Treatment of the hyaline cartilage pathology is a problem regarded by current orthopedics as urgent. Surgery aimed at local cartilage defects correction is one of the most difficult tasks a surgeon can have today.

Osteochondritis desiccans (Koenig's disease) in femoral condyle makes up 2% of all knee joint disorders. The pathology mainly affects people 11 to 13 and 20 to 40 years old.

Every year, surgeons in Europe perform over 300,000 operations aimed at correction of local intraarticular cartilage defects of the knee joint [1]. Many of the previously popular surgery methods applied to remedy the disorder, like cartilaginous plate anchoring, subchondral bone tunneling etc, have proved ineffective and are quite outdated.

In 80-85% of cases, osteochondritis desiccans manifests around the medial femoral condyle; in 10-20% of cases — around lateral femoral condyle; in 4% — on the articular surface of patella and in 0.5-0.7% of cases — around the femoral intercondylar groove. In 14-24% of cases, Koenig's disease is bilateral [2].

The reasons behind damage to cartilage accompanying osteochondritis desiccans are not quite clear. The list of these reasons may include constitutional and genetic factors, ischemia, traumas, bone overload disorders, ossification disorders etc [3]. Probably, Koenig's disease is the result of ischemia and local necrosis of the subchondral bone that spreads onto cartilage. Development of osteochondritis desiccans leads to separation of the subchondral bone's necrotic fragment and its transfer to the joint's cavity.

There are many diverse surgery approaches to the Koenig's disease, and some of them imply making use of advanced biotechnology; however, numerous related questions remain unanswered [4-8]. Simultaneous osteochondral reconstruction (and the necessity thereof) is one of the subjects of discussion. Lack of a common opinion and related standards complicates validation of methods chosen to treat a case of Koenig's disease, especially in juvenile patients with open physes.

Unfortunately, the choice our surgeons have today when treating osteochondritis desiccans is very limited. The reason

behind such a state of affairs is unavailability of a wide range of techniques and tools offered by current biological and cellular technologies. National R&D centers have not yet offered viable alternatives to the imported biomaterials, the cost of which makes them inexpedient in the context of routine treatments in Russian hospitals.

Analysis of the long-term outcomes of bone-cartilage autotransplantation ("mosaic" chondroplasty, commonly used by Russian practitioners) has revealed the drawbacks of this approach: 1) frequently observed non-restoration of the joint surfaces' congruence, as well as that of the defect itself; 2) problematic consequences seen around the patello-femoral articulation. One of the main causes of complications arising during surgery on extensive osteochondral defects of femoral condyles is the deficit of osteoplastic material.

This paper presents the optimal algorithm of surgical treatment of femoral condyle osteochondritis desiccans (depending on the cartilage damage severity) and validation thereof.

Study Design

To develop the optimal treatment algorithm addressing the disorder in question, as well as validation points thereof, we have analyzed the results observed in 184 patients with various chronic knee injuries (full-thickness local cartilage and osteochondral) treated from 1995 to 2017 in Hospital #1 named after N.I. Pirogov.

The patients were divided into two groups, treatment (1st) and control (2nd). The first group included 86 patients; they were treated following current local cartilage defects surgical correction protocols (mono or "mosaic" bone/cartilage auto- or allotransplantation, autologous matrix-induced chondrogenesis - AMIC - implantation of collagen matrix with or without bone grafting) [12].

The second group consisted of 98 patients; their treatment followed older local cartilage defects correction practices (abrasive chondroplasty, subchondral bone micro-fractures, tunneling) [2-5, 6].

Duration of the condition was estimated from case records, i.e. from the day a patient first noticed the disorder to the day that patient was diagnosed with Koenig's disease.

Examination and treatment results assessment methods employed: clinical and functional checkup, MRI and multispiral computed tomography (MSCT); scales used to assess condition in pre- and postoperative periods: ICRS physical activity scale (ICRS — International Cartilage Repair Society), VAS (visual analogue scale), WOMAC knee score [2].

Hounsfield scale was used to analyze and assess treatment results as shown by the CT scans of the patients' knee joints. MOCART scale was employed to assess the MRI scans [9-11].

Inclusion criteria: male and female patients aged 15 to 60 years (mean age 40 ± 1.6 years); chronic full-thickness knee cartilage defects, 3rd and 4th stage (ICRS classification).

Exclusion criteria: age under 15 or over 60; 1st or 2nd stage of the knee cartilage defects (not full-thickness, fresh injury).

We have analyzed the long-term (up to 8 years) treatment results observed in 70 patients (81.4%) of the treatment group and 78 patients (79.6%) of the control group. This is not the entire sample; the reasons behind the discrepancy are unavailability of a number of patients and recency of surgery in some cases.

Below, we outline the knee osteochondritis desiccans surgery algorithm we have developed and employ in our hospital; it is based on the aforementioned research effort.

Knee Osteochondritis Desiccans: Surgical Correction

1. Patients with open physes

Today, Russian hospitals have a number of options when it comes to surgical correction of local osteochondral defects of femoral condyles, intercondyle groove, kneecap.

We believe that osteochondral transplantation is an inappropriate choice for juvenile patients with open physes. Anchoring the detached necrotic osteochondral plate is also a prospectless option. AMIC, collagen matrix implantation onto necrotic subchondral bone, will not result in regeneration of the latter. We have verified that subchondral bone continues to decay when AMIC does not imply using a bone plate. See more on this technology below.

Thus, the method of choice for patients of this age group is tunneling, i.e. drilling holes in the subchondral bone to stimulate repairs done by mesenchymal stem cells that enter through those holes [12]. Lately, we have been doing that arthroscopically, using a 3.5 mm triangular bit drill with a stopper limiting depth to 15 mm (Fig. 1).

2. Patients with closed physes

"Mosaic" osteochondral autotransplantation

If the patient's physes are closed and the osteochondral defect measures less then 10 cm2, we recommend "mosaic" bone and cartilage autotransplantation.

Planning the operation, it is important to determine if the full-scale osteochondral autotransplantation can be done arthroscopically, since it is not always possible practice this approach to collect donor transplant columns, do "mosaic" osteoplasty and articular surface congruence restoration [13, 14]. As a rule, the arthroscopic access itself imposes such limitations through restricting the use of instruments. Such cases call for "mosaic" chondroplasty (open or minimally invasive variations) [15].

There is an important aspect of surgery to consider, namely location of the transplants. Full-scale chondrogenesis and affected cartilage regeneration require transplants placed as close to each other as possible, almost sticking together or even slightly overlapping.

CT scans made 12 months after surgery prove that osteochondral regeneration in the "mosaic" zone went well (Fig. 2).

Up to early 2017, we resorted to "mosaic" osteochondral allotransplantation when the defect's area was greater than 10 cm2. We used lyophilized canned femoral condyles as donor allomaterial, which was sterilized with gamma rays. The surgery's technique and the arrangement of transplants were same to osteochondral autotransplantation (Fig. 3).

We believe that this method offers a number of advantages. First off, there is no need to collect autologous donor transplant posts from the sides of the knee joint, which makes the surgery shorter and less traumatic. Secondly, if the defect's area is small, the operation can be done arthroscopically. Thirdly, there is always a good supply of grafting materials, which allows using allotransplants of different diameters for full-scale osteochondral osteoplasty. Fourthly, there is no need to use biomaterials, which makes the surgery considerably less costly. Fifthly, localization of the osteochondral defect does not matter, the method is a viable solution for knee and other joints.

Today, we often resort to the combined (auto- and allo-) "mosaic" osteochondral transplantation (Fig. 4). Typically,

it ensures better regeneration of the subchondral bone and cartilaginous surface of the femoral condyle.

Here is the list of our recommendations pertaining to the osteochondral transplantation technique:

- full-scale osteoplasty of a osteochondral defect requires transplants with the diameter of 5-6 mm or greater;

- complete regeneration requires transplants placed as close to each other as possible, sticking together or even slightly overlapping;

- if the defect's area exceeds 10 cm2, adequate (pre-surgery) assessment of very possibility of complete elimination of that defect is crucial for success; combined auto- and

alloplastic approach is a viable solution when there is a risk of shortage of autoplastic material.

Subchondral bone microfracturing (Steadman technique)

From 2002 to 2005, when faced with a 3rd stage local femoral condyles cartilage defect (contacts, 5 cm2 maximum), we often resorted to subchondral bone microfracturing, or the Steadman technique [2, 4, 5]. This method implies stimulation of chondrogenesis by stem cells obtained through the openings formed. Analysis of the outcomes of such operations showed that they are prospectless: the Steadman's technique does not

deliver the results expected, i.e. cartilage does not regenerate in the affected area. These outcomes are a yet another prove of this fact: normal chondrogenesis requires anchoring stem cells in the cartilage defect area as a super-clot.

Autologous matrix-induced chondrogenesis (AMIC)

Lately, practitioners have been choosing the autologous matrix-induced chondrogenesis technique (AMIC) more often when faced with full-thickness cartilage defects (Fig. 5).

AMIC makes use of the above-described reparative ability of mesenchymal stem cells that enter the joint cavity through holes drilled in the subchondral bone [17-22].

Tunneling allows formation of a super-clot of cytokines and red bone marrow stem cells, which stabilizes through implantation onto the matrix defect and stimulates bone and cartilage-like tissue repairs [23, 24].

AMIC offers a number of distinct advantages: it is minimally invasive; it can remedy larger cartilage defects; it is a simple surgery; its effectiveness has been proved — patients suffer

lesser pain, in some cases the pain was gone completely and knee functions returned in full, which had positive effect on patient satisfaction.

Today, collagen matrix is the most advanced widely available biological material used to repair cartilage tissue, a material that positively affects stem cell differentiation and chondrogenesis.

We believe this operation is the proper choice for patients with 3rd stage of Koenig's disease (full-thickness defects of hyaline cartilage, no damage to subchondral bone). Prerequisites: healthy hyaline cartilage surrounding the defect, viable subchondral bone and unchanged mechanical axis of the lower limb.

Contraindications: multiple cartilage defects, including "kissing lesions"; widespread knee osteoarthritis; systemic autoimmune diseases; knee joint instability caused by ligament and meniscus injury; valgus or varus leg deformations that call for corrective surgery; allergic reactions to collagen.

Special attention should be paid to the state of the subchondral bone: expressed sclerosis there indicates its non-viability. We believe the non-viable part of the bone should be sanitated up to the healthy, bleeding layers, and the defect remedied through osteoplasty. Lack of pinpoint bleeding after subchondral bone tunneling signals of its non-viability, which should alert the surgeon. In such cases, implantation of a collagen matrix without osteoplasty is fruitless.

The list below presents our recommendations based on the analysis of long-term outcomes of AMIC technique application to our patients.

- A mandatory prerequisite for collagen matrix implantation is healthy and stable subchondral bone.

- Deep (over 5 mm) local damage to subchondral bone calls for osteoplasty on the osteochondral defect.

- Simultaneous osteoplasty (on the osteochondral defect, using a biocomposite bone) and matrix implantation is unpromising.

- Physical activity level of the patient should be factored in when planning the surgery. Unfortunately, AMIC and sport of records are incompatible.

CONCLUSION

Having analyzed the outcomes of treatment done in our hospital, as well as available literature and technical capabilities, we optimized the algorithm for surgical treatment of patients suffering from knee osteochondritis desiccans and arrived at a number of conclusions: 1) patients with open physes should undergo removal of the non-viable cartilaginous plate, sanation of the osteochondral defect and subchondral bone tunneling; 2) AMIC technique is the optimal choice for cases where there is a full-thickness local cartilage damage and undamaged subchondral bone; 3) local osteochondral defects measuring less than 10 cm2 may best be treated with "mosaic" osteochondral autotransplantation; 4) local osteochondral defects measuring 10-15 cm2 call for combined "mosaic" osteochondral transplantation.

In conclusion, we would like to note that through the objective analysis of errors and complications we have managed to change the stereotypes around local cartilage and osteochondral femoral condyle defects treatment tactics, sort out a number of unpromising technologies and improve the surgery procedures. Nevertheless, surgery on knee osteochondritis desiccans is still is subject containing many controversial issues.
