procedure: A Prospective, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study.

PURPOSE: To compare the effectiveness and safety of meniscal repair in 2 groups of patients: meniscal repair with biological augmentation using a bone marrow venting procedure (BMVP) of the intercondylar notch versus meniscal repair only. METHODS: This single-center, prospective, randomized, double-blind, placebo-controlled, parallel-arm study included 40 patients (21 menisci in control, 23 in BMVP group) with complete vertical meniscus tears. Patients underwent all-inside and outside-in meniscal repair and a concomitant BMVP of the intercondylar notch or meniscal repair alone during an index arthroscopy. The primary endpoint was the rate of meniscus healing in the 2 groups assessed during a second-look arthroscopy (at week 35). The secondary endpoints were changes in the International Knee Documentation Committee score, Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index, and visual analog scale in the 2 groups at 30 months. RESULTS: After 36 weeks, the meniscus healing rate was significantly higher in the BMVP-treated group than in the control group (100% vs. 76%, P = .0035). Functional outcomes were significantly better 30 months after treatment than at baseline in both groups. The International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index, and visual analog scale scores were significantly better in the BMVP-treated group than in the control group. No adverse events were reported during the study period. CONCLUSIONS: Our blinded, prospective, randomized, controlled trial on the role of BMVP augmentation in meniscus repair, indicates that BMVP augmentation results in a significant improvement in the rate of meniscus healing (100% vs. 76%, P = .0035). The risk of adverse events related to augmentation with BMVP of the arthroscopic meniscal repair is very low. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

A Prospective, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study Evaluating Meniscal Healing, Clinical Outcomes, and Safety in Patients Undergoing Meniscal Repair of Unstable, Complete Vertical Meniscal Tears (Bucket Handle) Augmented with Platelet-Rich Plasma.

OBJECTIVE: The present study aimed to investigate the effectiveness and safety of platelet-rich plasma (PRP) application in arthroscopic repair of complete vertical tear of meniscus located in the red-white zone. METHODS: This single center, prospective, randomized, double-blind, placebo-controlled, parallel-arm study included 37 patients with complete vertical meniscus tears. Patients received an intrarepair site injection of either PRP or sterile 0.9% saline during an index arthroscopy. The primary endpoint was the rate of meniscus healing in the two groups. The secondary endpoints were changes in the International Knee Documentation Committee (IKDC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and analog scale (VAS) in the two groups at 42 months. RESULTS: After 18 weeks, the meniscus healing rate was significantly higher in the PRP-treated group than in the control group (85% versus 47%, P = 0.048). Functional outcomes were significantly better 42 months after treatment than at baseline in both groups. The IKDC score, WOMAC, and KOOS were significantly better in the PRP-treated group than in the control group. No adverse events were reported during the study period. CONCLUSIONS: The findings of this study indicate that PRP augmentation in meniscus repair results in improvements in both meniscus healing and functional outcome.

Difficulties in Treating Complex Knee Injuries with Fracture of Posterior Tibial Plateau.

BACKGROUND: The aim of the study was to assess the outcomes of surgical treatment of complex knee injuries with a posterior inverted-L approach to the knee joint. MATERIAL AND METHODS: The study retrospectively enrolled 13 patients who underwent surgical treatment due to knee injuries with posterior tibial plateau fractures in 2015-2017. Pre-operative planning was based on antero-po-sterior and lateral X-rays and CT images. The fracture was assessed according to Luo's three-column classification. Radiographic postoperative assessment was based on lower limb (standing) X-rays and measurements of the MPTA, aPPTA, JLCA, and aFaT angles in the operated and healthy limbs. Clinical assessment was based on the IKDC, KOOS, and Tegner-Lysholm Knee Scoring Scale. RESULTS: Mean follow-up duration was 11.5 months (4-25 months). Anatomical joint surface reduction was achiev-ed in 12 patients and bone union was present in all patients. A posterior inverted-L approach was used in 9 pa-tients and combined approaches in 8 patients. According to the three-column classification, single-column fractures were found in 3 patients, two-column fractures in 4, and three-column fractures in 6 patients. The KOOS was 82%, the IKDC score was 80%, and the Tegner-Lysholm score was 82 points. Radiographic assessments of the operated knee joints showed an MPTA of 88.64 degrees, aPPTA of 79.78 degrees, JLCA of 0.8 degrees, and aFaT of 7.9 degrees. CONCLUSIONS: 1. Anatomical reduction and stable fixation of posterior plateau fractures of the proximal tibia are crucial in fracture management. 2. A posterior inverted-L approach is very useful when treating posterior tibial plateau fractures.

Posttraumatic Oedema in Lower Limbs. Advances in Understanding Etiopathogenesis and Treatment. Review Article.

Mechanical injury to soft tissues and bones of the lower limbs may be complicated by thrombosis and oedema. Treatment of posttraumatic oedema in the lower limbs can be difficult and protracted and rarely leads to complete recovery. The pathogenesis of posttraumatic oedema has not been fully elucidated. This paper presents the aetiopathogenesis of posttraumatic oedema in the lower limbs and a review of relevant literature in English and Polish of the last 5 years, describing therapy outcomes and potential perspectives for develop ment.

Osteochondrosis of the capitellum of the humerus (Panner's disease, Osteochondritis Dissecans). Case study.

The article presents a case of an adolescent patient suffering from osteochondritis of the humeral capitellum. Early symptoms of this disease appeared at an age typically associated with the onset of both Panner's disease and Osteochondritis Dissecans (OCD) of the humeral capitellum. About two years after the onset of the early symptoms, the patient reported to a specialised clinic. He was followed up for almost two years and was hospitalised and underwent surgical treatment during that period. Both diseases bear multiple similarities, which may entail diagnostic errors. The paper presents differences between these two similar clinical entities, in particular in terms of treatment and prognosis. Essential details potentially allowing for early diagnosis and classification of both conditions are described and discussed. Resolving the discussion may significantly contribute to improving performance and quality of life of patients suffering from necrosis of the humeral capitellum.

[Arthroscopy scapulothoracic articulation (introduction of this method)]. / Endoskopia przestrzeni lopatkowo-zebrowej (prezentacja metody).

The authors have introduced arthroscopy of scapulothoracic. They have treated 37 years old patient who suffer from bursitis with pain and crepitus. They have used arthroscopy procedure. The first publication about scapulothoracic arthroscopy was in 1992. The method has been written very rarely by foreigner authors in medical journals.
