When knee arthritis affects only one part of the knee joint — such as the inner (medial), outer (lateral), or kneecap (patellofemoral) region — instead of damaging the entire joint, a partial knee replacement offers a more targeted, conservative, and effective surgical solution. Unlike a total knee replacement, where the entire knee joint is resurfaced, partial knee replacement surgery focuses only on the diseased compartment, preserving the healthy bone, ligaments, and cartilage. This allows patients to retain more of their natural joint movement, enjoy a faster recovery, and experience a knee that feels more natural post-surgery.
In Thrissur, a growing number of patients are choosing partial knee replacement surgery because it combines modern surgical innovation with improved outcomes and minimal downtime. One of the leading experts performing this advanced procedure in Thrissur is Dr Dinesh Sunny, a highly skilled and trusted orthopaedic surgeon. Known for his precision, compassionate care, and commitment to personalized treatment, Dr Dinesh Sunny has become a go-to specialist for patients suffering from chronic knee pain, early-stage arthritis, or joint damage confined to one compartment.
What Is Partial Knee Replacement?
Partial knee replacement, also known as unicompartmental knee arthroplasty (UKA), is an advanced surgical procedure designed to replace only the damaged part of the knee joint while preserving the healthy bone, cartilage, and ligaments. This means that instead of replacing the entire joint—as in a total knee replacement—partial knee replacement surgery targets only the affected compartment, whether it is the medial (inner), lateral (outer), or patellofemoral (front) part of the knee.
The primary goal of partial knee replacement surgery Thrissur is to relieve pain, restore smooth knee movement, and allow patients to return to an active lifestyle—without the need for a more extensive surgery. By preserving the natural structure of the knee, this technique helps maintain better joint stability, more natural movement, and faster rehabilitation.
This approach is particularly suitable for patients with osteoarthritis that is limited to a single compartment of the knee. Instead of undergoing a total knee replacement, these patients can benefit from a smaller surgery that retains most of their original joint and muscles.
Key Advantages of Partial Knee Replacement Surgery Thrissur:
Quicker recovery and significantly less postoperative pain
Smaller incision leading to minimal scarring and blood loss
Natural knee feel and stability, preserving ligaments and alignment
Shorter hospital stay and faster return to normal activities
Long-term comfort with durable implant technology
For individuals in and around Thrissur seeking lasting relief from localized arthritis pain, partial knee replacement surgery Thrissur performed by Dr Dinesh Sunny offers a modern, minimally invasive, and highly effective solution.
Who Is a Suitable Candidate?
Not everyone with knee pain or arthritis qualifies for partial knee replacement. Dr Dinesh Sunny carefully evaluates each patient’s condition using detailed clinical examinations, imaging studies such as X-rays and MRIs, and functional assessments before recommending partial knee replacement surgery Thrissur.
Ideal candidates include:
Patients with arthritis limited to one compartment of the knee
Individuals with intact ligaments, especially a healthy anterior cruciate ligament (ACL)
People with good bone quality and no severe deformity or stiffness
Those with stable knee alignment and moderate activity levels
Patients who maintain realistic expectations about recovery and outcomes
For patients with arthritis spread across multiple compartments or severe deformities, total knee replacement may be the more effective solution. Dr Dinesh Sunny ensures that each surgical recommendation is based on a thorough and accurate assessment of the knee’s structure and function.
Benefits of Partial Knee Replacement
Choosing partial knee replacement surgery Thrissur with Dr Dinesh Sunny provides a wide range of advantages over traditional total knee replacement, especially when performed on carefully selected patients.
The key benefits include:
Less bone removal: Only the affected area is resurfaced, preserving healthy tissue.
Faster recovery: Patients can often walk within a day or two after surgery.
Minimal pain and swelling: Smaller incisions lead to reduced tissue trauma.
Natural knee movement: By preserving ligaments, the knee feels and functions more naturally.
Simpler revision in the future: If arthritis progresses, converting to total knee replacement is easier.
High patient satisfaction: Most patients experience improved mobility, stability, and long-term comfort.
Patients who undergo partial knee replacement surgery Thrissur often report faster functional recovery and greater satisfaction compared to those who undergo total knee replacement—when the indication is appropriate.
Risks and Limitations
While partial knee replacement is a safe and reliable procedure, it carries some potential risks, as with any surgical operation.
Possible risks include:
Infection, bleeding, or wound complications
Blood clots in the leg (deep vein thrombosis)
Implant loosening or wear over time
Continued or new pain due to disease progression in other knee compartments
Rare cases where revision or total knee replacement becomes necessary
Dr Dinesh Sunny uses meticulous surgical techniques, modern implant designs, and evidence-based infection control protocols to minimize these risks and ensure long-term success for every patient undergoing partial knee replacement surgery Thrissur.
The Surgical Procedure Explained
The partial knee replacement surgery Thrissur process involves several precise steps, each designed to maximize safety, accuracy, and outcome quality.
Step 1: Preoperative Assessment
Before surgery, Dr Dinesh Sunny performs a thorough evaluation of the patient’s knee through clinical tests, imaging, and preoperative medical assessments. Planning involves selecting the correct implant size and mapping the exact angles for bone cuts.
Step 2: Anaesthesia and Positioning
The procedure is performed under spinal or general anaesthesia. The patient is positioned comfortably to allow the surgeon complete access to the affected knee compartment.
Step 3: Incision and Joint Exposure
A small incision is made over the affected compartment of the knee. Using minimally invasive techniques, the damaged cartilage and bone are carefully removed while preserving healthy structures and ligaments.
Step 4: Implant Placement
Precision instruments are used to shape the bone for the implant. Trial components are placed to check alignment, motion, and stability. Once confirmed, the final prosthesis is implanted and securely fixed.
Step 5: Closure and Recovery
The incision is closed neatly, and sterile dressings are applied. Patients are encouraged to begin gentle movement and walking within 24 hours under supervision.
Dr Dinesh Sunny’s surgical expertise, combined with advanced implant systems, ensures high accuracy, excellent alignment, and superior long-term results for patients choosing partial knee replacement surgery Thrissur.
Recovery and Rehabilitation
Recovery is a vital part of the journey. Under the guidance of Dr Dinesh Sunny and his physiotherapy team, patients are supported with a structured, individualized rehabilitation plan after partial knee replacement surgery Thrissur.
Typical recovery timeline:
Day 1: Begin walking with support and light exercises.
Weeks 1–2: Increase mobility with guided physiotherapy and pain management.
Weeks 3–6: Focus on strengthening quadriceps and improving flexibility.
Months 3–6: Resume normal daily activities and low-impact exercises like walking or swimming.
Consistent physiotherapy, proper nutrition, and follow-up visits help patients achieve long-term success and joint stability.
Other Treatment Options
Before recommending surgery, Dr Dinesh Sunny explores all possible non-surgical options, especially for patients with mild to moderate arthritis.
These may include:
Medications to control pain and inflammation
Physiotherapy and strengthening exercises
Weight management to reduce pressure on the knee
Braces or orthotic supports
Injections like corticosteroids, hyaluronic acid, or PRP
If these conservative treatments fail to relieve symptoms, surgical options such as partial knee replacement or total knee replacement are considered based on the extent of joint damage.
