When it may be considered
Disabling pain, reduced walking or deformity after well-conducted non-surgical treatment has failed. An X-ray alone is never a reason to operate.

Orthopedic surgery
Four procedures on one page, explaining what surgery may relieve, the recovery it requires and the limits patients should understand before deciding.
General information only. A decision requires a clinical examination, appropriate imaging and assessment by a qualified surgeon.
01 · Knee replacement
Replace worn surfaces, then rebuild movement.
A total or partial knee replacement covers joint surfaces damaged by arthritis. Its main aims are pain relief and better walking, without promising that the knee will feel completely normal.
Rehabilitation shapes the outcomeRegaining extension and flexion starts in the first weeks. Physiotherapy should be arranged before travel and begin immediately after the patient returns home.
Preparation and aftercare
Clinical assessment, standing X-rays, infection screening, muscle preparation, clot prevention and early mobilisation.
Outcome and recovery
Relief of arthritic pain is usually the main benefit. Walking and independence improve over several months; flexion depends on preoperative mobility and rehabilitation. Lifelong radiographic follow-up remains necessary.
Risks and limitations
Implant infection, deep-vein thrombosis or pulmonary embolism, stiffness, wound problems, instability, residual pain, wear or loosening, fracture around the implant and possible revision surgery.
Frequently asked questions
The questions patients most often ask.
Often only with difficulty, and sometimes not at all. This is a common limitation even when pain and walking improve.
Yes. It should start promptly because stiffness established during the first weeks can be difficult to reverse.
Usually yes, with a longer recovery and more demanding work to regain flexion.
Often many years, but not indefinitely. Wear or loosening may eventually require revision.
The choice depends on how much of the knee is worn and on ligament condition. A partial implant is suitable only for limited disease.
Clot risk means the surgeon must set an individual waiting period and flight precautions before travel.
02 · Hallux valgus
Correct a painful deformity, not appearance alone.
Hallux valgus progressively shifts the big toe and changes forefoot loading. Surgery realigns the bones when pain and functional problems persist despite appropriate footwear and non-surgical care.
Pain—not appearance—guides the decisionSurgery is not recommended for a painless foot for cosmetic reasons. Recovery is long, swelling can last for months and no procedure guarantees future use of narrow shoes or high heels.
Technique
One or more controlled bone cuts realign the foot and are fixed with screws or wires. Surgery may be open, percutaneous or minimally invasive depending on the deformity.
Recovery
Limited walking in a postoperative shoe, elevation, carefully managed dressings and gradual return to normal footwear, driving, work and sport.
Outcome and recovery
Alignment changes immediately, but comfort should only be judged after several months as swelling settles and bone heals. Some stiffness or partial recurrence remains possible.
Risks and limitations
Prolonged swelling, stiffness, recurrence or overcorrection, transfer pain, delayed bone healing, irritating hardware, infection, sensory symptoms, thrombosis and complex regional pain syndrome.
Frequently asked questions
The questions patients most often ask.
Usually from the first days, but only in a special shoe and within the limits set by the surgeon.
Often only after several months because foot swelling lasts a long time.
This is not guaranteed. The medical goal is a less painful, functional foot—not access to every shoe style.
Yes. Partial recurrence can occur over the years because the underlying predisposition remains.
Sometimes, but it greatly reduces independence during the first weeks. The decision depends on the patient's circumstances and the surgeon.
The surgeon must approve the timing because swelling and venous clot risk may be increased during a flight.
03 · Herniated disc
Release the nerve when the clinical indication is clear.
A discectomy removes the disc fragment compressing a nerve root. It mainly relieves pain radiating into the leg or arm; it does not necessarily cure chronic back pain.
Imaging alone is never enoughMost disc herniations improve without surgery. An operation is justified only when symptoms, neurological examination and imaging match, or when a neurological emergency is present.
When it may be urgent
Progressive weakness, bladder or bowel dysfunction, saddle numbness, uncontrolled pain, or persistent radicular pain despite adequate medical treatment.
Procedure and recovery
Under general anaesthesia, a small incision allows the nerve root to be released with a microscope or endoscope. Standing starts early and activity returns gradually.
Outcome and recovery
Radiating nerve pain often improves quickly. Sensation and strength recover more slowly and may remain incomplete after prolonged compression. Back pain may persist and the disc can herniate again.
Risks and limitations
Recurrence, incomplete pain relief, neurological deficit, cerebrospinal-fluid leak, infection, compressive haematoma, thrombosis, scar tissue around the nerve, instability and anaesthetic risks.
Frequently asked questions
The questions patients most often ask.
No. Most improve without an operation. Surgery is mainly reserved for emergencies or persistent symptoms despite suitable treatment.
Not necessarily. Discectomy primarily treats nerve pain travelling into the leg or arm.
They often improve, but slowly. Recovery may remain incomplete if compression was severe or long-standing.
Yes. Recurrence at the same level is possible because the operated disc remains vulnerable.
Timing depends on the job, physical demands and neurological recovery. The surgeon sets the appropriate date.
The surgeon must approve the timing and precautions because prolonged sitting and clot risk need to be considered.
04 · Carpal tunnel syndrome
Release the median nerve before severe damage becomes established.
Opening the ligament over the carpal tunnel reduces pressure on the median nerve. Night symptoms often improve quickly; sensation and strength recover more slowly.
Confirm the diagnosis firstHand tingling can arise from the neck, diabetes or another neuropathy. Clinical examination and a recent nerve-conduction study should confirm the diagnosis before surgery.
Technique
Release may be performed through a short open incision or endoscopically, usually under local or regional anaesthesia.
Recovery
Finger movement starts immediately. Light tasks return early, but palm pressure, grip strength, driving and manual work require more time.
Outcome and recovery
Night waking often resolves rapidly. Sensation improves over several months and strength even more slowly; long-standing nerve compression may leave lasting symptoms.
Risks and limitations
Persistent symptoms, palm pain, sensitive scar, temporary weakness, rare nerve injury, infection, haematoma, stiffness, complex regional pain syndrome and recurrence.
Frequently asked questions
The questions patients most often ask.
Night symptoms often improve very quickly. Fine sensation can take several months to recover.
Often largely, but slowly. Recovery may remain incomplete when compression was old or thumb-muscle wasting was already present.
Tenderness on either side of the scar is common and usually settles over several weeks to months.
This is usually avoided because independence would be too limited during recovery.
Yes. It confirms the diagnosis, grades severity and helps rule out a neck problem or general neuropathy.
Soon for light work without manual strain; later for heavy work. The surgeon gives an individual timeframe.
