Arthroscopy

Arthroscopy is a minimally invasive surgical procedure in which a tiny camera – the so-called arthroscope – is inserted directly into the joint through a small skin incision. What the surgeon sees there appears in real time on a screen: cartilage, ligaments, mucous membrane – all at a glance, without having to open the joint extensively. The procedure is suitable for both diagnosis and direct treatment of joint diseases.

Compared to classic open surgeries, the difference is noticeable: less tissue damage, significantly less pain afterwards, and dogs are often back on their feet surprisingly quickly.

When Is Arthroscopy Performed in Dogs?

The scope of application is broader than many dog owners expect. An overview of the most common indications:

1. Joint Inflammation and Arthritis: In cases of chronic inflammation or arthritis, arthroscopy allows direct assessment of how severely the cartilage is already affected – more precisely than any X-ray image.
2. Cruciate Ligament Tears: Especially in the knee joint, arthroscopy allows for an accurate diagnosis of cruciate ligament injury and, in certain cases, even immediate repair of the damage.
3. Osteochondrosis Dissecans (OCD): This developmental disorder of the cartilage leads to loose cartilage fragments in the joint. These can be removed and the joint thoroughly cleaned arthroscopically.
4. Elbow Dysplasia: A common problem, especially in large breeds – arthroscopy is considered a valuable tool here to find the cause of lameness and treat it specifically.
5. Mensiscus Injuries: Damage to the shock-absorbing meniscus in the knee can be both diagnosed and treated arthroscopically.
6. Unclear Joint Pain: Sometimes neither X-rays nor MRI show a clear finding. Arthroscopy then provides a direct view into the joint – and thus often the decisive answer.

Procedure of Arthroscopy in Dogs

The procedure is fundamentally performed under general anaesthesia. No dog should suffer or move during the examination. The typical course of events is as follows:

1. Preparation: First, the dog is thoroughly examined. Blood tests and imaging techniques – usually X-rays – help to assess the affected joint in advance and plan the procedure carefully.
2. Induction of Anaesthesia: The dog is put under general anaesthesia before the vet makes even a single incision.
3. Sterile preparation: The joint is shaved and disinfected – hygiene takes top priority here.
4. Insertion of the arthroscope: Through a tiny skin incision, the vet inserts the arthroscope into the joint. If therapeutic measures are required simultaneously, a second small opening is made for the surgical instruments.
5. Examination: The arthroscope transmits sharp images of the interior of the joint to the screen. Cartilage, ligaments, meniscus and other structures are assessed systematically.
6. Treatment: If necessary, therapeutic steps follow directly: removing cartilage fragments, flushing the joint or repairing damaged structures – all through the same small access points.
7. Conclusion: The instruments are withdrawn, and the incisions are sutured or clipped. Afterwards, the dog slowly wakes up from anaesthesia in the recovery area.

Advantages of arthroscopy in dogs

Why are veterinary surgeons increasingly turning to this method? Four points that make the difference:

1. Minimally invasive: Small incisions mean less tissue damage, less pain and a shorter recovery phase – both dog and owner feel this equally.
2. More precise diagnostics: Direct visualisation of the joint surpasses any indirect imaging technique, particularly for complex or hard-to-pinpoint problems.
3. Faster return to everyday life: Many dogs recover significantly faster after arthroscopy than after open surgery and resume normal activities sooner.
4. Less need for painkillers: Because the tissue is less traumatised, postoperative pain is often lower – which also reduces the need for pain medication.

Aftercare following arthroscopy

Faster recovery does not mean you can simply let the dog run around. Proper aftercare helps determine the outcome:

1. Rest in the first few days: The operated joint needs time. Running, jumping and exuberant play – all of this should be off-limits for several days.
2. Medication: The vet often prescribes painkillers and/or anti-inflammatory preparations to support healing and keep the animal comfortable.
3. Wound care: Keep the puncture sites clean and dry – this sounds simple, but it is crucial. A protective collar prevents the dog from licking the wounds.
4. Physiotherapy: In some cases, targeted physiotherapy is recommended to restore joint mobility and strengthen the surrounding muscles.
5. Follow-up checks: Regular check-up appointments with the vet are not a luxury, but standard practice – only in this way can it be reliably determined whether the joint is healing as expected.

Risks and complications of arthroscopy

Arthroscopy is considered a safe procedure – but no surgical intervention is completely risk-free. The following complications can, albeit rarely, occur:

1. Infections: The risk is low, but present. Infection can occur both at the puncture site and deeper within the joint.
2. Bleeding: In rare cases, slight bleeding occurs in the joint.
3. Pain and swelling: Some dogs show temporary swelling after the procedure or react with more pain than expected – this usually resolves on its own.
4. Temporary stiffness: The joint may feel somewhat stiff in the first few days after the procedure. This joint stiffness normally improves as healing progresses.
5. Anaesthesia risks: Every general anaesthetic carries a certain residual risk, particularly in dogs with pre-existing conditions. The vet will advise on this beforehand.

Conclusion

Arthroscopy has fundamentally changed joint surgery in dogs – for the better. Small incisions, clear images, targeted interventions: the procedure combines diagnostic precision with genuine patient comfort. Naturally, it does not replace careful aftercare, and as with any intervention, one should be aware of the risks. However, anyone who wants to offer their dog a gentler alternative to open surgery will often find arthroscopy to be the best solution.
